Dr. Park performed magic when he created a new set of dentures for my 92-year old mother. More impressive than the denture workmanship was the care, compassion, and patience every single staff member showed my mother. If you have ever dealt with a “super senior,” you know how difficult it can be to treat an elderly person. And, this is what makes this team a cut above the rest. From Janelle, to Deejay, to the other dental assistant whose name escapes me, and Dr. Park, this team’s knowledge and professionalism can’t be beat.

Dr Joon and his staff are amazing. They have made a huge impact on my self confidence. I am so grateful that I can now smile and speak without being embarrassed. He hasn’t even finished with my dentures, but the first day he started working on me , he made temporary bottom teeth so I could leave the office with teeth on the bottom and full dentures on top. Thank you so much for your patience with me. Dr Joon and his staff are both companionate, friendly and highly proficient. I recommend this team if you are looking for quality work.

I've been going to Dr. Simon for aprox. three years. I found him by chance and by luck, and I thank the dental gods for leading me here. I have several complex dental issues, in part, due to a traumatic injury, thus requiring extensive implants, crowns, and veneers. Dr. Simon has been a lifesaver! My only wish is to have found him sooner. Finally I am getting the dental care I should have had decades ago. Dr. Simon and his upbeat, cheerful staff, are a godsend. Coming from snooty L.A. , B.H.'s doctors, I can tell you, a great attitude goes a long way with me. It's stressful enough to be in the chair when you have lots of work to be done. But I am always relaxed and calm going into this office. Even when I've needed a re-cementing of a temp. he has come in on several Saturday afternoons to attend to it. SATURDAYS, PPL! Dr. Simon is very sensitive to my needs and his gentle touch is such a welcomed relief. To put it simply, I've had the rest, now I've got the best! Thanks to all in this wonderful office! Dr. Simon, Jean, Janelle, and D.J.! This is the best team I have ever worked with, and yes, I really feel we are a team! Can't thank you enough guys, you keep me lookin' spiffy! And I am thrilled with the results so far. Can't wait for the end results and then, PICTURES! Go no further, if you are looking for a new dentist and one who does restorative work. This is the only place in town or out of town, you need visit. Sincerely, Catte Adams ~ West Hollywood Catte Adams

Dr Simon removed a tooth and put an implant in and it's great. Looks good and works perfectly! He took great care in matching color so that it completely blends in. Dr. Simon also did some bonding for me 18 years ago and it still looks fantastic. He's a wonderful, caring specialist and he has the best, most helpful and friendly staff.

DO NOT GO! Paid $10,000 up front with more money each visit. Bridge/implant failed after 3yrs. Teeth were gray. Awful. Intimidating. Such a rip off. So sad

Hi Bev, thank you so much for your review. I am looking through my patient records and have no records for a patient with your name. Please call my office so I can learn more about your unfortunate experience.

What an amazing doctor! I have been coming to Dr. Simon for over 13 years. Dr. Simon has a huge heart and knows his profession to the “T”. Before anything is done, he explains in great detail the procedure he is going to do. The staff are very friendly and make you feel at home. I highly recommend Dr. Simon to all my friends and family.

My partner has a special dental condition and Dr. Robert Simon and his staff were knowledgeable, courteous, and provide a superb level of care to their patients.

My fiancé was referred to Dr. Simon after another dentist nearly ruined her mouth. Her needs were quite complex, but Dr. Simon did a masterful job in restoring her appearance and function. He was patient and kind and his staff was wonderful. I enthusiastically recommend him to anyone who cares about their teeth.

This place was amazing. I had 2 extractions and it was done so quickly and painless. Dr. Park and his staff were wonderful and very welcoming. The atmosphere was warm and relaxing. I highly recommend.
