The Riordan Clinic (originally named Olive W. Garvey Center for the Improvement of Human Functioning, Inc.) was founded in 1975 by Dr. Hugh Riordan and Olive W. Garvey on the premise that all complex chronic illnesses, including cancer, were caused by nutrient deficiencies. They believed that correcting these nutrient deficiencies or imbalances would create an environment of healing and lead to an arrest or reversal of disease conditions. 

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

Riordan Clinic providers combine the best of orthomolecular, functional, naturopathic, and integrative medicine to determine the underlying or root causes of co-learner symptoms and formulate customized patient care plans to arrest and reverse those conditions. Specialties include: integrative oncology, integrative autoimmune disorders, integrative infectious diseases, anti-aging and longevity, functional psychiatry, and restorative and regenerative medicine.

Many patients use the Riordan Clinic exclusively to address their health issues, others choose to integrate our therapies with those of their traditional doctor. We provide the ultimate form of healing – hope. Whether you are at the beginning of your path to wellness or you have been challenged for many years, we can help. Take charge of your health by becoming a patient at the Riordan Clinic today.
