Lee Joon Y DDS

Best staff in front, dental assistants and Dentist in the area! I love them! They’re honest, fair and very accommodating! The longest I’ve ever waited was 10 mins! Dr. Lee is gentle, experienced, empathetic and always, always professional. I leave there feeling well-takes care of and would recommend him to all my friends and family. Thank you, Dr. Lees!!! You are my only go-to dentists!!

Dr Lee was very professional and as usual very informative as to what procedure(s) I may need. His staff is very pleasant and welcoming. Visiting the dentist isn’t usually an experience anyone can get excited about, but, Dr Lee and his staff are friendly enough to create an environment where excitement is key so patients feel comfortable when greeted with happy smiles.

I have been seen doctor Lee over the past 5 years. He is an outstanding dentist, very patient, and explains all procedures. His current staff is also outstanding and very helpful. Moreover, it's very easy to make an appointment that matches my schedule. Thank you Dr. Lee.

I’ve only been here a few times so far, but am very happy here. They take Medi-Cal too, which is awesome. Everyone who works here is very friendly and kind, not at all rude. Their relatability makes me feel very comfortable as a patient and I don’t feel judged when I don’t have perfect dental health. Seriously, all my previous dentists have given me such a hard time whenever I’ve needed dental work done. I take great care of my teeth, but just genetically predisposed to poor oral health. I feel very comfortable coming here and never feel anxious or uncomfortable in any way. Highly recommend them because of their interpersonal skills. On another note, it’s great that Dr. Lee comes from a family of dentists. You know he is experienced and trustworthy. The only down side I can think of is that twice so far I’ve shown up on time for my scheduled appointment and have had to wait since some of the dental assistants were on lunch. But that doesn’t bother me because I’ve had worse wait times at other dentist offices.

Dr. Lee has been my go to dentist for last ten years. His expertise in doing dental work excels in north Orange county. About two years back, I started a new job in very south corner of Orange county but I still goes to his office for all my dental operations since he is trustworthy and does excellent work. He also takes emergency appointments for his patients. Please go and see him. You would be saying same thing after the visit.

Dr. Lee is the best dentist on this planet. He uses anesthetics and you are always comfortable even when the procedure is very involved. He is very friendly, cheerful and empathetic. He gives better than what your money can buy. Thanks Dr. Lee for fixing my two broken veniers, two broken crown, extracting my bad tooth, giving me a tooth implant, and really thorough cleanings.

I've been going to Dr. Lee for over 15 years and I've never needed to know any other one I found him. like most people, I had bad experiences with dentists growing up and that alone made me want to put off going until the last resort. we had just moved to Diamond Bar and I had an extreme toothache on a Saturday in a new town, luckily I was going to the bank in the same parking lot and saw they were open. The first thing they did was elevate the pain, then took the time to explain all my options but making it easy to understand and with an eye for the future in mind. I've since then been seen by everyone in the family and they're all great! They've taken every insurance I've had over the years and worked with me when I've had none also. Very clean, friendly, knowledgeable and as pain free as possible. I cannot say enough about the Lee Family, as they have saved me and my smile and of course everyone I know now goes there and loves them just as much.
