Dr. Lee is the Man! Everytime I think the worst, he’s always there with solutions and answers. Truly the top of his game! The staff is super friendly and reliable. I honestly never have to worry about anything.  I am almost finished my Invisalign treatment and could not be happier with the results. Thanks to Dr Lee and the staff at premier orthodontics!

This is my families 3rd set of braces with T.O. Orthodontics, so you know we are sold!. Dr. Lee and his staff are courteous, professional and just really nice people! My older children who have completed their braces have beautiful teeth, realigned bites and have even avoided surgery for impacted teeth (coming in sideways no less!) due to the skill, foresight and patience Dr. Lee consistently practices!

My daughter has a permanent retainer that broke. Her orthodontist retired. We went to see Dr Lee and he was fantastic! He took so much time to fix her retainer and work through an issue that was the result of the broken retainer wire. He is an absolute perfectionist!

I highly recommend Dr.Lee for Invisalign and/or complex cases! Was able to finish my Invisalign in 1.5 year instead of the estimated 2-2.5 years, and I’m really happy with the results and how little time it took. Staff was friendly and Dr. Lee is attentive and very knowledgeable. I’ve heard of cheaper price estimates elsewhere but it was definitely worth a little extra for the quality of work. Office was very nice and clean.

Dr. Lee is great! My daughter started orthodonture with him when she was around seven years old. My dentist recommended him because my daughter had a lot of anxiety at the dentist. Dr. Lee put her at ease and recommended an upper palate expander to correct her crossbite. I was surprised how well she tolerated it, and to my delight it completely changed the shape of her face, making her much more symmetrical. Now, five years later, she is getting ready for braces (Invisalign) and we will be going back to Dr. Lee. I would highly recommend him; great work, great bedside manner, wonderful with children (he has little ones of his own and knows how to talk to them).

I just can’t say how pleased I am with doctor Lee and his office. He was recommended by our dentist . He is a Damon braces specialist and that is why we chose his office. Less appointments, more efficiency and exactness are his specialty. My daughter had a compromise tooth from a previous orthodontist and he ended up not only a saving the tooth but straightening our daughter’s teeth to perfection. The office is only wonderful and I highly recommend. Dr. Lee really cares about his patients.

Frank J. from Winneta, CA (Source: Yelp)


Dr. Lee is quite enthusiastic and patient-focused, you can tell that he is as interested in successful treatment as he is in his patients. Have been seeing Dr. Lee for an Invisalign Lite treatment that is going through a refinement, I couldn’t be happier. Very pleasant environment as well. Very accommodating schedule-wise and I appreciate their SMS reminders.

Anna L. from Calabasas, CA (Source: Yelp)


Was referred to Dr Lee, we couldn’t be more happy with the treatment he’s providing our family. Everyone is truly a super star and beyond helpful. The amazing patient care combined with superb service, make our visits a pleasure. Thank You Dr Lee!

Susan K. from Westlake Village, CA (Source: Yelp)


As patients of the previous orthodontist, Dr. Kobal, we were very grateful when Dr. Lee agreed to see my daughter and fix a broken wire for her.  He was kind, generous with his time, and very helpful.  We will definitely be returning to him in the future.  Thank you Dr. Lee!

Karen H. from Thousand Oaks, CA (Source: Yelp)


My son Nick finished his Ortho 20 years ago with Dr Kobel. Dr Lee took over the practice when Dr Kobel retired.  One of the front teeth detached from the permanent retainer and the tooth moved.  Dr Lee made him a removable retainer to move the tooth back. It worked perfectly and Dr Lee reattached the permanent to the tooth. He is a great Orthodontist and very nice.

I highly recommend Dr. Lee and the Thousand Oaks Orthodontics Team. As an adult straightening my teeth was the last thing I wanted to do, but Dr. Lee took his time to thoroughly explain my options and I am very happy with the results!

Matt R. from Thousand Oaks, CA (Source: Yelp)


My dentist recommended Dr Lee of Premier Orthodontics when I was shopping for an orthodontist. I couldn’t be more pleased with my experience and end result! The SureSmile method of orthodontic treatment is fast and light-years in advancement from old orthodontic methods. I recommend Dr Lee and his staff.

Christine M. from Thousand Oaks, CA (Source: Yelp)


We had only been living in this area for about year when my daughter’s permanent retainer broke.  She had already gone through having braces several years ago with an orthodontist out of state.   I called Premier orthodontics and they were able to get us in quickly.  Everyone in the office was very helpful and professional.  Dr Lee was especially skilled and was able to repair and re-install he retainer.   My daughter says that it fits better than when it was first put in!  Dr Lee treated us with such kindness and professionalism.  We had a great experience!

