Root Cause Testing was founded on the belief that lasting health requires more than treating surface-level symptoms. Riannan Osborne brings a functional medicine lens to virtual care, helping patients across the country access the kind of thorough, root-cause investigation that traditional healthcare often overlooks.

Our nationwide telehealth model means you don't have to travel to get expert functional medicine support. We use advanced lab testing and detailed health assessments to create personalized care plans that address your unique biochemistry and health history. Every patient receives individualized attention and a clear path forward.
