For more than 45 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 doctors combine in-depth nutritional lab testing, a comprehensive medical evaluation, and the utilization of a variety of holistic, non-toxic treatments and services to provide a customized, holistic treatment plan.

Our nutrient store specialists are available to answer questions and process orders Monday through Thursday from 8:00 am - 5:00 pm and Fridays 9:00 am - 4:00 pm. Thank you for visiting the Riordan Clinic Nutrient Store, we look forward to serving you!
