Check out what some of our happy patients are saying about us:

Beth W. from Claremont, CA (Source: Yelp)


Every visit to Claremont Modern Dentistry is pleasant and effective. This past month I had the occasion to be in the office for three separate visits, one of which was a root canal. Each time the staff – including the team at the front desk and Klara and Cassandra in the treatment rooms –  has been welcoming and exceedingly professional. Dr. Lee is a remarkable dentist and her skill is surpassed only by her humanity and kindness. The endodontist they contract with is efficient and easy to work with. I don’t love going to the dentist, but I love how I’m treated once I’m there

Marsha J. from Rancho Cucamonga, CA (Source: Yelp)


My kids needed a lot of dental work done this past summer and I was really struggling where to go.  My daughter was in pain and I called their office and they got her in that day.  Dr. Lee is her fairy godmother now!  She is amazing.  She worked with me with the cost since my daughter had so much work to be done.  My daughter can’t keep from smiling now! The staff was wonderful and answered all my questions.  They helped making all of this a very positive and friendly experience.  It is also nice that they have specialists to meet all of your needs.  I highly recommend their office!

JR. E. from Mission Bay, San Diego, CA (Source: Yelp)


Going to the dentist was always something I put off. Since I started coming to Glendora Smiles… my kids and I haven’t missed a check up. I love Dr. Lee. She takes the time and explains everything in detail. She is also very good with my youngest child as well. No fear at all when they come in. It’s nice knowing she’s a mother as well and takes extra time to make sure the kids are comfortable. Leilani is amazing as well. She always finds a way to fit us in with our crazy schedules.

Bianca S. from Pomona, CA (Source: Yelp)


Going to the dentist has always been nerve wrecking but Dr. Lee and her staff made the visit pleasant. The front staff was kind and friendly and her staff in the back were just as courteous. Cassandra her assistant is so nice and friendly. Recommend this spot to anyone in need of a dentist!

Jessica V. from West Covina, CA (Source: Yelp)


This is the best dental office that I’ve been to in years. I was nervous about switching dentists, but the staff and dentist were great! When I first got there the office was super busy, but the girls at the front desk were so friendly and helpful. Loren took care of me when it came to filling out paperwork since I was a new patient. Even helped me with an insurance issue I had. The dental hygienist who did my cleaning was so good and patient. Overall just a great experience for it being a dentist visit! I definitely recommend this place!

I love this place, everyone here is wonderful! I get extremely nervous when going to the dentist but the staff here makes everything so much better! A great place to have the ol’ chompers worked on!

Phil T. from Ontario, CA (Source: Yelp)


I haven’t been to the dentist in about 15 years cause of fear.  Has no choice due to a bad toothache.  Everyone here was amazing. Dr Soojin Lee and Casandra finished installing my crown today. Piece of cake. No pain. Highly recommend this dentist office. Thank you to the entire staff for making this procedure very comfortable

Carlos B. from Fontana, CA (Source: Yelp)


I came in the office and the I was amazed on how clean the office is  and how up to date with technology they are. As a walk in I was helped very quickly and Mariela helped me with verifying my insurance. I received all my options for my treatment by Mariela and made my choice very affordable to my budget. I have finally found an office that sees me as a person and not a number. Thank you so much!

Liz C. from Fontana, CA (Source: Yelp)


Just went in for my routine check up & cleaning everyone is so welcoming. I always enjoy coming in & getting my cleaning done. Mariela helped me with my insurance copays she was very nice & answered all my questions. I cant wait for my next check up, will def. Tell my family & friends.

Lucio B. from San Bernardino, CA (Source: Yelp)


I came in last week for my first visit. My experience was great from the time I called to book my appointment. When I arrived for my appointment, I was seen quickly as I completed my paperwork online(amazing no paperwork at the office). Once I was ready to hear my cost I was helped by Mariela and she explained my benefits very well and she offered me payment options(OMG what dental office offers in office payments). I highly recommend this office and ask for Mariela she is very knowledgeable on working with your benefits and budget.

Ara M. from Los Angeles, CA (Source: Yelp)


I have been coming here for more than 2 years now and I always have pleasant and wonderful experience. Dr. Lee is so gentle and very kind. Karla is always very courteous and friendly. She makes me feel relaxed everytime I go there. They made my dental visits very easy and comfortable. I would recommend this office to anyone who’s looking for a new dentist. They really accommodate their patients.

