"Thank you for doing what my oncologist could not" - George

“Had a case of prostate cancer in 2018. Your services and vitamin C brought my PSA down to ,0.01 (nondetectable) in less than 4 months. Would recommend vitamin C be used! Thank you so much for doing what my oncologist could not.”

Welcome To The Riordan Clinic!

We seek to identify the underlying causes of illness and correct them using a variety of natural, non-toxic modalities.

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.

The Riordan Clinic is a not-for-profit 501(c)(3), nutrition-based health facility with three locations in Kansas: Wichita, Hays, and Overland Park.
