(…) My wife and I have been seeing Dr. Lee for more than 5 years now.  For all my visits, he performs his procedures rapidly and painlessly.  He does not talk a lot but he listens and addresses all my concerns without any rush. And most of all, this guy is really honest.  With the way insurance treating dentists these days, you can get easily ripped off or get unnecessary treatments.  You would never get that from Dr. Lee. If you want a dentist who gets the job done fast, painlessly and honestly, I highly recommend Dr. Lee.

(…) My fiance recommended Dr. Lee after I moved to Fullerton last year. She was right about this choice (as she is on most things). At A’ Dentistry, you will be greeted respectfully from the moment you call for an appointment. The office cleared my insurance before I even arrived for the appointment. I had X-Rays, a check-up, and a cleaning completed in under thirty minutes. Dr. Lee does not waste your time, whether you are in the waiting room or in the chair. He is efficient, caring, and will direct you towards taking better care of your teeth. I look forward to continuing my dental health care with Dr. Lee and A’ Dentistry.

(…) I called yesterday morning right at 9 am and the Receptionist answered right away. It only took a few minutes for me to explain why I was calling and before I knew it, I had an appointment set for 11 am which was only 2 hrs later. I wasn’t expecting to be seen so soon! I was very thankful that they could see me right away! Overall, my appointment was quick and efficient and I left the office really happy that I was no longer in any pain because of Dr.Lee and his staff making my experience so enjoyable. Thank you Dr. Lee & A’ Dentistry Staff : ) You Rock!!

Dr. Lee has been my dentist for close to 10 years. I’m not an easy patient 10 years ago I was a little baby and I hate needles (and till this very day I despise).  Dr. Lee is a great dentist and is also caring.  I moved to San Diego and i drive all the way up there to see him. Highly recommend him and his office staff is GREAT.

Dr. Lee is the best dentist in Orange County. He is extremely friendly and knowledgeable. I HATE going to the dentist but Dr. Lee makes it so much more bearable. His ‘technique’ is phenomenal. I have come here for cavities, cleaning, and even pulled out a simple wisdom tooth. I highly recommend Dr. Lee to everyone looking for an amazing dentist.

Outstanding dentist who truly cares about your tooth pain. I was very impressed with his knowledge and skills. Clean office and nice staff as well!

Teresa S. from Anaheim, CA (Source: Yelp)


Just came back from having cleaning n filling. Last week I had an extraction and I’m still very happy with Dr Lee and his staff of professional caretakers. Dr. Lee is absolutely the best (…). The service is excellent and again Dr Lee explained what was going to occur and even told me what I may need in the future but said. “You don’t need to do that now”. This impressed me so much and I will remain a loyal patient.  Thank you, Dr Lee and everyone in the office. You make a difference in this world and allow me to Smile

I had a great experience coming to Dr. Lee’s office! The staff was friendly, the office was clean, and he did an amazing job. Would definitely recommend his office to anyone. Thanks for all of your help, Dr Lee!

Excellent as with every visit. The front clerk is always nice, and the Dentist gives great service. He always gives the best advice for my dental health and never pushes me to make financial decisions that I am not comfortable. I am happy to say that I finally have a dentist for me and my family.

Miguel G. from Fullerton, CA (Source: Yelp)


Great dentist office, I had to make an emergency appointment on a Saturday for my father and fortunately, they accommodated us. We saw the Dr. within an hour from making the initial call. The Dr. Is kind and a person for and of the people.. I will recommend anyone to him!

Amanda L. from Lakewood, CA (Source: Yelp)


As getting old, I had tooth pain when I have a cold drink. Dr. Lee told me I need a root canal and he did a great job. He fully booked most of the days so it took a little longer to finish everything. But it didn’t bother me at all because I can drink cold water without pain!! Clean office and friendly staff. Dr. Lee is a very honest dentist and very professional.

Wanchart V. from Lakewood, CA (Source: Yelp)


I been seeing dr. John for almost 10 years and he is the most caring dentist. So..I brought my parents and sister here and they were very happy to see how gentle he is. Good follow up as well. If you are looking for a dentist, you found it. Highly recommended.

Francis K. from Irvine, CA (Source: Yelp)


(…) I’ve been to Dr. John Lee a couple of times, and he is very thorough and kind. I hate going to the dentist, but the friendly staff and dentist here made my visit a pleasant experience.

