I developed open venous ulcers on both legs in 1992 and went to different hospitals, clinics and doctors in the DVM area. I first visited Dr. O’Donnell in 2015, and her aggressive and proactive approach to dealing with the ulcers resulted in immediate improvement in my legs. Now, a few months later, I am healed of the ulcer problems that have plagued me for so many years. I would not hesitate to recommend Dr. O’Donnell as a superior vein doctor.
