After 22 Dr's from all over VA & George Washington hospital, Dr. Grant Anhalt was the only Dr. That actually did a biopsy of each leg, found out what I had (Vasculitis), leg ulcers on both legs & knew exactly how to treat it! It's not curable but I'm in remission. Dr. Anhalt is a very caring person that has excellent bedside manners.Debra Ridgeway
