Tri-Valley Orthodontics, Dr. Jesse Ko & Dr. Anne Yoon

I received my orthodontics treatment at this office. The office staff (Erin) is very professional and courtesy. Both Dr Ko and Dr Yoon are great orthodontist. My treatment was started and completed by Dr Ko. He was vrry diligent and forthright when it came to my treatment. I had to move out of state toward the end of my treatment and they worked with my schedule flying back and forth. The office was always clean with updated equipment. Family and kid friendly. kids came on many occasions while I received my treatment. the office staff, new medical staff (Alisha) and both orthodontist were always kind and aporachable. I highly recommend this office for your orthodontic treatment.

Thank you Tri Valley Orthodondics for being so extremely patient with my VERY anxious daughter. Their office is meticulous, and their receptionist is friendly and pleasant. Oh, and my daughters smile is just beautiful after getting her braces off! Thanks again so very much! I’ll definitely be using them again for my younger daughter!!!

Dr. Yoon and Ko are both so great I couldn’t have pick a better office! From the minute you walk in everyone is so warm and caring! Very informative and they listen to all your needs! Definitely recommend!

Always super friendly and helpful! Even remembered my birthday :) I have been recieving help for my impacted wisdom teeth and they have been with me the entire process, always giving helpful advice. If you want a friendly and effective dentist i would come here.

I just finished my Invisalign treatment with Dr. Ko and I’m so satisfied with my final result. The whole process was seamless! everyone from the cute receptionist Erin to the doctors were so friendly, professional and pleasant at each visit. Their office is so clean, modern and welcoming that I looked forward to my monthly visits.

Our family loves the entire staff at Tri-​Valley Orthodontics. My 10 year old son went in for an expander and phase 1 braces. Every time we go in from making the mold for the expander, to check ups for the expansion and today actually putting on the braces, Dr. Ko, Dr. Yoon and Erin are so warm and friendly we look forward to going in. My daughter who joins for the visits likes going in to watch the movies they have playing and read the nice selection of books in the waiting room. They go out of their way to make my son feel comfortable and explain the process of what they are doing so he is not afraid. The office is high tech and very appealing to kids, clean and welcoming. I highly recommend this practice to anyone who may have a child who is anxious about starting orthodontics. They go out of their way to make patients feel happy about improving their smile.

I have been seeing Dr. Anne Yoon for Invisalign treatment for the past year, and I have to say the experience has been fantastic. Dr. Yoon is very thorough and had a great chair side manner. She will never push unnecessary treatment and is great at explaining what needs to be done and what to expect. No surprises! Their office is beautiful and serene and they have some awesome art hanging drawn by their patients. I travel from the city to see her and I always feel comfortable and well taken care of there. Dr. Jesse Ko is wonderful as well. I definitely recommend the both of them for all of your crooked teeth needs!

Dr. Yoon is the best! My daughter was one of Dr. Yoon’s first and now I’m going in to get braces… yes, braces for mom! Couldn’t be happier that Dr. Yoon has chosen the San Ramon area to open her new practice! Do not hesitate going in to get that consultation with them, you will not be disappointed!!!

Tri-​Valley Orthodontics and both Dr. Jesse Ko and Dr. Anne Yoon are so great!
1. The Office is so clean and modern. When you walk in it feels so welcoming and warm! Everytime i walk in i feel so energized by all the positive energy!
2. Dr Ko and Dr Yoon as well as the staff are so friendly and caring! They genuinely care and really ask you how you are and want to get to know you!
3. They give a lot of explanation and details in to care, procedures, benefits and treatments. I feel that i understand a lot more walking out.
I highly recommend Dr Ko and Dr. Yoon. They are very professional and really take this journey with you trying to give you the best care and treatments possible!

I was so impressed with Tri-​Valley Orthodontics and Dr. Ko in particular. The facilities are amazing — so pristine and modern — with all of the latest up-​to-​date equipment. When I went to see Dr. Ko for a consult, he was very thorough when discussing all of the pros and cons of each option and discussing expectations. He gave me the information I needed to select the treatment I wanted, without pressuring me into selecting any particular option. And, when we decided on the course of action (which in my case was braces), he was very efficient and he and his office were very good about follow up to see how I was feeling. His office also provided me with useful tips on healthy teeth care and a kit. I would recommend Tri-​Valley Orthodontics and Dr. Ko to anyone. You will really feel cared for as a patient!

