"First time patient. I heard about Optima Dermatology on an advertisement on iheartradio. Made an appointment and was seen by Dr. Delost, and this doctor was beyond terrific. He made me very comfortable with something that I've been living with for a while. Dr. Delost was competent, compassionate, and very reassuring. It is because of Dr. Delost that I would recommend Optima Dermatology. I cannot thank him enough. He's an asset to the medical profession."
