Your prices are way to high. I'm looking for a new dentist that is closer and more in my budget range.

$330 for cleaning and X-rays is double what I've found in my area.

The quality and care you receive at this office is never a surprise. I have been a patient of Dr. Lee's office for many years and I was treated at all visits by both the doctor and his staff with utmost professional and friendly care.

Dr. Lee and his staff are the BEST. Dr. Lee is very thorough and explains what he is doing every step of the way. He refers to his patients as "boss" and that is an accurate description of how he treats the patients, if anything is uncomfortable, just give a nod or a wince and he stops and finds an alternate way, more comfortable way of doing what needs to be done. Once he is done with his examination of my mouth, he tells me exactly what to do to improve and acknowledges my own good home dental care. He and Kristen give personal treatment, they remember what was happening in your life at the time of the last visit and ask for updates during current visit as well as share some of what is happening in their lives. It is like having a conversation with friends, save for the dental chair.

Most caring, knowledgeable, and patient dentist ever =) He is somewhat a perfectionist!

Always a pleasant visit, even if some rough procedures.

Going to Dr, Lee, no matter the situation, is always good because of him and his gentleness.

5 stars Customer since 2017

Dr. Lee is a very attentive, caring dentist and takes the time to explain your treatment so that you know what is

being done and the options you have. I intend to recommend him to all my friends..

I have been going to Dr. Lee for longer than I can remember. I now live in West Los Angeles and journey out to Diamond Bar because of the outstanding service I receive from Dr. Lee and his staff.
