Wasted my time.
According to this listing and the listing with my insurance, Dr. Clark is a dermatologist. When I called the office, listed as "Cary Skin Center", I am immediately asked if this is for skin cancer. No, I replied, I have not been diagnosed with skin cancer, and then I am refused an appointment because "that's all we do is skin cancer surgery." Perhaps that should be on their website and other listings, and perhaps they should call themselves "Cary Skin CANCER Center". Thanks for wasting a great deal of my time researching a dematologist.
