PATIENT REVIEWS

Dr. Joy aNd the front dest were extremely helpful and friendly. They were on time and the doctor wasn’t rushed at all. She took her time and was very thorough for my cleaning as well as answering all of my questions about orthodontia. I would highly recommend!!

I have found Dr. Sinajon to always be prompt with appointment times and she has consistently displayed  professionalism and a friendly manner. I would highly recommend her dental services.

I moved to the area a year ago and needed to find a new dentist. I have very sensitive teeth & not a fan of going to the dentist. I looked around for a while and decided to go with Dr Joy. From the moment I walked in she treated me like I was her friend! Her assistant Margo is such a sweetheart & loves to get to know you! They are by far the best dentist team I have ever had and i will continue going there and recommending them for a long time! Thank you Dr Joy & Margo for always making me feel welcomed, answering all of my questions & being so gentle with me! Ed – you are awesome as well!

My wife and I just had our first visit with Dr. Sinajon. I found her on Yelp based on reviews and wow she was awesome. Her staff is friendly and polite and I just had the best cleaning in a long time. No pain and the fact that they go out of their way to make you comfortable makes the process of dental work much easier. A quality office with a gentle touch. My family is sold on her service.  Highly recommended

I have had several different dentists work on my teeth in the past. Dr. Joy is by far the best I’ve had to take care of the various problems I have. She’s a perfectionist to a fault and cares very much for her patients and strives to have each of her patients satisfied with her work before they leave her office.
I always look forward to my next visit

Dr. Sinajon really cares about her patients and has so much wonderful integrity that I actually see her for some of my dental needs even though she isn’t within my insurance’s network. Believe me, I would switch to her as a regular patient in an instant if it was. She is the most honest, genuine dentist I’ve ever met. Other dentists tend to overcharge WAY more for their practice, but Dr. Sinajon really puts your needs first and never charges more than necessary. Of all the dentists I’ve ever seen, Dr. Joy is by far the best!!!!

We call her Dr. Joy, her full name is Dr. Joy Sinajon and she is a Joy to us for our dental care! She has been a fabulous caring gentle dentist to my entire family. I have given her name out to other friends and they have tried her with rave reviews also. She did both of my sons orthodontic work.  My older son as he grew up, traveled back from Utah just to see her.  What I love is that she really cares and helps you to understand and be informed about any dental needs or options.  She has been our family dentist for about 10 years! Her decorated and clean office is really nice and easy to find in Costa Mesa.

I couldn’t agree more with the people here on Yelp.  There’s a reason Dr. Sinajon gets such a high rating.  She is very smart, super nice, and tells you exactly what she is doing every step along the way. The office is very personal and inviting and miracle of miracles, Dr. Sinajon is actually the person that does the majority of work on your teeth; she does’t just review it after a dental hygienist does all the work. She’s absolutely the best dentist I’ve ever had and I can’t recommend her highly enough, especially if you have Delta Dental.

I had been seeing Dr. Joy for the past year, and I love her work and her staff. I will be seeing Dr. Joy as I just recently got invisalign.  I referred my wife here. Now my wife told me she wants to keep coming to Dr. Joy from now on. She really loved the work she did on her teeth

Dr. Joy Sinajon is as beautiful as she makes your teeth!! Her warm nature is as inviting as her elegant decor and her giggle calms even the most nervous patients. My 10 yr old son is so calmed by her that he will have a filling drilled and filled without any anesthetic at all. (I’m not that brave) Dr. Joy is an amazing dentist who’s work and care for my teeth has compliments frequent enough, that I now have learned to just say thank you and not blush

Let me first say, I don’t EVER leave feedback for anything, but I felt the need to here.  I went to “Dr. J” yesterday to get my first cleaning and exam in over 7 years.  I mainly avoided the dentist because lets face, we all cringe at the thought of those drills and sounds on our teeth, and the overall discomfort of the situation.  Well, I’m pleased to say that is no longer an issue here.  This was an amazing experience top to bottom.  Dr. J welcomed me right when I walked in the door, and introduced herself.  Right away it felt like a personal experience.  She was involved in the whole process.  It’s almost like having your mom clean your teeth.  She is so personable, and explains EVERYTHING to you that she’s doing and is very gentle.  My fav part was the lil camera she used to show you the before and after pics of your cleaned teeth.  It’s an amazing difference.  You WILL NOT find a better dental experience anywhere.  I even told her that I might have to fly in from Texas every six months just to see her when I move home.  Simply awesome!

I found Dr. Sinajon on yelp after miserable experiences at other dentists, and I’m so happy I did. She’s friendly and really treats you like family! I’m most happy with her honesty which is why I have left other dentists. She has gone out of her way to make sure insurance would cover things and only does procedures you really need. What more can you ask for? The office is nicely decorated and her staff is great, which takes the anxiety out of going to the dentist.  I am two months into my invisalign treatment and I can’t believe my results already! I am so happy and can’t wait to see my finished result! If you are in search of a honest and wonderful Dentist or need invisalign, this is the place to go!

Dr Sinajon has been a wonderful wealth of knowledge and the nicest dentist I have ever met. She is always walking me through exactly what she is doing and what to expect next. Dr Sinajon makes me feel extremely comfortable and makes the dentist visits enjoyable. She makes me feel comfortable and reminds me of my own mother. I made a mistake and showed up on a saturday when they were closed. Dr Sinajon said that she would show up no matter what. That is professionalism at its finest. My wife and I both go to Dr Sinajon and I would reccomend her professional services to anyone. And if you want invisalign, just ask and she will walk you through the entire process. Don’t ignore your dental health!! Call Dr. Sinajon

Dr. Josephine made, what is usually for me, something unpleasant into a wonderful experience. She was thoughtful, gentle and very professional. She is also compassionate and just an all around giving loving person. Thank you Dr. Josephine!