Dr. Lee and his staff are great. They answer the phone when you call and always try their best to get you an appointment ASAP if there ever is an issue. Dr Lee and his staff have truly made a change in my teeth and I would definitely recommend them. They have made having braces a breeze. Very nice and friendly place.

affordable. I paid by the month. wonderful people. Dr Thomas Lee is the best. Many years ago, I was told by an orthodontist, that in order to straighten my terribly crooked teeth, I would need some extractions. I never went back to him. Dr Lee straighten my teeth without having to pull any teeth!

Judy C. from Oxnard, CA (Source: Yelp)


When both of my kids came to Dr Lee’s a few month’s ago, they had already been in braces for quite some time. Obviously they didn’t have “Sure Smile”, at the “other guys!!!” … My kids have only been here for a short period of time and they are both almost done, with Dr Lee’s know how, and cool technology, how could you be in braces “forever.” You Rock Dr. Lee……..JC

After completing my ortho treatment, Dr. Lee started my sons treatment, which is quite complex. Dr. Lee consulted with the oral surgeon as well as pediatric dentist to formulate a customized treatment plan, tackling several aspects of treatment in parallel to keep the duration of treatment on track. Dr Lee started treatment last week and today, SUNDAY, my son was uncomfortable and a bit swollen due to a metal device placed in his mouth. I texted Dr Lee at 7:30am today (again, SUNDAY), and by 9am, my son was in Dr Lee’s office, being taken care of. Dr Lee is without a doubt, above and beyond, in terms of his expertise, patient care and extending himself to get the optimal treatment outcome. After completing my own treatment with him and now my son, I’d highly recommend him.

Sandy R. from Granada Hills, CA (Source: Yelp)


I’ve been taking my son to Dr. Lee for 2 years now and can’t give enough praise! Dr. Lee and the whole staff have always been friendly and helpful. We have a hectic schedule and they always tried to work with us without making me feel bad. My son’s issues were corrected much quicker than I thought, and before we knew it the braces were off. Since then, my son has frequently commented on how he misses his ortho visits. Thank you all so much for the excellent treatment!!

James S. from Ventura, CA (Source: Yelp)


Dr. Lee is fantastic.  We have had the best experience with he and his staff.  I would highly recommend the free consultation and see it for yourself.  You get the best care and the staff is so nice.  Love the office.  I get to relax with a cup of coffee while my son is been treated.  His teeth are almost to perfect.  It has truly been a great experience.

Dr. Lee and his staff are great. Friendly and professional. After both my son and one of my daughters went through this with Dr.Lee, he asked me why I waited my whole life to straighten my teeth. They made it so painless and it’s going so well I don’t know why I put it off for so long. This time next year I’ll be finished. Should have done this a long time ago

The best orthopedic office in the county. I guarantee you will have a pleasant experience! The doctor is super friendly and never made me feel pressured to get treatment there. Every office I’d gone to would try to shove invisalign down my throat and tell me it was best (I’m not knocking it, it just wasn’t realistic for me because I can’t be trusted to keep something in place for 20 hours. I knew I’d take it out and “forget to put it back in”.) this office gave me options and pricing and let me decide without making me feel like they were just sales people. The gentleman that coordinates the treatment, Gabriel is amazing! He always has a welcoming smile no matter what time I go in. He was patient will all of my questions which I’m sure he has answered over and over again! The waiting room alone is so clean and smells nice, it’s organized and I never have to wait very long to be seen as long as long as I am there on time heehee. Overall, treatment isn’t cheap, but you get what you pay for!

Many orthodontists told me they couldn’t fix my slight misaligned jaw and tiny underbite without having surgery. I kept searching online for doctors around california even arizona. After searching i came across dr. Lee . I did some research and decided to get a consultation with him. He made me so happy when he said he could fix my problem with no surgery. Even though i had to drive kind of far i didnt care. And i dont regret it because he didnt finish my treatment until made sure we were both satisfied with the results. Guys i highly recommend him. Great dentist that is honest, nice and caring. And his staff is great!!

