General Surgeon Dennis Lewis Joins Ivinson’s Surgical Team

Dennis Lewis, MD joins the surgical team at Ivinson Memorial Hospital where he will provide general surgery call coverage and practice in a part-time basis in the Surgical Clinic at Ivinson Medical Group.


Dr. Lewis comes to the Ivinson team from SageWest Health Care, where he performed surgeries in both Riverton and Lander. Of his more than 33 years of practicing as a general surgeon, Dr. Lewis has spent 13 of those years practicing in Wyoming.


Dr. Lewis completed his Bariatric Fellowship in New York City at Mount Sinai Hospital and finished his surgical residency at Greenville Hospital in South Carolina. He earned his medical degree from the University of Florida. At Ivinson, Dr. Lewis will be providing a variety of general surgical services including hernia repairs, colonoscopies, endoscopies and other reflux and bowel related surgeries.


“Deciding to have surgery can be a scary decision,” Dr. Lewis said. “I like to sit down with my patients and explain their procedure in layman’s terms. I draw a picture of what the problem is and how we are going to fix it. I explain the options and let the patient tell me how I can help.”


Outside of his regular practice, Dr. Lewis has worked extensively with the humanitarian group Doctors Without Borders. His volunteerism allowed him to use his medical expertise to provide care in the Dominican Republic, Nigeria, Zambia, Afghanistan and South Sudan.


In his free time, Dr. Lewis enjoys caring for his several animals at his small ranch outside of town and preparing for his next cycling race. He is looking forward to living and working in Laramie, allowing him to spend more time with his wife, children and several grandchildren.


Dr. Lewis will begin seeing patients at Ivinson this January. To schedule an appointment with Dr. Lewis or any other member of our surgical clinic team, call or text 307-755-4540. Learn more about Dr. Lewis on our website: ivinsonhospital.org
