Philosophy of care | My philosophy centers on you, your personal needs and unique health journey. I believe in a collaborative approach, empowering patients with knowledge and being actively involved in treatment decisions. Whether managing chronic liver disease, guiding someone through a transplant process or offering preventive care, I create a compassionate and supportive environment where you feel heard and cared for. | Why I entered medicine | I chose a medical career to make a positive impact on people’s lives, especially in the realm of complex diseases like liver conditions, where treatment requires a balance of medical expertise and empathy. Liver disease, in particular, often affects individuals and their family in profound ways, and I find it incredibly rewarding to help patients navigate their care, from diagnosis to advanced treatments like a transplant. | Personal interests | I enjoy cooking and traveling, as well as time with family and close friends. I believe in maintaining a healthy lifestyle with proper eating and regular exercise. I'm also committed to finding a balance between work and personal life. Dr. Peyton is rated as a Distinguished provider by MediFind in the treatment of Ascites. His top areas of expertise are Hepatitis C, Primary Biliary Cholangitis, Hepatitis, Endoscopy, and Colonoscopy.