Amna H. from Los Angeles, CA (Source: Yelp)


Dr. Lee goes above and beyond in his treatment planning, execution and patient care.  Dr Lee had already done a fantastic  job on my braces, and he just started treatment on my son who has a pretty complicated case.  Dr. Lee is working with an oral surgeon and pediatric dentist to ensure an optimal treatment plan for my son.  My son started treatment last week but was in pain this weekend.  I texted Dr Lee on a Sunday morning and he had us come into the office the same morning, spent an hour making adjustments to the device and sent my son home very happy and relieved.  Without a doubt, an above and beyond experience!

Heiko H. from Simi Valley, CA (Source: Yelp)


Dr. Lee is a great orthodontist. He is caring, knowledgeable, and up-to-date with technology. Compared to other orthodontists in this area, his office provides a better quality service and has a better price. Thank you Dr. Lee for your service!

Pete P. from Los Angeles, CA (Source: Yelp)


Just finished my Invisalign treatment after a hard years work!  Dr. Lee and staff are incredibly friendly and professional.  They do not miss a beat when it comes to customer service and satisfaction.  This is one of the best medical practices I have experienced!  Highly recommended!

Alexa B. from Los Angeles, CA (Source: Yelp)


Dr. Thomas Lee is the best! I was going to another orthodontist before I found Dr. Lee and I was spending a lot of money and not seeing any results. I knew within five minutes of meeting Dr. Lee I had to switch to him! I just finished Invisalign treatment with him and couldn’t be happier. He is an absolute perfectionist and is so professional and knowledgeable. His office is very clean, courteous and organized as well. I referred several of my family members to him and they all love him too. If you need orthodontic treatment I highly recommend him.

Dr. Lee and his team are AMAZING! I love his access and availability. They are so accommodating for me. His practice has that CLEAN, great energy feel. You know you are in the right place. If you are looking for that healthy smile and wanting to improve your function this is the place to go. The consultation is free and why not go see what is possible.

Dr. Lee and the staff at Premier work hard to make their patients happy and comfortable. From the iPads and kids movies playing on multiple screens to the hot chocolate and cappuccino machine and monthly contests and giveaways, Premier Orthodontics has their patients’ comfort in mind. My daughter says that “the orthodontist is my Happy Place.”

P. from La Puente, CA (Source: Yelp)


I went to Orthodonist Dr. Thomas Lee after a friend had referred me, and she was right, he’s been great. He is amazingly calm and patient with me and puts me at ease. I got my chipped tooth fixed and invisalign. His staff is great at reminding me to show up. They are very professional and I feel welcome with every visit. He’s also really funny and tells me stories about his kids every time I go. They’re soooo cute, ask to see pictures of his kids when you go.

Where do I start…I’ve been with Dr. Lee for 6 years…my third child is now doing treatment with him and he’s the best! Dr. Lee is always friendly, available, and knows what he’s doing. Dr. Lee and his staff are above and beyond amazing and I highly recommend them!!! My kids love going to the office and I can’t imagine going anywhere else. 10 STARS!!!


Dr. Lee is a trusted orthodontist in Thousand Oaks providing a full range of orthodontic care including Braces for children and adults, comprehensive treatments including early orthodontic treatment for children, and branded orthodontic treatments including Invisalign, Invisalign for Children and Teens, and Damon Braces. After completing my orthodontic residency in May 2002, I moved to Ventura County and became an associate in an orthodontic office in Oxnard. I purchased that office later that year in December. I also began practicing in the Conejo Valley in Thousand Oaks starting in 2009. Since then, I have been serving the communities with the goal of providing friendly, caring, high-quality orthodontic treatment that utilizes the most up-to-date techniques and technologies. Invisalign®, Damon System, 3D cone bean computed tomography (CBCT), and temporary anchorage devices (TAD) are amazing technological advances that I have implemented into patient treatment. I grew up here in Southern California, in the San Fernando Valley, and attended the California State University, Northridge for my undergraduate education. The University of Southern California School of Dentistry was my next stop for the next seven years: four years to earn a Doctorate of Dental Surgery, and three more years of orthodontic residency and a Master of Science in craniofacial biology. Being a positive, contributing member of our community and society is important to me. Children are our future. That is why I have chosen to support the Boys and Girls Club. This wonderful organization gives a safe, positive, nurturing, supportive place for kids and teens to play and learn. My wife Heidi and I met during our undergraduate studies in 1993. She is the pillar of my life. We have two wonderful children, Parker and Sophie. When I am not in the office, my time is spent with my wife and kids, mountain biking, watching USC football (FIGHT ON!), and snow skiing.
