Dr. John transformed my smile completely. I used to be embarrassed of my smile until I met Dr. John. My family and friends are loving my new smile. I never wanted to take photos smiling until now I can’t stop smiling. Dr. John is really outgoing and smart. Everyone in the office is really nice. Liz in the front helped me schedule an appointment and with options for payment plans. I was happy to find out how easy and affordable it was to come visit the dentist. I highly recommended Dr. John and his staff to all my family and friends he is the best dentist I have ever been too. Thank you Dr. John and staff for improving my smile!

We started going to Dr. Nguyen about six months ago he is very professional and super nice. I took my son there because he was highly recommended by a friend. My son as a child had a very bad experience but Dr. John made him feel comfortable and he was so patient with him. His office is clean and all his staff is great. Now our whole family are patients with Dr. Nguyen.

I can’t say enough about this office. Took my 12 yr old son for a exam and Dr squeezed him in for a cleaning and sealants. He was so mindful of our time and values his patients beyond the normal. My son will only go to him now. He is cavity free and can’t wait for his next cleaning.

I needed a dentist as a new resident of Costa Mesa. I found Dr John Nguyen in my provider registry and really hit the jackpot. I have never had a cavity or lost a tooth before and my far back molar was loose due to bone loss and needed to be extracted. This required numbing shots in the mouth which everyone warned me would be awful. Dr Nguyen has such a relaxing demeanor and is so friendly, he really took time to get to know me on my first visit. When he did the extraction, I needed four or five shots and didn’t feel even one of them!! This was a painless and amazing experience. His office staff and hygienist are all friendly and professional and I couldn’t be more pleased. If you need a dentist, do yourself a favor and give this one a try.

First of all I HATE going to the dentist. I mean who does right?!??
BUT ever since I’ve met Dr. John he has made me change my mind! I love going to the dentist now! He is super down to earth and has the best vibe ever. He makes you feel like you aren’t even at the dentist office.
Everyone here is really friendly too and honestly makes your visits worth coming to. Liz in the front is super friendly and helps me understand my insurance benefits which is awesome because I do not know how insurance work.
My hygienist Halyna is super nice and plays my favorite music while having my cleaning done. I’m so happy my friend recommended me to Dr. John! 😀  I am for sure going to let anyone know about Dr. John and his office.

Dr John is super friendly and greeted my husband and I when we arrived. The staff are nice and professional. I was able to make two appointments same day for two teeth cleanings. I feel like I received a quality cleaning. The staff and experience we’re great. Thank you Coastal Family Dental!

Christina M. from Costa Mesa, CA (Source: Yelp)


GREAT DENTIST! My husband was having a toothache so I called and Amber scheduled us to come in that same day! Turns out my he needed to have a root canal done, dr john was able to get him out of pain that same day and they scheduled him in a few days later to have a root canal. Vanessa, the assistant called me the next day to see how my husband was feeling and made sure we had no questions.My husband is pain free and his tooth is beautiful! 🙂 The whole process was so smooth and easy! I really feel a sense of happiness from the moment i walk in the door. I would definitely recommend Coastal Family Dental!

Erik D. from Santa Ana, CA (Source: Yelp)


Dr John & his staff are awesome!

I went into his office the other day and everyone is very friendly.The appointments always go very smoothly.
Their schedule varies so there are a lot of open times for you to pick from that some other offices don’t. Also they are open some Saturdays which helps!
I went in for a cleaning with the hygienist Halyna and she did a phenomenal job, she’s great! She is really outgoing and puts on your favorite music while doing your cleaning.

I’m happy I am starting my Invisalign treatment here. They have the best deals and highest technology! I highly recommend Coastal Family Dental!

Richard U. from Costa Mesa, CA (Source: Yelp)


My whole family comes to Dr. John. The staff is very friendly and they make setting appointments and reminders easy with text updates. They do great work and make trips to the dentist dare I say enjoyable

Karen R. from Lake Forest, CA (Source: Yelp)


Dr. John is the best dentist my family has ever had. My two sons don’t even complain about going – and that is a first. The cleaning is excellent – my teeth have never looked or felt better. Appointments are easily scheduled and they send timely reminders. Five stars for this Dentists Office! Karen Ruan, patient and fan

Professional and caring service. Halyna does a great job cleaning my teeth. Dr. John likes to chat and makes you feel very comfortable. Appointments are easy to make, they are on time and don’t make you wait.

