PATIENT REVIEWS

I do apologize for this WAY overdue review for Apex. I’m not even sure where to begin. From the moment I walked in I already felt so comfortable. I was greeted immediately and was told I would be having my free consultation in a couple minutes. The doctors came to meet me and I also spoke with them in regards to pricing because that was honestly a very big concern of mine. They gave me a very reasonable price! The office was extremely clean and they always had great music playing. I think what I enjoyed most were the people there. They really make sure you feel comfortable and you basically become a family! Dr. Kim and Dr. Lee are the most down to earth orthodontists, if not people, I have ever met. Don’t let that discourage you and think that they are young doctors that have no idea what they’re doing. They definitely are young but they know what they’re doing! I like that they treat you like family and not just a patient. Jennifer worked on my teeth for the most part, she is gentle and hilarious! I’m sure they know how uncomfortable it is to have something forcibly make your teeth straight and they understand. I have never had a bad experience with Apex. I was told from other orthodontists that my teeth would take about two to three years to fix.. Apex got it done in one and a half years and it looks amazing! The timing was also very important to me because I was not down to get married with metal across my teeth. I am so glad they made it happen! I obviously gave them a shout out at my wedding :] They are also very flexible with appointments and will work around your schedule. I definitely recommend them and have been recommending them to my friends and family. While I was there I would always have children on the chairs next to mine and I can always hear Dr. Lee and Dr. Kim be very patient with them. Overall, I’m very happy with how my teeth turned out and my experience there. I hope everybody’s experience at an orthodontist was as great as mine.

I chose Apex Orthodontics based on all the positive reviews on Google and on Yelp. I was also glad that they had opened up a second location in Whittier, which made it all the convenient as I live in the neighboring city. So far, my son has received nothing but pleasant experience from Dr. Kim. She is friendly, knowledgeable, professional and patient. You feel at ease with her. The staff is nice and friendly as well. The office setting is clean and comfortable and parking spaces are plentiful. I highly recommend Apex Orthodontics!

I noticed that my retainer was broken and decided to go to Apex Orthodontics to get it checked out. I’m so glad I did because Dr. Kim is so knowledgeable and actually takes the time to explain your options. My previous orthodontist rarely took the time to even say hello and I always felt like I was in a factory; at Apex, the entire staff makes you feel welcome and warm. Dr. Kim explained why my retainer wasn’t fitting correctly and how that affected my teeth. Then she broke down the pros/cons of the different types of replacement retainers I could get without making me feel pressured to make a decision right then. I highly recommend Apex to anyone looking for orthodontists who are professional, friendly, and trustworthy. Now, months after getting my new retainers, I’m very glad I made the decision I did!

Beautiful office, attentive and friendly staff, and Dr. Kim was so sweet! I am very happy that my dentist referred me to Apex! I love the fact that they give you a tour of the office before hand (knowing that the parents have to stay outside due to COVID), that was very thoughtful knowing exactly where your child will be and that their experience will be pleasant and not frightening. My son had a blast and I was very impressed at the time the dental assistant showed my son and I at the end for instructions on caring for his new braces. The account manager (I forget her name) was also very informative and didn’t rush through the process at all. I also felt that the cost was a great investment for 2 years worth of treatment and they were very flexible with setting up an affordable plan. Thanks Apex!

This dental office is without a doubt the best one i’ve had the pleasure to be apart of.  They treat every patient with care from old to young.  The office accommodates awaiting patients with fresh cookies,coffee /tea and movies. The dentist Dr. Kim & Lee are extremely knowledgeable and always have the patient’s best interest at heart. The staff is equally amazing, Sandy and Vanessa will make you feel at home with their pretty smiles and kind hearts and  you’ll love walking in and seeing Claudia greet you. I highly recommend this office to anyone in need of orthodontic work you won’t regret it.

From the front desk, Vanessa and Claudia to Dr. Lee and Dr. Kim everyone is great! They treat me like I’m part of the Apex family and that’s what sets this place apart from any other orthodontist. Yes, the end goal is achieving the perfect smile by using modern technology but it’s also about the journey you experience; the laughs, hospitality and detailed explanations for any concerns. It really is a great establishment and I highly recommend this place to anyone looking for that perfect smile! When my daughter gets older and if she needs braces, I will definitely be bringing her here.

