Dr. Russell is from Chattanooga, Tennessee, and attended medical school in Blacksburg. She decided to go into dermatology because she loves helping people treat skin conditions they don’t think can be improved. “Patients try all sorts of things at home to get rid of what they’re suffering from,” she says. “When they finally come to the dermatologist, they’re met with a variety of treatments they didn’t know were possible.”
