George Lynch, MD
Biography:
I am proud to practice Bariatric and General Surgery with The Surgical Clinic. I grew up in Pulaski TN, received my secondary education at Giles County High and Montgomery Bell Academy, majored in English at Dartmouth College, and taught high school in rural Kenya between college and med school. I spent 9 years at Vanderbilt for med school and residency. My wife Amy and I lived and worked in Greenville SC from 1997-2002 before returning to Nashville. We have two sons. Henry works for a software company and Haynes is an aspiring chef. When I’m not at work, I enjoy cooking, gardening, hiking, sailing, golfing, and solving the NYT spelling bee.
Care Philosophy:
It is a great privilege to work as a surgeon. I’ve always been impressed that patients who hardly know me entrust their care to me with little fanfare. That trust comes with a huge responsibility, and I take that seriously. For me, that means working hard, listening to, and being honest with my patients. It means that my own education didn’t stop when I finished my formal training. I believe patients should be active participants in their own health outcomes. That might mean smoking cessation or weight loss or starting an exercise routine. Some patients appreciate this message, others not so much. I am conservative in my decision making. Surgery can be an awesome tool to help improve quality of life. But operations have risks, and there need not be an operative intervention for every malady. I try to educate my patients so that we can make informed decisions together.