I recently started treatment at Apex Orthodontics after getting a referral from my regular dentist.  I visited the West Covina office to inquire about the process and to evaluate the facility.  I immediately noticed how clean and cheerful the office appeared, but more importantly I noticed how friendly and attentive the entire staff was, from the receptionists to the dental assistants, and the Doctors themselves.  I received an examination from Dr. Kim, who clearly explained the various types of orthodontic treatment, and how each type would apply to my case.  Based on what I saw and experienced, my husband and I decided to begin treatment.  Sandy, the practice coordinator, welcomed us and  explained our insurance coverage, and helped us set up a payment plan that worked on our schedule.  She answered all of our questions, and didn’t make us feel rushed in making decisions.  At my appointment yesterday I was seen by Dr. Lee.  I found him to be just as welcoming and friendly as Dr. Kim.  He explained what to expect in the future on my treatment, and gave me advice on using my Invisalign appliances.  I’m glad I chose Apex Orthodontics!

My dentist referred their office to me and I have been nothing but pleased with my decision. It’s only been seven months but everything has been super so far. The friendly staff greets you by name the minute you walk in which is impressive since they see all kinda of people every day. It makes me feel very special that they know their patients. I decided I wanted to try the Invisalign’s on my teeth. I did not have braces on when I was younger so I wasn’t really sure what to expect. Dr. Kim told me I was a good candidate. They set me up with a monthly payment plan for the difference after insurance.  You do have to be disciplined enough to wear them all the time except when you’re eating. No one can tell I have them on when talking to me which is really nice. I hear a little lisp but that’s it. Each week the trays move your teeth. At first it feels a little tight on your teeth but then you adjust to it. I really like the fact that I take them out to eat . Yipee! If you have traditional braces there are certain restrictions,what you can or cannot eat. Once I am done eating, I just brush my teeth and I am good to go.  I am now at the phase that my bite is changing because when I am eating I sometimes bite down too hard. Yikes! My fault. The office gives you about six weeks of trays at a time and then you go in for a check up. They are very interested in your progress and answer any questions you might have. They are very patient with me. Daisy has been very helpful to me. Even though Dr, Kim is my doctor, Dr. Lee greets me kindly as if I were his patient too. They value customer service and it shows. All of the girls appear to love their jobs because they are smiling and laughing with their patients. The Disney music playing just puts you in a great mood. I have to give a special shout out to Sandy for going above and beyond in caring for my needs. She really cares about us and I am truly grateful. Oh, I don’t want to forget the office is very clean. They decorate for the Holidays. They have these toothbrushes that have toothpaste already in them which is so cool. I would highly recommend this office.

My daughter started getting treatment in Jan/2018 and it has been the best decision and investment we’ve made! Dr. Kim and Dr. Lee have been so amazing and the whole staff is very friendly and professional! The whole ambiance of the dental office is very welcoming and we love the modern design. Their dental equipments are of high quality. They walk you through the whole process and explain everything in detail. My daughter has a severe underbite and in 6 months, we’ve seen a huge improvement! We found out about Apex through our dentist and I don’t doubt why they get a lot of referrals. We highly recommend this place!

Great practice! Really welcoming environment 🙂 When my fixed retainer broke Dr. Kim was able to see me so quickly it was a lifesaver.  I was so happy to get a different option after 15 years of dealing with a fixed retainer.  The doctors give really great advice depending on your wants and needs.  I love that their waiting area is great for family and the office is really warm and inviting.  Their staff also is great with reminders and accommodating for schedules and appointment times.  If you want orthodontists that have a lot of knowledge, are easy to be around and give really practical advice and recommendations I definitely recommend Apex!

Had my braces removed today & so happy with the results!!  My teeth were all crunching together & moving forward.  The Dr’s  Dr Kim & Dr Lee( husband & wife team) & Staff were so amazing & friendly & very professional.  Nice clean environment! They are all so kind & warm , they  make you feel like you are visiting family & friends.   I highly recommend Apex for your Orthodontic needs.  They just opened a new location in Whittier if closer than West Covina. Thank you for such a great experience & getting it all done before my sons wedding as promised!

I love this place! Our dentist referred us over for our daughters severe overbite and I am very impressed by the staff and the doctors. We had our consultation a few weeks ago and at first it seemed overwhelming when you walk into their full lobby but they are such a well oiled team everything flows perfectly. They were kind enough to work with us and had very reasonable finance options. Today our daughter had her top set go in and I was a nervous reck. They were kind enough to let us sit right next to her and everything went perfectly! very informative and efficient. No need to shop around or look anywhere else. Go here they will take care of you! Very pleased I was able to help my daughter work on her beautiful smile.