Jorge R. from Fontana, CA (Source: Yelp)


I have been to three different offices and almost gave up because my mouth is so “complicated” I read all the reviews and decided to give this office a try as my last attempt! Loren answered the phone when I called and got me In the next day with Dr. John, he came to get me from the waiting room! The doctor! I thought it was weird but he just wanted to chat before we got into the X-rays that’s never happen before. Cassandra was so sweet with the X-rays I know Im not the easiest:) but we made it through without any missing fingers!! Long story short Dr. John gave me a realistic plan on how to get where I wanted to get. I needed 8 teeth extracted and deep cleaning with laser. Cost me a pretty penny but I don’t have to hide my smile behind my hand anymore and to me that’s priceless. Dr. Mashhadian is the most sarcastic funny man I’ve met but my recovery from the extraction was so minimal He said it didn’t even look like I had extra teeth! My gums don’t bleed when I brush or floss and my braces are on. I’m so happy I did this and I couldn’t of done it with out these guys thank you so much I can’t express how happy I am to just smile!! You gained a patient for life!

Leticia V. from Cypress, TX (Source: Yelp)


I wanted to take the time to give Claremont Modern Dental a review, it is the least I can do after an awesome experience I had with their staff.  I had neglected my teeth for years, since I had been blessed with straight beautiful teeth.  As I have aged and taken medicine that has destroyed my teeth, I had to have major dental work done, needless to say, I  was horrified.  The staff was amazing right from the reception area, friendly and helpful thru check in.  My first visit to them consisted on a deep cleaning, Nancy was amazing and the process was painless.   After a while I needed major dental work done, Bryant and Dr. Lee were so amazingly friendly and spoke to me in simple terms,  not in medical terms.  In my many visits with this office, I have nothing but gratitude to the entire Staff.  THANK YOU!!!!

Eder L. from Pomona, CA (Source: Yelp)


I use to dread going to the dentist… Since I’ve started coming here (2015) my view of going to the dentist has completely changed. The receptionists, RDA’s, hygienist, Doctors, the entire staff is outstanding. Everyone is very easy to talk to and they explain everything they do. They honestly try and make the visit as relaxing as they possibly can. I have the utmost confidence that I am in good hands every time I go in. I Highly recommend them to anyone out there.

Cheryl C. from Upland, CA (Source: Yelp)


Hands down Claremont Modern Dentistry is the best dental office that I have been to.  After spending the past 3 years in pain from two root canals and a crown that fell out twice and numerous trips to a different dentist, I pretty much had given up and was terrified of dentists.  I decided to check Yelp reviews for a dentist in the Claremont area, and read about Claremont Modern Dentistry and Dr. Lee.  Desperate to find a dentist to help me, I called the office to inquire about an appointment, and it was the best decision that I could have made regarding my dental issues. Dr. Lee has been so compassionate and determined to resolve my dental pain and problems.  She listened to my past medical and dental history and truly seem to care.  She has gone above and beyond to fix my teeth. She has been extremely gentle during the procedures and has always made sure that I was comfortable. Her staff is incredible and also extremely caring towards patients. From the minute that I called to make an appointment, to when I walked in the front door, the front office staff has always been kind and so helpful with my appointments, treatment plan and insurance coverage. The back office staff is amazing and go out of their way to make sure that patients are comfortable.  The entire office staff works as a team and all help each other.  I have had several appointments due to the complexity of my dental problems and the staff has always been consistently compassionate and caring. Nancy, Chris, Bryant and Amanda have been involved the most with my treatments. They are all highly trained and professional throughout procedures, X-rays, cleanings and treatments and always strive to make sure that I am satisfied with the outcome of the visit. I highly recommend Claremont Modern Dentistry. Dr. Lee and her staff have given me my mouth and smile back.

AJ. R. from San Francisco, CA (Source: Yelp)


I was a bit apprehensive about the visit and the procedure, but it went far, far better than I expected or anticipated. I am very satisfied and happy to have found Dr Lee and Kathleen Pangilinan and Glendora Smiles. The office and support staff were very kind and helpful as well. I’ve already recommended the team to a co-worker!

Jay H. from Chino Hills, CA (Source: Yelp)


Dr. Lee is the most thoughtful, caring, responsible, honest, and personable dentist I have ever had. She is SO good at what she does. I have followed her from her previous office because she takes care of me the way she would take care of her closest family member. Her staff reflects her wonderful leadership. They flexible payment options and her fees are very reasonable. If you are looking for a dentist, GO SEE HER!!!

