After serving as a missionary for his church in Argentina, he returned to Wisconsin to complete four years of college and graduated summa cum laude from the University of Wisconsin in Eau Claire. He went on to medical school in New York City at the prestigious Columbia University College of Physicians and Surgeons, from which he graduated in 1987. He then served four years in the US Navy as a general medical officer, followed by a three year residency in Dermatology, and a one year Fellowship in Mohs Micrographic Surgery, both at Geisinger Medical Center in Danville, Pennsylvania. Although the diagnosis and treatment of skin cancer continues to be his primary interest, he also keeps his skills current in general dermatology. Of the five practicing fellowship-trained Mohs surgeons in Idaho, Dr. Willis has the distinction of being the longest practicing in the state.
Since establishing his practice in Idaho Falls many years ago, Dr. Willis has built a reputation for skilled and caring treatment of his patients at High Valley Dermatology.

Dr. Sewell is a familiar face to many in Idaho Falls having spent his junior and senior high school years here.

Leaving Utah and Idaho behind, he attended medical school in our nation’s capital at The George Washington University School of Medicine in Washington, D.C. Following graduation in 2003, he stayed at GWU for a one-year internship in internal medicine and then moved on to dermatology residency at Geisinger Medical Center in central Pennsylvania. Upon the conclusion of residency training and obtaining a board certification in 2007, he stayed at Geisinger for another year. He combined a fellowship in Mohs Micrographic Surgery and Procedural Dermatology. While there, he was also on the general dermatology staff at Geisinger, both seeing patients independently and supervising an evening resident clinic.
In 2008, Dr. Sewell moved to Idaho Falls to begin private practice by joining long-time friend and colleague, Dr. James Willis at High Valley Dermatology. Dr. Sewell has always been concerned about going the extra mile to ensure patients are well cared for and pleased with their experience as his patient.
