Dianne S Chun, DDS, MSD

Definitely the best orthodontist in Fremont!!! :) I previously had a consultation with several other orthodontists in the area, but had not felt comfortable working with the doctors and their staff. However, at Dr. Chun’s office, I felt very welcome and actually excited to get braces!
Throughout treatment, Dr. Chun patiently answered all of my questions and explained why each step in treatment was important. She was very professional and friendly, and it was really clear that she definitely knew what she doing.
I finished treatment a little while ago, and am very happy with how straight my teeth look! People always compliment me on my teeth and I always tell them it’s Dr. Chun. Trust me, she’s the best and I would definitely recommend her! :)

VERY EXPENSIVE. The price is ridiculous compared to other dentists. My suggestion, check other places before you commit. Their service is not that exceptional either. Dr Chun rushes through appointments.

So proud to be a part of Dr. Chun’s team for 13 years and counting. As an employee, she’s the best boss ever. As a patient, she’s the best orthodontist in Fremont… caring and only wants the best for her patients. Visit our website at
and see what our other patients (children, teens & adults) say about Dr. Chun and our office.
Thank you Dr. Chun for everything that you do and for making my smile look great! :-)

I can’t even say how much Dr Chun has helped me out in my treatment with braces. There is nothing i can say is bad… from easy scheduling appointments to how nice the staff are. They are very professional and knowledgeable and honest people and great help. Now my teeth are straight and perfect. I would recommend people who needs braces go to Dr. Chun’s office it will be done correctly with great service.

I am on kid #3 with this orthodontist. I love everything about Dr. Chun and her office: Great staff, values your time by being on time, knowledgeable and friendly. Down-​to– earth and really cares about her patients as people. I love Dr. Chun!

Dr. Chun was recommended to me by a family member who has had good results with her treatment. I recently had a consult with her, and it turns out I don’t need any orthodontic treatment, but I’m giving her five stars because the 30 min consult was FREE, and she did such a wonderful job explaining my options. She is very knowledgeable, honest, and charges a reasonable price for treatment (from what I’ve heard). If I did need braces, I would definitely have them done by her.

Both of my kids had Orthodontics there. They started at about same time although they are 7 years apart. You may wonder why? My young one has pretty good teeth except under bite. Dr. Chun recommend 2 phase treatment for her and each cost nearly $ 5000. To me, the 2^nd phase doesn’t seem necessary if she can fix a fewer minor misplace («easily» as Dr. Chun said) together while correcting the under bite.
I have an odd feeling about this office really. Just a month ago during my old kid office visiting, they noticed a crack on his retainer and want to fix it and there is only one way to do it! He needs be back in a week to fit it knowing my old one will be away at college,. I really don’t’ think there is no other option other than he has to come back to fit it. That means hundreds dollars flight ticket. «What is the consequence?» i asked, Well, as they put, your treatment will affected. Yeah, there is contractor they make you sign at the beginning. I wonder how many of you actually read and understand it?
Now, they want to reschedule my old kid appointment again knowing this is the only week he’s back from college for spring vacation. The reason for rescheduling? «Dr Chun will be on vacation this entire week», as front desk put. Well,

Dr. Chun is the best ortho hands down. I refer her to several people and they all got great results as well. I haven’t been in her office for the past 6 years but i started going to her since i was 6 till i was 16. From what i remember she explains things really well and she makes sure that the parents are involved as well. If you need an honest, professional, sweet, and good ortho Dr. Chung is the one for you.

I had her as my ortho back in high school. Must I say, her and her staff are the nicest people. I used to go get my bands changed once a month and they would see me once I get there. They were always on time with their appointments and took care of my teeth to make it look straight. After getting my braces off, people were amazed on the outcome of her work. She is a great orthodontist who obviously has a lot of skills.

12 years later, I still get compliments and people still think I wear dentures! Dr. Chun is awesome! She just makes you feel so comfortable.

I love love love love everyone at Dr. Chun’s office! I got my braces back during my elementary years and I’m now finishing up my freshman year of college and still with her with straight teeth! Dr. Chun is a true professional in her field of work. She’s worked on my teeth for years and made sure that they became perfect! Her staff makes the experience even enjoyable! They are very welcoming and makes sure you are in good hands! I’m so glad that I chose her as my ortho back then because I feel confident that my teeth were in good hands and now I can smile big without a worry! Don’t even think about it, go down to Dr. Chun’s office and make an appointment asap! You wont be disappointed =)
