About

At Functional Health Center of the Carolinas, Dr. Corey Riser built a clinic where functional and direct primary care work side by side. He founded the Fort Mill, SC practice in 2017. In 2025, the clinic expanded to a second location in Mt. Pleasant, SC.

Dr. Riser brings over 300 hours of post-doctoral education in functional medicine to his clinical work. The practice treats patients from a comprehensive, integrative standpoint. The team focuses on root causes rather than symptom management alone. Clinical focus areas include Type II Diabetes, hypothyroidism, autoimmune disease, gastrointestinal issues, hormone imbalances, and cognitive decline. The practice also offers chiropractic care, medical aesthetics, peptide therapy, bio-identical hormone replacement therapy, GLP-1 weight loss programs, and pregnancy support. Dr. Justin Garzone serves as Medical Director, bringing board-certified internal medicine expertise to the team. Members receive all lab work, sick and wellness visits, and telehealth access under one flat monthly fee. Lab testing happens at home or at any Labcorp location, with an extensive diagnostic menu covering organic acids, SIBO breath testing, heavy metals, mold and mycotoxins, and genetic analysis.
