Welcome To The Riordan Clinic!

Riordan Clinic is a world-renowned, academic medical center that has led the world in integrative oncology and complex chronic illness care since 1975.

For more than 47 years people have turned to the Riordan Clinic to restore, improve, and maintain health. We continue to specialize in nutritional testing and holistic/naturopathic treatments for sustained illnesses such as cancer, Lyme disease, gut issues, anxiety and depression, autoimmune disorders, diabetes, and more.

Rather than focusing on a diagnosis and managing symptoms, our goal is to discover the root causes of disease. Simply put, we aren’t just looking to label what is wrong with you – we want to find out why the disease occurred in the first place and then to address those causes.

Our providers combine the best of orthomolecular, functional, naturopathic, and integrative medicine to determine the underlying or root causes of co-learner (patient) symptoms and formulate customized patient care plans to arrest and reverse those conditions.

The Riordan Clinic was established as a 501 (c)(3) non-profit organization with missions in research, provider education, and patient education.