Freddie B. from Costa Mesa, CA (Source: Yelp)


Dr. Nguyen is the BEST dentist I’ve ever been too! I’m so happy I called and made the appointment. It’s been so long since I’ve been to dentist. I was always nervous to go back. Luckily, Elizabeth made it so easy to make an appointment. She was very detailed and super outgoing! The dental assistant Stephanie was also really friendly. Dr. Nguyen is super down to earth and easy to talk to. First dentist I can actually trust with my dental needs. Everyone here makes you feel like family.
I didn’t even have to wait at all to see the dentist I was seated right away! I highly recommend anyone who is looking for a dentist come to see Dr. Nguyen and his crew! (:

Dr John is super friendly and greeted my husband and I when we arrived. The staff are nice and professional. I was able to call ahead and make two same day appointments for two teeth cleanings. I feel like I received a quality cleaning. The staff and experience we’re great. Thank you Coastal Family Dental!

Dr. Nguyen is the best. I had been really anxious about going to the dentist for years because of a really horrible experience with one when I was younger. Then I met Dr. Nguyen and he was so friendly and kind, it really put me at ease. I’ve been going to him for a couple years now and every time is great. His team keeps me on track for cleanings and he has done great work on my teeth. I highly recommend scheduling an appointment with him, if you’re looking for a great dentist.

Shelly S. from Orange, CA (Source: Yelp)


My son and I just started going to Coastal Family Dental. Dr. John Nguyen is so kind and great with kids. Everyone that works in his office is inviting and makes you feel comfortable. He was gentle, kind, understanding, honest, and I really enjoyed his cool office atmosphere. Thank you for being our new family dentist Dr. John and Team.

Dr. John is the best! I just had my check up and he made my tooth look so much cleaner! Dr. John is very informative and kind. His assistant Juan is gentle and kind too! All the staff there are nice and happy. Strongly recommend!

Elizabeth S. from Costa Mesa, CA (Source: Yelp)


I just finished my Invisalign and I am loving the results. Dr. John did an amaaaaaaazing job. I am so happy I found this dental office. Everyone is friendly and makes you feel comfortable from the start. I recommend everyone to come to this dental office you will not regret it ! (:

I’ve been going to this place the last 2 years, and they’re amazing. The staff is always nice and helpful. I get a little bit of anxiety going to the dentist, they offer to play music during your cleaning which helps. Just got my teeth clean yesterday and they feel so good! Definitely recommend this place to others.

Dr. John is the best Dentist in all Orange County! He listens to your concerns and does amazing work. I just got finished with my Invisalign treatment here at Coastal Family Dental not too long ago and I get so many compliments on how beautiful my teeth are. 😀 The Hygienist Halyna also does an amazing job in cleaning my teeth. She also educates me and leaves my teeth looking really white! (: Halyna always puts on my favorite music during my cleanings which definitely take the ease off. The staff definitely treats you like family and are really helpful with any questions you have. I used to hate going to the dentist but now I’m always looking forward in coming to my appointments! (: If you are looking for a new dentist definitely make an appointment. The staff and Dr. John will really make your dental visits more comfortable. My whole family and friends come here now.

Amazing staff, clean and warm facility. I can’t say enough about Dr John and the team. They play awesome music and you forget your even at the dentist office. My kids go here and I refer any that is looking for a honest, caring Dentist and hygienist.

I had chipped a tooth. We had heard good things about Dr. Nguyen, so I called Coastal Family Dental the next morning, and Elizabeth scheduled me to see Dr. Nguyen that same day!
Dr. Nguyen took me in immediately after I arrived. The work he did on my tooth was outstanding, and the whole staff was very friendly and efficient. Also, the cost was very fair.
My wife and I will be using Dr. Nguyen from now on.

Lyly N. from El Monte, CA (Source: Yelp)


(…)No wait time at all! They were ready for me on the dot! I forgot the assistant’s name who took my X-ray, but thank you! You were funny and sweet!
Dr. John explained thoroughly the condition of my teeth and procedures that he may be doing, but, of course, he wanted to as little as possible to save me time and money! (baby teeth & wisdom teeth present and options for them). He was very genuine, honest, and transparent!

Halyna (hygienist) took her time cleaning my teeth and explaining what and why she was doing it. She made me feel more knowledgeable about dental care. Of course I couldn’t talk, but she kept entertaining me with funny patient stories. Thank you for that!

