Yes, an RN can own a medical spa in most states—but with significant structural and operational constraints that vary by jurisdiction and directly affect profitability and liability exposure.
The core issue is the Corporate Practice of Medicine (CPOM) doctrine. In roughly 20 states, CPOM prohibits non-physicians from owning a medical practice or controlling clinical decisions. In those states (including California, Texas, Florida, and New York), an RN cannot be the sole owner of a medical spa that performs physician-delegated procedures like injectables, laser, or microneedling. The practice must be owned by an MD or DO, or structured as a professional corporation where a physician retains clinical control.