I have a legit fear of the dentist and dread going even if it’s just a simple cleaning. After putting off my appointment for a long time, I finally decided it’s time to get my teeth checked out. Dr. Sinajon was referred to me by family members as they all raved about her gentle yet thorough techniques. While getting your teeth cleaned is never fun, she did an excellent job and my teeth feel brand new! Dr. Sinajon definitely has a great sense of humor and told me to stop “white knuckling” it during the cleaning haha. I will definitely be seeing her on a regular basis and so happy to finally find a dentist I can trust!

Dr. Joy is a godsend. She was recommended by a friend after having horrible experiences with dentists who just want my money.  Dr.Joy is the complete opposite. She cares about her patients and always gives thorough explanations of what she is doing. She has always tried to provide me with the least expensive but best treatment option. Her assistants are extremely personable, friendly and helpful. The office is nice and welcoming. I couldn’t be more pleased to have found Dr.Joy

Excellent service. I was scared to find a new dentist. Especially just going to the one closest to my house.  This dentist is a gem and her office is very clean and up to date with the equipment. I came in for an emergency with a chipped tooth and I will be coming back! I have a new dentist! Couldn’t be happier

I was looking for a dentist in my area and came upon this gem.  I’ve been to a few dentists before this and I can sincerely say that Sinajon is the best I have experienced this far in my life.  She and her staff treat you like family.  She showed me using a mirror what my teeth looked like before and after like after a haircut.  Most importantly they make the experience pleasant and comfortable!!  I would recommend to all of my friends and family!!  Coming back every six months!!!  Highly recommended!

Dr. Sinajon is a wonderful dentist. She’s very friendly and knowledgable. She typically walks you through the whole process while you are getting your teeth serviced, which is a nice plus so you can be at ease. Overall she’s a great dentist and her staff is also above par

Dr. Sinajon, or Dr. Joy is definitely THE BEST dentist I’ve ever had. I had issues with my teeth and bleeding gums.  I went through five other dentists and orthodontists before I met Dr. Joy.  The other dentists and orthodontists knew I had bad gum issues, but they saw me as “dollar signs” rather than trying to provide REAL solutions to my gum issues.  Dr. Joy was the first dentist to really think of me as a patient rather than $$$.  She is very personal and cares for her patients as human beings. I can’t begin to describe how much dental work I needed, but Dr. Joy was there through my every ortho and surgery phase.  She treated my case with perfection and great attention to detail.  Even the specialists she refers me to are wonderful as well.  I now have a perfect smile with much healthier gums.  I credit all this to Dr. Joy.   Overall, her office is clean and welcoming.  The staff is fantastic and very friendly.  I actually like going to my dentist because Dr. Joy has made dental visits a fun experience

Delicate hands, prestine environment, warm technicians and an inviting front office staff are a cornerstone of Dr. Jo’s dental practice. I’ve been seeing Dr. Jo for several years now and most recently, when my job changed insurance providers i based my decision on which option to exercise based on which one offered continued access to Dr. Jo. I feel like family when im there and would recommend Dr. Jo to those seeking a great experience and a great smile! =D

Dr. Sinajon is the BEST DENTIST I have ever been to! Her practice is located in a hidden shopping center of Harbor and Mesa Verde in Costa Mesa.  She is the sole dentist in her office, so you definitely get personalized, one-on-one service.  The inside of the office is very quaint and welcoming; very atypical for a dentist office!  Another cool part of her office are the massaging dental chairs…very RELAXING! All in all, going to Dr. Sinajon’s office is a very enjoyable experience.  The Dr. is very warm and personable, and you can tell she cares for each of her patients and loves what she does.  That alone is the reason why she will be my dentist for life

Dr. Sinajon is by far the best dentist I’ve had here and abroad. Great staff and awesome service over all! I don’t have to wait for a hygienist because she’ll do it herself. Super light hands and it feels like she really does care for her patients and not just in it for the money. I’m glad to find her here on yelp.

I have used Dr. Joy for at least 10 years or so.  She has gone the extra mile for me, one Sat. I lost a crown eating something I should not have been, I was 2 hours away, she waited for me to return home from the mountains and took care of my tooth that Sat. afternoon. She really cares for her clients, I have my whole family going to her.

What a great dentist. I have seen a number of dentists in the Costa Mesa area over the last 30 years. She is patient, caring and has always been able to see me in an emergency. No upsell or other BS many dentists seem to sell. I have refered my family, friends and co workers and they have all been as pleased as me. Her fees seem very reasonable. Dr Joy is a pleasure and I hate dentists, but not her! Thanks for the clean teeth, I apprecaite your attention to my issues

Dr. Sinajon is hands down the best dentist I have ever been to and has provided the best dentist visit experience yet. Firstly, she is extremely organized, clean, and professional.  She definitely knows her stuff when it comes to your teeth and will not cut corners when it comes to your treatment. Think about all of the times you’ve gone to the dentist only to have the same tooth need some time of work again at a later date because the dentist was lazy and didn’t want to be as meticulous as your teeth deserve!! Dr. Sinajon truly cares about your teeth and overall oral health and will work to make sure your teeth look absolutely perfect! That was my experience with her. She is also extremely nice and welcoming. Her office has this warm feeling to it and I felt comfortable sitting in the chair for a long time. I felt complete confidence in ever drill movement because she explained the work as she went along, and reassured me that the moment I felt pain to let her know and she would take care of it. Also, I was interested in purchasing invisalign. She walked me through the process and possible fees. She even showed me examples of previous patients who needed similar orthodontic work and the result that occurred with their invisalign treatment
