Edward B. Portnoy, MD

My Philosophy and Approach to Wellness...

My philosophy of medical practice can be described as "proactive wellness' This is accomplished by developing close and personal relationships with my patients through frequent interactions. My staff and I also make extensive use of the latest tools and technology for early detection and disease prevention. We strive for improved quality of life as well as longevity for all of our patients.