Mary M. from Claremont, CA (Source: Yelp)


My recommendation for Claremont Modern Dentistry is a rousing 2 thumbs up! I’ve never been to a dental office that treated me so well before. I HIGHLY recommend them. Dr. Ravi and Chris made me extremely comfortable throughout my dental ordeal. I say ordeal because I was there literally all day. Not for fault of there’s but for what I needed done. The were patient, kind and thoughtful. PLEASE check them out. You won’t be disappointed.

Erin O. from Rancho Cucamonga, CA (Source: Yelp)


I just went in to Glendora Smiles because I broke my tooth.  They were able to get me in the same day!  The staff was really nice and professional.  I was really scared, because I hate getting any dental treatment done.  I have to say this was the best experience.  Dr. Lee was really gentle and it didn’t hurt at all.  Kiara and Theresa were awesome assistants.  They kept checking on me to make sure I was okay.  Plus, I got my crown the same day!  I don’t have to come back!  This was literally the easiest process.  I would definitely recommend coming to this office.

Chuchis Y. from South El Monte, CA (Source: Yelp)


I was looking for a dentist around my area and came up with this location which i absolutely love and will continue to go for my check ups. i felt welcomed by this place and there staff was very helpful. I would like to thank Mariela for all her hard work and helping as far as benefits and making the right choice. Next time anyone goes, mariela is the right candidate to speak to! Love this place for keeping my teeth in shape.

Ebony C. from Duarte, CA (Source: Yelp)


I began service with this location a little over 2 weeks ago. My first impression of the office was by a phone call with Leilani. She was very personable and willing to help with accommodating a visit last minute due to tooth pain caused by 2 of my wisdom teeth.  I explained that my current dental office was not getting back with me and trying to schedule me two weeks out due to not having an anesthesiologists on staff until then.  I was then connected with Georgina who was just as personable and professional. She made time for me to come in same day to get X-rays done and got them to the Dr. for approval. I was then scheduled for that Friday to have my tooth extracted. Problem solved! Recently went in for my follow up appointment to make sure I am healing well with Dr. Lee who is genuine and  professional. This office is thorough in explaining procedure and pricing. I am happy with the level of service provided thus far!

went in feeling nervous and anxious.. with five tooth extractions, the team at Claremont modern dentistry made sure to properly and efficiently describe my surgical procedure. with all the high tech gear that they have I felt totally confident and safe that they were going to take good care of me. I’d like to thank everyone for all the help and hard work they provide me with. I’ll totally recommend their service to anyone looking for top notch dentistry.

Everardo A. from Westmont, Pomona, CA (Source: Yelp)


Not having been to the dentist in quite some time, the staff at Claremont made it such a breeze! Im greeted by everyone from the time I walk in, reception to the staff in the back. Dr. Lee is the dentist who I seen and she is absolutly amazing, Cassandra the assistant who was with her is great! Happy with the work I had done, will be returning for my dental up keep! Recommend this place to everyone!

Brian M. from Montclair, CA (Source: Yelp)


When it comes to going to the dentist I dont like to go because I have had many bad experiences. But still we all most go sometime so when it came time for a dentist visit my sister referred me to this office.  She spoke very highly about the staff and since I trust my sister I figured I would give them a try.  Sure enough my sister was right. The office was clean and the staff very friendly.  Loren was my coordinator and she went over my treatment very thouroughly and was very nice.  She answered all my questions and made me feel comfortable in a place I am normally not.  I plan to use them for all my future dentist needs and I would highly recommend them

L. Manuel T. from Las Vegas, NV (Source: Yelp)


I came in as an emergency because my crown fell and being away from my town was difficult to locate an office to see me as an emergency. Well, searched on the web and located Claremont Modern Dentistry. I walked in and Mariela helped with adding me to the schedule and with my insurance. Although my insurance didn’t cover much I was offered payment options which was great because being so close to Christmas I didn’t want to add an additional expense. I had another crown made as my old crown actually broke off and they were able to make my crown there and on the same day!! I will definitely recommend them to my coworker in town and back home when they travel to CA. I was very impressed. Thank you

Constantine C. from Long Beach, CA (Source: Yelp)


Glendora Smiles, is a pleasurable experience. Also staff members are appreciable and worming especially Arantza. She is patient and understanding. Arantza ease my worries about my procedure. I personally find intolerable setting appointments either for a clean up or root canal. But finding Glendora Smiles change my ways and find myself at ease setting up appointments.

