Dr. Diana Ruth D Parnell, MD

I requested treatment for a few light brown age spots I had on my face. Dr. Diana Parnell used liquid nitrogen to apparently freeze them off. In the past other dermatologist had effectively used laser treatment though, with all the sun exposure spots reappeared in other locations on my face. Her aim was completely off the liquid nitrogen left bright red spots, then scarring. The brown spots were never touched, as she burned completely healthy area's of my skin. It seemed like she did this on purpose, I found her pretentious and unprofessional. Avoid this practice at all cost.

The best dermatologist in Northern California. When I mention her name to other doctors they all say the same thing "Oh she is the best - the gold standard"

Dr Parnell is absolutely first rate. I would recommend her without reservation.