I don’t know why I decided to get Invisalign around the same time I was planning to get married but Dr. Kim has been so accommodating to all my Bridezilla demands! I was referred to her by a friend who got amazing results with Invisalign. I went to a free consultation and decided that I would be better off getting started even though I wouldn’t finish until after my wedding. Dr. Kim assured me that my teeth would start to show results and be straighter in the 5 months before the wedding and I have already started to see results. She has been so nice to accomodate the fact that I need to be smile ready for my big day and allowed me to make appointments immediately before and after the wedding so that I can remove a few attachments that come with wearing the braces and then quickly re-attach them so I wouldn’t lose any progress I’ve made. Both Dr. Kim and Dr. Lee have been so accomodating even when I have to ask emergency questions about my braces. They are easy to reach and answer all my questions thoroughly and professionally. Their office is a BIG change from the orthodontist I went to as a child (lesson to all the kids out there: WEAR YOUR RETAINER OR YOU WILL NEED INVISALIGN LATER). Everything was clean and beautifully designed. I feel calm and at ease in their lovely office. I don’t write many reviews unless service is amazing and I highly recommend this office.

I am halfway through my Invisalign treatment, and I couldn’t be more pleased with the results so far (update to come post-completion). Dr. Kim thoroughly explained to me that results would vary based on the level of commitment from the patient–I really appreciated the fact that expectations were accurately set beforehand, as it encouraged me to be a more dedicated patient. As a formerly traumatized dental patient, I also found Dr. Kim’s gentle demeanor and patience explaining every step of the way to be extremely reassuring. She really knows what she’s doing, takes the time to listen, and is thoughtful in developing the best treatment path for what you’re trying to achieve.  I’ve already recommended Apex to a couple of my friends!  Also their office is SUPER clean and nice, which makes for all the better ortho visits!

My son whose 8 (almost 9) was referred here by his primary dentist from San Gabriel. When I first came I was impressed by the set up, modern office, kid friendly atmosphere, friendly customer service! I signed up for his braces during the consultation , payments helped with no interest. He has severe overbite (from sucking bottle in sleep, pacifiers, also I had one too) so he will need 2 phases! Phase one to help overbite and phase 2 when his adult teeth come in! Hope this review help give some parents ease! I’ve had a pleasant experience so far!

I always have great service at Apex. I’ve rescheduled my appointment for earlier times the same day as my appointment, and they always squeeze me in. I’ve also had a wire pop out, and the same day they were able to see me. I’m glad I found them, their staff is friendly and professional. I was seeing Western Dental, before Apex. Western Dental is the worst!! Thank you Apex for giving great customer service.

Wow what can I say about The Apex Team … well they are honest, make you feel amazing, very customer service oriented, they are caring, etc. I mean the list goes on for this team. Yes I am talking about a Orthodontic Office!! Dr. Lee & Dr. Kim are passionate about what they do and it shows every single visit. Hands down VIP service. Dr. Kim, Dr. Lee & the Team manage your treatments to the fullest. They are patient and really take the time to explain what is happening at every visit to make you feel comfortable. I recommend Apex to everyone! Make your appointment. Trust me when I say this is a life changing choice & why not take it with Apex Orthodontist. Ps . Did I mention they seriously have the coolest office ever!!! I wish I can start my mornings there everyday & then go to work.

I can’t stress enough how much I enjoy my appointments at Apex. There’s always so much love in here with the people that work here. Idk how they pick their employees but they do such a great job because I always feel the great energy of this place. It’s going to be a year next month that I’ve been coming monthly for my appointments, it’s flying by and my teeth are looking better and better. I really love how they walk me through every step they’re doing before they even do it and how they walk me through what I might feel, they also always give me wax or whatever I need for my braces without hesitation. It’s just one of those places that you know everyone loves their job& it’s a beautiful thing.

