My goal is to offer the best care possible for every patient, to always explain things in an understandable way, and to give both physical and emotional support throughout their recovery. I was born in Los Angeles, California, and went to college at Stanford University before I began my medical training. My father had always wanted to be a doctor but never could, so I decided to do it. I specialized in vascular surgery because I had two important mentors in medical school who were both vascular surgeons, and I also enjoy the technical challenges of surgery. As a provider, I most enjoy interacting with and helping patients. I previously lived in Chattanooga for 10 years and fell in love with the people and the area surrounding the Appalachian Mountains. Returning to East Tennessee was an excellent professional opportunity to fill a need and serve this community. Outside of the office, you can find me in the mountains hiking, biking, climbing or skiing. Dr. Erdoes can be contacted for an appointment at:.
