Dr. D. Ryan Skinner is the founder of Skinner Dermatology & Mohs Surgery and one of the most experienced Mohs micrographic surgeons in East Tennessee. With nearly 20,000 Mohs surgery cases to his name — nearly all performed right here in Blount County — Dr. Skinner brings a rare level of subspecialty expertise to the community he calls home.

Dr. Skinner is dual board certified in dermatology and Mohs micrographic surgery, and he completed a fellowship in cutaneous oncology and reconstructive surgery. This combination of training means that when skin cancer is diagnosed, he is fully equipped to not only remove it with the highest precision, but to restore what was taken — whether through skin grafts, adjacent tissue transfers, or complex interpolation flaps.

Before founding Skinner Dermatology, Dr. Skinner spent nearly a decade serving the Blount County community through Blount Memorial Hospital, building a reputation for outstanding surgical outcomes and genuine, personable care. He has volunteered at free clinics, participated in medical mission trips to the Dominican Republic, and organized skin cancer awareness events throughout the region.

Dr. Skinner has been published in peer-reviewed journals including the Journal of the American Osteopathic College of Dermatology and Pigment Cell & Melanoma, and has presented at international conferences including the Australian College of Cutaneous Oncology in Melbourne, Australia.

Dr. Trent Gay is a board-certified dermatologist and Fellow of the American Osteopathic College of Dermatology who has been serving patients in Blount County since 2018. He practices the full breadth of medical, surgical, and cosmetic dermatology in a busy outpatient setting, managing everything from acne and eczema to skin cancer and complex surgical cases.

Dr. Gay completed his medical training entirely within the Appalachian region, earning his Doctor of Osteopathic Medicine from Edward Via Virginia College of Osteopathic Medicine in Blacksburg, Virginia — graduating with honors — before completing his dermatology residency at LewisGale Hospital Montgomery, where he served as Chief Resident in his final year.

He has participated in medical mission work in the Dominican Republic, Honduras, and Appalachian communities, and volunteers in free skin cancer screening through the American Academy of Dermatology's Spot Me program. Patients throughout the region appreciate his thorough, personable approach and his commitment to delivering the highest standard of care close to home.

Alexis grew up in East Tennessee and completed her undergraduate studies at Maryville College, earning a degree in Biochemistry before going on to Lincoln Memorial University to complete her Master of Medical Science in Physician Assistant Studies.

She brings a meticulous eye, a calm bedside manner, and an ability to connect with patients across all ages and backgrounds.