Vanessa R. from Brea, CA (Source: Yelp)


This dentist is amazing! I was recommended by my husband, my boyfriend at the time, and also by my mother-in-law. I was going to a different dentist at the time and wasn’t too happy with them. They wanted to do two cavities on me and I was a bit shocked because I take care of my teeth. My husband told me to go to A’ Dentistry. I called to set an appointment, the receptionist is sweet. She worked very well with me. I emailed her my x-rays from the previous dentist. She had Dr. Lee take a look and figure things out. He said I didn’t need any work done. But I was due for teeth cleaning which I set an appointment for. I then referred my mother. My family and I are very pleased with this dentist. No matter the distance, we are willing to drive because they are great!

Hyunhee K. from Fullerton, CA (Source: Yelp)


If you are looking for a great dentist, Dr. Lee is the man for you. My whole family has been going to Dr. Lee for a couple of years now, and each experience has been the best I have ever had. He is honest, kind, caring, and gentle, and, both he and his hygienists are always very professional.  From the moment you walk through the doors of their office (located in Fullerton), you are greeted with a very friendly, warm and inviting environment and extremely wonderful service by Rene, the receptionist.
Look no further for a great dentist than Dr Lee,  If you have to trust someone to work in your mouth, it may as well be him. You will not be disappointed.

I have always hated going to the dentist until now. Dr john lee was very professional and made me feel very comfortable. The staff there is very friendly. The front desk receptionist made me feel at ease and assured me that the process would be easy and painless. Which it was! Lorena was great also! Everyone made me feel like a million bucks! I would definitely recommend coming here. I can’t wait until my next appointment!

Sandra E. from Anaheim, CA (Source: Yelp)


Dr. Lee is a great dentist.  I was formerly a dental assistant myself and I know when a dentist is good and Dr. Lee is very good and kind!!! The office is very clean, well decorated and modern.  The staff is wonderful and is always very flexible with your schedule and they never make you feel uncomfortable.  Please try this office you’ll love it!!

Adrian A. from La Habra, CA (Source: Yelp)


My service here was EXCELLENT! The appointment wait time here is great. I called for a routine cleaning and was offered an appointment the same day. I didn’t need it THAT soon, but it’s good to know that this office is easy to get in for those emergency cases! Everyone is polite, wait time is not long at all. Office is clean, neat & beautiful. Dr. John is awesome! Did a great cleaning job, I will definitely be coming back.

(…) By appreciating his sensitivity to customer dental needs, we recommended his services to our 72+-year-old mom.  She appreciates his kind manner and professionalism. Dr. Lee consults with you on a problem but not be a pushy salesman. His prices are more than reasonable and his accommodations are quite comfortable. Although i choose to read a book instead of watching a movie, it’s nice to know that customers have the option.

My anxiety over dental procedures is off the chart because of so many awful experiences. My appointments with John Lee were a great relief. His dental team is respectful and professional. His experience speaks for itself, and you don’t have any surprise charges to stress about. I appreciate the professional office staff and the text alerts for my appointment time. I highly recommend him and the entire staff.

R. M. from Garden Grove, CA (Source: Yelp)


Once again, Dr.Lee and staff prove they are the best in the field. updated patient info,Xrays and tooth extraction and i was out of there in 20 minutes. another pleasant and pain-free visit. I am proud to consider Dr.Lee as my personal dentist…Thank you Dr.Lee and staff.

Justin O. from Los Angeles, CA (Source: Yelp)


I have been to Dr. Lee’s office last year and yesterday. I have always been afraid to go to a dentist. Dr. Lee is a fable guy and makes me relax while treating my teeth. I hardly felt any pain. I just wish I see him as often before I have any dental problems.  The office staff are super nice too and always greet patients with big smiles.
Thank you Dr. Lee.

Valerie L. from Fullerton, CA (Source: Yelp)


Dr. Lee has been my trusted dentist for about nine years now and I highly recommend him and his staff. Dr. Lee is patient and understanding. His team is always so friendly and caring. What I appreciate the most is that their service is painless and quick. The icing on the cake is that they’re also open on Saturdays!!

Edward Y. from La Mirada, CA (Source: Yelp)


Wonderful and professional service. He is a nice man who has a warm heart! I have been visited several other dental offices to fix my denture. Every time, I have been disappointed because of their high estimated price. I couldn’t afford to fix it.  He just made it for me only at (a great price) and it is a perfect fit. I don’t know how to thank you enough!. Thanks again.

Always consistent in great services. Dr. Lee is honest and trustworthy. He takes pride in what he does and provides great care for his patients. I’d definitely recommend to others and family members. His team members are very respectful as well.

Adriana M. from Fullerton, CA (Source: Yelp)


I was scheduled the very same day and I was in and out in 30 minutes. The staff was very friendly both over the phone and in person. Dr. Lee is very pleasant and he made sure I was comfortable through the whole procedure. He cares about his patients and it shows. I was a cash patient and they charged me (a great price). I definitely recommend him!
