Dr. Gannon Lee DDS, Mission Viejo CA

I had a fantastic experience at my first visit to Dr. Lee's office. Everyone was extremely nice. I felt that I received excellent care from the front office person, dentist, and the hygienist. I highly recommend Dr. Gannon Lee's dental office. Thank you again for such a wonderful, positive, relaxing experience!

Dr Lee and his staff were very friendly and helpful. He did a great job with my sleep apnea appliance. I am enjoying a better night's sleep already. I would highly recommend him to friends and family.

Dr Lee is very patient and polite with his patients. Takes the time to listen carefully and make sure that they are at ease prior to treatment.

Dr. Lee was professional, answered all my questions, and explained everything in detail. He made me feel confident being in his care!

I see Dr. Gannon Lee for my sleep apnea condition. He specializes in developing mouth pieces which help to minimize sleep apnea and snoring. Since wearing this mouth piece, I am sleeping better and have been able to transition off my CP device. I am very happy with his expertise and his concern for his patience.

Dr. Lee has been diligent and comprehensive while attending to our families dental needs.

He always takes the time to explain the necessary procedures and explain the need for the required remediation.

I had a terrific experience with Dr. Lee. He took the time to explain everything to me. He asked me questions so that he could understand how to help me. I will definitely go back for further treatment!

Very friendly staff! Made the usual scary dentist experience pleasant. Dr. Lee was super thorough in his exam and explanations and a great listener to all my concerns and questions. Expertise and kindness! Special thanks to Maryann, my teeth have never felt cleaner and thanks for all the great flossing and brushing advice. Great experience overall!

Over the past three years, I have suffered from sleep apnea. In spite of trying all kinds of masks, I was constantly at war with them. I felt as if I were suffocating. It wasn't until I discovered Dr. Gannon Lee and Roar Associates that I found help for my sleep apnea. As a result of his close cooperation, and specialization in resolving obstructive airway resistance, I had the appliance properly positioned to provide me with adequate airflow. There has been a significant improvement in my quality of life. I sleep restfully and face each day with renewed energy. My advice is have a sleep study done and then call Dr Gannon Lee, DDS at Roar Associates. The entire staff is super professional, caring and helpful.

I was so happy with my experience with Dr. Lee and his staff when they made an oral appliance for me to wear at night, I made an appointment and went in for routine care. I'm very glad I did.

They took full x-rays, then Dr. Lee reviewed them. Next, he examined my mouth and under my tongue. He found two things that need attention, one of which I knew about already but wasn't a pressing issue. My cleaning was very thorough, which I need every time because of gum and teeth issues.

I greatly appreciate how thorough and professional Dr. Lee and his staff are. Also, they are very nice.

I have been to a lot of Dental Professionals and there’s no comparison with this office. The staff and Doctor Lee, are the best I’ve seen. Everyone is wonderful, compassionate and professional. I believe I have finally found a doctor that can help me!
Thank you Doctor Lee!

The entire staff at Gannon Lee DDS is FANTASTIC! I love the “fun spirit” of everyone at the practice! All members of the staff are incredibly professional, and Dr. Lee spends personal time with all of his patients.

Highly recommend Dr. Lee for anybody looking for a dentist! The staff is professional and very friendly. The practice uses the latest tech for treatment.

Dr. Lee is very thorough, personable and genuinely cares about his patients. Had a temp crown done today and it went great. I have extreme TMJ pain and he was so patient with me when I needed to take breaks. Highly recommend.

Dr. Gannon Lee and his staff are the best! He is a perfectionist and that means everything he does is excellent. I worked in the dental field in the past and I understand what a skilled dentist he is. We have recommended a dozen friends to him. They have all been very impressed with him and his office.