SO WHERE DO I START. I have been a member/patient of Apex Orthodontist since Dec of 2019. First things first, when I came to apex at the age of 28 & I never had braces. Growing up I was one of those people that got made fun of at times throughout my life because of my crowded teeth. As I grew older Ive learned to accept for what I have in life and accept that one day my teeth would be straight. That being said, since I have been here, I never, not once have had a awkward, horrible or uncomfortable experience. The staff here are very welcoming, they treat you like you are a family friend, and although they are wearing masks & you can’t see that they’re smiling, you can see the smile in their eyes. Every visit is something to look forward to, not just because you’re in the process of getting your teeth straight, but the experience Everytime you come here. I highly recommend anyone to come here cause you won’t find a more welcomin/ family vibe orthodontist around the area.

What to say about Apex that hasn’t already been said in a previous review… Drs. Lee and Kim are some of the best and most honest orthodontists I’ve come across. It amazes me how they are able to successfully blend a combination of professionalism and warmth in a single visit. They’re accomplished and knowledgeable about their trade and they always make sure that you’re making a decision based on what’s best for you (not exactly something you find in a lot of people these days.) I’ve since moved to Texas but Apex has set the bar for what I consider to be what other orthodontists should strive to emulate. Thank you! Did I mention, the Apex Orthodontics mobile is pretty bad ass.

When I first walked into Apex Orthodontics, I didn’t know what to expect. I was kind of nerves about getting braces and ever since I was little I hated going to the dentist. Going to the dentist was a place where they hurt your teeth, gave you lectures about brushing your teeth everyday, and made you wait a long time before they actually started working on you teeth. However Apex Orthodontics is different, they still lecture you about brushing your teeth and your teeth will definitely still hurt but they have a passion for their work and make the time fly by. Apex Orthodontics has done the impossible they made going to the dentist fun!!! Everyone there smiles and treats you as a dear friend (Like Suzyy who defiantly deserves a 10% raise 🙂 for being so cool). It is sad leaving knowing you won’t be back for a while, and you just can’t wait to go back.

So where new to the area and have been planning on getting our daughter braces for a while but have been putting it off. After making a decision to finally go through with it we came to Apex Orthodontics which turned out to be the best decision we’ve ever made. From the moment you walk in the girls in the front make you feel so welcomed. And sandy where do i start… she is so sweet makes you feel like you’ve known her all your life she’s very patient in explaining everything and makes sure you leave with all your questions answered. Dr. Kim and Dr. Lee are also amazing my daughter says there are super nice and make sure she’s comfortable the whole time. Thank you to the whole team at Apex Orthodontics.

After I had a car accident which left me with 15 fractures from the neck up and a lot of missing teeth I needed to find a orthodontist that had a lot of experience. I found that here at APEX. The staff here has a lot of experience and truly listens to their patients. When I voiced my concerns about not wanting to have further surgery to correct the slight tilt in my jaw Dr. Kim was honest and said that they can’t assure me that they could correct it but they can fix my bite and make things comfortable. This makes me feel comfortable and confident in my treatment. Sandy was incredible explaining the treatment cost and all of our options. She was so nice and patient explaining the different insurance plans and giving me information an how insurance works. She always answer my questions. I love it here.

Before I started treatment I had visited other orthodontists and they had told me I needed surgery so I could have the smile I wanted. When I got my consultation at Apex Orthodontics I was expecting them to tell me the same thing but I was wrong, they surprised me with the news that they were able to correct my bite without surgery. To my expectations everything is looking great. Not only the doctors are nice but they also pay attention to detail and the work so far has been amazing. Best office ever, don’t think twice this is the office to go.

Getting braces at any point in life can seem like an overall terrible experience, but the Apex team makes the experience as comfortable as possible. I started my journey with Dr. Kim and Dr. Lee almost 2 years ago, and though 2 years sounds like an eternity both Drs and their staff made the time fly by. The best part of it all MY TEETH LOOK AMAZING and I never dreaded coming to my appointments. If you are in need of braces or just playing with the idea, give the Apex team a call, you will not be disappointed.

I was referred to this office from my dentist and absolutely love it! I was a little nervous about getting braces and the amount of pain it would cause but everyone at APEX orthodontics has made the experience so wonderful! They really make you feel comfortable! I got my braces in February and I honestly look forward to going back every month because they have such a warm and friendly atmosphere; the entire staff is always so happy and excited to see you. They also have water, tea, coffee, and delicious chocolate chip cookies out for the patients to grab so that’s always nice!