Maria B. from Rialto, CA (Source: Yelp)


I am came in as an emergency and I was seen right away. They replaced my crown which was completed in the office. I was so glad it was all fixed the same day. I was very surprised to receive all of my options of what my insurance offered. Mariela was very helpful and informative of the different crowns they offered. Thank you so much Mariela for making my visit easy

Leslie B. from Wildomar, CA (Source: Yelp)


My kids and I have been coming here for our routine check up and cleanings. My kids like the office and Dr. Lee  shes really caring .  The office is modern and spacious. Karla has been really friendly and nice with my kids they love her. We are very happy with their service. I give this place 5 stars!!!!!

Chris W. from Claremont, CA (Source: Yelp)


Dr Lee and the others at the office are great. I often feel anxious about visiting the dentist, and when I first started going there 3 years ago the whole staff went out of their way to ease my anxiety and just were really nice- and they still are! I was there for a cleaning and doctor visit today and Carla, who did my X-rays, was so warm and friendly. Nancy, the best hygienist ever, puts up with my whining and nervousness and does a great job cleaning my teeth. And Dr Lee and the rest of the staff, including the front desk folks and the woman who handles the insurance info, say hello every time  I’m in the office. And, since I keep going back for My regular visits, my teeth are doing well and the whole dentists situation makes me much less anxious.

Angel R. from Fontana, CA (Source: Yelp)


I went in today for my first appointment terrified to say the least! The gals in the front could tell and tried their hardest to make me feel comfortable…thank you! I met with dr lee and had my X-rays by Rachel sorry I was so difficult and thanks for putting up with my small mouth! I have good insurance but they only cover so much…the young lady who went over my benefits was so nice and patient with all my questions. This time I was on my own with out parents help. Yes I was there for long time but perfection takes time I’m always in a rush and it was nice to be able to get my work done even if I was there a long time at least I was surrounded by nice people! I walked out smiling!! I would of never thought I would be this happy about going to the dentist thank you so much I will be back in 6 months;)

Danielle B. from Claremont, CA (Source: Yelp)


When I walked into Claremont Modern Dentistry I was greeted with a warm smile and an invitation  to drink some coffee and/or eat a bagel with cream cheese. I was encouraged, supported and comforted by all of the staff from the beginning to the end of my experience. They were professional, caring and friendly and the treatment I received was exceptional! When I walked in I was nervous and by the time I left I had been put completely at ease. I am so grateful for the treatment and services that I received!

Yoni T. from Montclair, CA (Source: Yelp)


All of the staff are first class. I was in dire need of major dental care and they took great care of me. A very relaxing atmosphere with top notch services. I cannot recommend them highly enough. Simply amazing! Sweet genuine people. Dr. Soojin Lee and her staff are so helpful and informative. I’ve been screwed left and right from my new insurance and the doctors taking my insurance. But Dr. Lee has been so sweet and informative in explaining to me what is covered and upfront of how much everything will cost. She has taken good care of me and my teeth so far I got a few more scheduled deep cleanings with her and look forward to seeing her and you funny assistant who makes me smile. She has also referred me to an Ortho who’s staff also seems very friendly and helpful as well, she also took the extra step to make sure this Ortho was in my insurance network to make sure I wouldn’t have to worry about those unexpected cost or surprises you get when it comes to insurance. They are also very good about accommodating to your schedule and I never have to wait.

Rob I. from Glendora, CA (Source: Yelp)


As much as I dislike going to the dentist, the staff in this office make it way more enjoyable. Dr Lee is amazing. Have had to go through several visits in the last couple years and have not had a bad experience yet. Entire staff is great!

Angie L. from Loma Linda, CA (Source: Yelp)


I had my implant crown done by Dr. Lee here and it was the most painless, efficient process. She calms your fears and walks you through every step. I have had other implants done but I usually had to wait at least a few weeks while the crown was made in the lab. I had it finished in a few HOURS!! Dr. Lee is personable and honest. She know what’s best for your health and she really cares. She’s the best!! Thank you, everyone, at Claremont Modern Dentistry! I have referred all my friends and family here!

Angela H. from Plano, TX (Source: Yelp)


I recently moved to CA and while in search of a great family dentist whom I can trust will provide the best dental service I remembered Dr Lee at Claremont Modern Dentistry. She took great care of me during an emergency visit while I was on vacation and coming back reassured me I am definitely in great hands with Dr Lee and her staff. Although there’s a dental office down the street from my house I will make the 30 min drive to see her because she values my time and is efficient. I will definitely be bringing my whole family here.
