Dr. Cathryn Harbor (right) meets with patient Robyn Zamorski during an appointment at Harbor’s Lexington practice. Zamorski, a Salem resident, drives to Lexington for treatment of Lyme disease because she said she cannot get adequate treatment closer to home. After a couple of months’ treatment with Harbor, Zamorski said she has experienced a noticeable improvement in her symptoms. Some doctors have been sanctioned for treating patients with therapies that go beyond established guidelines. KYLE GREEN | The Roanoke Times