My preteen son had his 1st appointment today with Apex Orthodontics for an initial braces consultation. He gives is a 5 out of 5 and so do I. The ladies in the front desk greeted us in a nice friendly manner. Since it was our 1st time there, we got a tour of the facility from one of the assistants. The facility is clean and spacious. Once finished they took digital radiographs. Dr. Aileen Kim met with us to go over the treatment that my son needs. She is pretty awesome! Friendly and knowledgeable. After this my son had to get impressions done. This is where it got a little tricky since my son has a strong involuntary gag reflex. My son said that when he was gagging they “had tricks up their sleeves to make the gagging stop”…. so they are good with kids and make them feel comfortable 🙂  He is also looking forward to have his picture taken once his treatment for braces gets started. You have an option to have your picture taken and it gets put on the wall for everyone to see. The experience was great. I will be booking an appointment for myself soon.

I recently became a patient at Apex Orthodontics and I am so relieved I found the right team. From the second I walked through the doors I felt like I was in competent and caring hands. I can not say that about many of the other offices I scouted out before selecting Dr. Kim’s office. The office is clean and spa like. The technology they used look top-of-the-line. My consultation was thorough, I was educated on my facial and bite symmetry! It was very interesting to me to learn all these things about myself that other offices failed to teach me. I’m so thankful I found a professional group with down to earth patient care!.

Everyone at Apex have been amazing and are so accommodating! We had a very welcoming consult with Sandy. The reception ladies, Vanessa and Claudia, have been amazing and put up with our crazy flex card company :-/ They have patience of angels. Dr. Kim and Dr. Lee are always wearing smiles. I love their modern technology. We love them all so much that we just started my youngest son with the process, while our eldest is midway. Thank you, Apex!!

The staff in Apex Ortho are awesome the services are good all.of them are friendly most Sandy she has a patience to us and she’s trying her best to explain everything in a way that we can understand easily and the doctors Dr. Kim and Lee they are very friendly to their patients and they are really taking care of you and no worries and my son never complain to his teeth the schedule is flexible easy to change as long as you call them in advance and in time.my son has a problem on his spacer we went there they fix it right away and most my experience there last mother’s day they gave my son rose to give it to me I won’t forget that. Thank you Apex for all your good services and thank you for all your smile.

My daughter started getting treatment in Jan/2018 and it has been the best decision and investment we’ve made! Dr. Kim and Dr. Lee have been so amazing and the whole staff is very friendly and professional! The whole ambiance of the dental office is very welcoming and we love the modern design. Their dental equipments are of high quality. They walk you through the whole process and explain everything in detail. My daughter has a severe underbite and in 6 months, we’ve seen a huge improvement! We found out about Apex through our dentist and I don’t doubt why they get a lot of referrals. We highly recommend this place!

This review is beyond long over due, first and foremost I’d like to say thank you to the amazing staff, we are proud to call our “Apex family” especially the awesome Claudia! Her perky self and smile along with the team you can tell off the bat they are the heart of the office. This office is so welcoming, and I must add CLEAN!!! That’s definitely number 1 in my book. Dr. Kim and Dr. Lee whom we owe my sons gorgeous smile to are absolutely the BEST in the business! The two are so sweet, caring and everything you would want and expect from your doctors caring for you/your child. We made the greatest choice of all for coming to Apex and we wouldn’t have it any other way. If your reading this make sure to come check them out! Ps they usually have fresh delicious cookies waiting for you  my favorite part while waiting for my son.

These are 2 of the best doctors I have ever encountered! It’s hard to find care that is completely professional but also friendly and personable. Dr.’s Kim & Lee made me feel at home and comfortable during every appointment. I can’t wait until my kids need braces!!!! I would recommend them to everyone in the area!

Apex was the best choice for us after reviewing and consulting with two other Orthodontists. The staff is well trained and customer centric, from the beginning they made us feel that they aim to provide an exceptional customer experience, and they did well with that. Our journey is just about over as we move into the retainer phase, time flew by and it was “painless for me the parent”, for my son, the results are a perfectly aligned set of teeth from a complex treatment start. Great job guys!!!’ Certainly the first place to go for orthodontic services!

I came for my and my 9yr old daughters braces consult. Natalie and Dr. Kim were so welcoming and made us both feel comfortable. They deacribed in detail the process and were patient with any questions we had. They didnt seem like they were in a rush to move on to the next patient as other offices may seem. I git my braces on next day, my daughter goes in a few months after some baby teeth fall out. Check them out they are clean, friendly, and overall amazing.

A WORD FROM YOUR DOCTOR
