Mark J. Hoy, M.D., is originally from Philadelphia, Pennsylvania. He attended Boston College and graduated cum laude with a bachelor’s degree in biology in 1983. He returned home and attended Temple University School of Medicine, graduating with honors in 1987. He completed a general surgery internship and otolaryngology residency at the University of Louisville, serving as chief resident in 1992.

After moving to Mount Pleasant in July 1992, Dr. Hoy quickly established one of the premiere private practices in the area. His success caught the attention of Dr. Paul Lambert, chairman of the Otolaryngology Department at MUSC. Together, they forged a relationship that eventually brought Dr. Hoy onto the full-time staff at MUSC as Assistant Professor beginning in 2001.

Dr. Hoy now serves as director of the General Otolaryngology Division. He divides his time between all MUSC hospital locations, the Ralph H. Johnson VA Medical Center and sees outpatients at clinics in Rutledge Tower and MUSC Health East Cooper in Mt. Pleasant. His surgeries are performed at the Rutledge Tower ambulatory surgery center and the main operating room at MUSC Health.

Dr. Hoy has been board certified by the American Board of Otolaryngology since 1992. His career interests include: sinus disease; sinus surgery (including image-guided surgery); the diagnosis and treatment of allergy; and, general pediatric otolaryngology (tubes, tonsils, adenoids, hearing loss, etc.). He is an active member of the American Academy of Otolaryngology, Head and Neck Surgery, the American Academy of Otolaryngic Allergy, and the American Rhinologic Society. He has served as a member of the MUSC credentialing committee for six years (as of 2018).
