High Valley Dermatology & Dermatologic Surgery specializes in the diagnosis and treatment of skin cancer. Dr. Willis and Dr. Sewell are fellowship trained Mohs micrographic surgeons, and thus are fellows of the American College of Mohs Surgery (ACMS), founded by Dr. Fred Mohs. While the detection, treatment, and prevention of skin cancer are a major focus at High Valley Dermatology, we also treat the full spectrum of dermatologic conditions including acne, rashes, warts, moles, etc.
