Portico Longevity
21 George St Ste 100, Charleston, SC
Portico Longevity is a physician-led longevity, primary-care and medical-spa practice on George Street in downtown Charleston, a short walk from Marion Square and the College of Charleston. Among the IV drips, hormone and peptide work and Valmont facials is a simple contrast setup: a private room with an infrared sauna pre-heated to about 140°F and a pre-cooled ice bath around 39°F, with towels and slippers laid out for you. The Cold Plunge & Infrared Sauna Experience is a 30-minute private booking, made through Portico's online booking or on ClassPass, so you never share the heat or the cold with strangers. It is a gentle introduction for anyone curious about contrast therapy, and an easy add-on to a facial, massage or IV appointment. Portico does not publish a price for the experience; call the front desk or check the booking page. Clinic members on the Primary Care or Gold plans get 10-20% off spa services. Founder Dr. Sarah Relyea-Logan has practiced family medicine for nearly 30 years and built Portico as a direct-pay alternative to insurance-driven care, so the sauna and plunge sit inside a broader plan built around sleep, stress, nutrition and recovery. The practice moved here from its original home on Burns Lane.
