TONIIK

Located on Ventura Boulevard in Studio City, TONIIK is a full-service practice that blends functional medicine, regenerative aesthetics and long-term tracking to address aging from the inside out. The practice was founded by MJ Gandon, MSN, FNP, whose clinical background includes critical care and dermatology; Dr. Foster, MD, serves as co-owner, medical director and supervising physician, providing medical oversight for clinical care. TONIIK employs a six-step framework—Biology, Brain, Skin, Regenerative Aesthetics, Body and Optimization—to connect biology with how a person feels, functions and looks, and offers memberships plus nationwide telehealth alongside in-person visits in Studio City and Miami. The clinic positions itself as a precision program focused on measurable, biology-led care and ongoing monitoring rather than single, transactional appointments.