Drs. Yoon and Ko are awesome. They are super friendly and informative. They will go over all options so you don’t feel pressured into any kind of treatment other than what you’re comfortable with– which proves they’re not only very knowledgable, but reasonable and understanding. The office is extremely modern, chic and clean with a nice selection of reading material as well as entertainment for distraction purposes. They also have cute artwork displayed on their walls from an art contest they had for children to have a chance to win scholarship money as a prize! Very cool of them. I would recommend them to anyone and everyone for orthodontic treatment. You won’t be disappointed.

Couldn’t be any happier with the service and excellent work done. My daughter had to transfer orthodontist because her initial ortho transferred to a different city. They recommended Tri-​Valley. Couldn’t be happier. Really nice people, and very clean facilities. I can’t recommend this orthodontist office enough.

I normally don’t write a review, but after receiving such an impressive service I couldn’t resist myself. Definitely five stars for this practice! I am impressed with all the work and care Dr. Ko and Dr. Yoon provided for me. They truly treat their patients as if they are one of their family member. They will plan out the treatments that oversee your oral health as well, highly recommend!

I was treated so well by Dr. Yoon, Erin, and support staff, and feel fortunate to have found them. Dr. Yoon is very knowledgeable and experienced, and has a great way of communicating with patients and explaining everything. Highly recommended.

This review is long overdue. My son needed braces and we came to Tri Valley Orthodontics for a second opinion after receiving a great recommendation from a friend.
And wow! This place is NICE!
For me, the draw is the overall service, detailed explanation by Dr. KO (He is not condescending when explaining the treatment as some doctors do.), the welcome by the pretty receptionist AND my favorite cup of Nespresso coffee.
For my son, it is the friendliness of Dr. Ko and the detailed answers he gets to his questions (My son is a curious boy.).
Now, my son has braces, my younger son will be getting one here too and my youngest even likes to ride along during her brother’s visits.
I definitely recommend this place.

Absolutely fantastic office from the second you walk in to the second you leave. Everybody here is so professional, personable and friendly. This is all on top of a beautiful office. Everybody in the office treats me like family which is very much appreciated. I would absolutely recommend Dr. Ko and Dr. Anne for orthodontic treatment!

I had my official consultation today with Dr. Yoon and Dr. Ko. We took X-​rays, teeth impressions and photos. The whole process was really easy and comfortable. When you walk into the office, you’re greeted by Erin who is so sweet and welcoming. The office is really beautiful. It’s all white and very sterile. There are snacks, nespresso machines, water, and just about anything you need to feel comfortable. This place is both adult and kid friendly. Dr. Yoon and Dr. Ko held a children’s art gallery contest here so their wall has some amazing/​cute art from their patients. The professionalism and service here is really amazing. Every single kid that comes in here comes with a huge smile!
I am here to get a cross bite fixed and I was not pressured into getting any unnecessary procedures such as palate expanders. Instead they suggested I get braces on just a few teeth in the back, and then switch to invisalign. I love how they work with my needs and make it bearable for me so I can continue my day at work without any speech issues. I highly recommend this place!

I normally don’t write reviews, but I’ve been receiving such impeccable service that I felt it was a good time to start.
The offices are clean, hi tech, and filled with friendly staff. I’ve been seeing Dr. Ko for about a month now — he’s knowledgable, professional and very personable! The receptionist, Erin, is just as great! She’s sweet and extremely helpful. If anyone is looking for an amazing orthodontist, Dr. Ko and his staff come highly recommended!

Both of our kids got braces here. Both Dr. Ko and Dr. Yoon are great with kids! The office space is beautiful with plenty of parking. They are friendly and professional. I highly recommend them.

Seriously the best dentists I’ve been ever been to.
The dentist so~~ nice! And very courteous and aware patients need.
