Wonderful practice! Came in because I had a weird spot on my foot and instead of "watching it" like other doctors do it was removed and sent for biopsy right away! Everyone was so kind and it was an amazing experience!

Had four skin issues resolved very quickly. Will always go to Dr. Geller for derma issues. He identified a rash I had over the other dermatologist in town. As far as I'm concerned he's the guy to see.

Front desk is useless. Hung up on my health insurance provider twice when they tried to call for a service code to see if they cover it and then told them they dont actuallyknow the code when they called for a third time. Basically told me to schedule an appointment without knowing if it's covered and they can check at that time. are you kidding me?

Office operates like a well-oiled machine. Entire staff is polite and professional. You go in, they do what they need to do and you are out. No fuss, no muss.

Dr. Geller's approach with detecting skin cancers early is appreciated as I have had numerous biopsies return positive for precancerous, BCC, and Squamous. (I would rather lean toward aggressive sampling and catch early cancers, rather then be conservative and miss them.) He and Cindy have treated these well without issue. Appointments are most always close to on time.

In very rare cases when they run late, they acknowledge and apologize, which is important to me (I understand they may run into issues w patients that require more time). They and their staff are all very kind and friendly. I recommend.

I was there for a follow up on a dry patch to my elbow. I was treated to a chemical peel which made my skin so soft.
