Obsidian Men’s Health is a new kind of practice — one dedicated solely to men’s sexual health, in an environment designed with luxury, privacy and unfettered physician access in mind. Shane Geib, M.D. and Marc Richman, M.D. have more than 30 years of combined experience helping men and their partners achieve and maintain a healthy sex life. They founded Obsidian in Tysons Corner, Virginia, to provide men with a place to attain sexual and overall wellness in a relaxed, secure setting.
