Josephine Sinajon,DMD

I am so glad my sister referred me to Dr. Sinajon. She’s not too rough on your teeth and she does a great job explaining why and what she is doing for your teeth. She doesn’t try to recommend procedures etc that you don’t need. She’s a fantastic dentist!
Overall, a great experience and I highly recommend her if you are in need of a dentist.

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 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!!!

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 Unilocal

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.

My wife and I just had our first visit with Dr. Sinajon. I found her on Unilocal 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.

My Family told me go to try this Clinic because I was having mild sensitivity in one tooth. They treated me very well when I visited the first time. The people were nice and friendly. But after the cleaning, the doctor told me I have to fix 3 teeth and pay about $ 200 with the insurance. I thought it was weird. I had just cleaned my teeth 3 months before and the other doctor said everything was okay. I take care of my teeth very well every day. I didn’t think I would get so many problems in just 3 months. I tried to visit my dentist friend. He told me it is not necessary to fix everything they said. He said one of my teeth had very small cavities. He said it is better to keep my teeth clean. If I fixed it now, it could be take some of my real tooth out. In the long run, that is not good for the health of your teeth.

Nice service. Linda helped me clean my teeth. It felt like tooth Spa. So comfortable. Doctor Josephine was professional. She also gave me good information how to keep my teeth healthy.

Dr. Joy is the best! She is patient and kind and a very good dentist. For those frightened of the dentist she is the one to see! Plus all her staff is just as nice.
She will also do all she can if you have an emergency situation, even on weekends.
I live in Tustin and still see her (I even saw her when I lived in Fullerton). I am very happy she is my dentist.

Wow! Dr Joy is the most gentle, efficient and overall excellent dentist that I have been to in a very long time. I am not a fan of the dentist but I couldn’t make my follow up appointment fast enough. If you’ve been putting off going to the dentist, pick up the phone now; you will not be sorry!

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.

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

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

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.

Very friendly staff, the office was very clean and the Dr was very through, did not rush and explained everything. He could have told me I needed $ 1200 worth of work I stead he was honest and said it could wait… I will be going back to this office for sure and referring friends and family. It’s hard to find honest people these days and this was a find!
I saw Randall Kunert, DDS

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 décor 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.

Like 97% of the world, I have always had major anxiety about going to the dentist. My teeth are not perfect and I’ve had my fair share of cavities, so I definitely know a thing or two about the dentist.
One of my coworkers suggested Dr. Sinajon (that was about two years ago) and I’ve been going ever since.
1. Dr. Sinajon’s staff is comprised of mostly her family. Everyone is so sweet and her dental assistants are extremely gentle. It makes your experience so much more comfortable. You really come to develop security and trust, which are two things I require in all physicians I come across.
2. Gentle as can be. I’ve never in my life enjoyed going to the dentist so much. Dr. Sinajon is so knowledgeable — but not at all intimidating. She answers your questions in very simple layman’s terms so that someone as ditzy as me can even understand.
3. You get to walk away with pretty much the most amazing toothbrush EVER. The quality is incredible, soft yet sturdy bristles.
4. Décor — I’m a sucker for a nice office. I thoroughly enjoy the seasonal décor, it’s the cherry on top of Dr. Sinajon’s amazingly efficient service.

FINALLY! A DENTIST WITH NO BULLSH! T SERVICE!
After 5+ years of not seeing a dentist (way too many bad experiences), I took my coworker’s referral to Dr. Sinajon. Let me tell you that it was one of the best pieces of advice ever! Awesome staff on hand and very personable as well. She doesn’t try to BS you with upselling and tells you the truth straight up.
I will definitely refer anyone to her!

When I lived in Costa Mesa Dr Joy was my Dentist I really miss her