Sara G. from Costa Mesa, CA (Source: Yelp)


I have came here twice and I can honestly say I love it! They make you feel comfortable and make sure to explain the procedure step by step.  I like to ask questions about everything just so I can get a better understanding about what’s going on in my mouth and Halyna answered every single one in detail and made sure I understood. She and Dr. John are so nice and always made sure I was ok.  The whole staff from the office manager to the dentist assistant were friendly and go out of their way to make this experience a great one.
Will definitely be coming back and I highly recommend this plac

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


Wow, where do I begin! I just finished my Invisalign treatment and wow my smile is amazing ! My experience at this office has been nothing short of amazing! (…)

Dr. John was super personable too! He also took his time to make sure I understood the treatment and was comfortable with it. He also didn’t upsell me on anything and was very honest and conservative!

Overall, this is an amazing, friendly office with quality service! I felt like I was here to hangout with friends while getting my oral health taken care of. They genuinely care about their patients! I have already referred them to my friends and family. Love them!

Maria G. from Orange, CA (Source: Yelp)


Not going to lie not my favorite place to visit (the dentist)…the staff and service they have has changed my mind. The staff is very attentive and  friendly they get to know you by name which means a lot working in the hospitality industry.  The treatments I’ve had done have been 100% to my standards. I definitely will recommend to my family and friends which I have .

Dr. John and Halyna are one of the best and the receptionist is amazing as well.

(…)I am a teacher in this area and I broke one of my back teeth early in the morning. My normal dentist was closed and my tooth was throbbing. I was just calling anyone near me. This office had me in and out in no time! (…)my insurance didn’t cover the services, but they gave me a more than fair bill. I’m scared to death of going to the dentist but the staff and I laughed the whole time. The Dr. was very patient and caring. I can’t wait to get my whole family in here. I was so happy and satisfied that one of my co-workers are now going to change to this dentist. (She has a phobia of dentists.) So happy that I stumbled across this wonderful practice!!!! Thank you so much for your kindness, compassion and caring!

I went for a teeth cleaning and check up since it had been years since I had been to a dentist. Elizabeth at the front desk is so awesome and friendly, Marissa the hygienist was so sweet and light handed and made sure I was ok throughout my cleaning and Dr. John Nguyen is so easy to talk to and explained everything. He really cares about his patients and understood money is tight. He didn’t try to upsell and just really wanted to help. I voiced my interest in Invisalign and they gave me a free consultation. The whole office is awesome. I would definitely recommend.

P.s. I don’t have dental insurance and their rates are more on the affordable side with great service!

I used to hate going to the dentist but everyone at Coastal Family Dental is amazing!! Haylena is the best, she makes you feel as comfortable as possible during cleanings.

Elizabeth G. from Santa Ana, CA (Source: Yelp)


(…)Dr. John is a genuine dentist very outgoing and he is always stays up to date with us. It always feels like I’m visiting a friend he is super down to earth and funny.
The hygienist Halyna makes my smile super shiny clean. She always puts on my favorite music while she does my cleaning. She’s always making me laugh with her funny stories.
The front desk Liz is really friendly and takes care of my insurance so I don’t have too. Joanna the assistant is super cool too.

Overall I’m glad I found this office and I’m definitely staying with them they make everything go by as smoothly as possible. Dr. John is a great addition to our community. (:

Crissy A. from Santa Ana, CA (Source: Yelp)


Love this dental office!(:

Everyone is super friendly and makes you feel like family. Dr. John is super friendly and very knowledgeable. He makes sure to go over exactly what you need. Liz in the front made it super easy for me to make an appointment. Joanna took my xrays with a high tech machine that did not require sticking a tool in my mouth. I am starting my Invisalign here and I am really excited.(:

Overall my experience was great, won’t be going anywhere else after this!

Cesar H. from Santa Ana, CA (Source: Yelp)


Finally I found a dental office that fits my needs! I am excited to finally start my Invisalign treatment. I have been to many offices but none made me feel comfortable. Dr. John is really friendly and talkative. Halyna the hygienist cleaned my teeth and made them look really white. Liz and Joanna are friendly as well. I already told my co workers and family to come visit this dental office.

Eber G. from Costa Mesa, CA (Source: Yelp)


Dr John , Liz and Joanna rock !! From the moment I entered to the moment I stepped out it was nothing , but a pleasant experience. Dr John takes his time and listens to you. You don’t feel rush. Just found my new dentist. If your looking for a dentist please pay him a visit.
