Lucas Tims, ND, FABNO

Overland Park Clinic

Dr. Lucas Tims, ND, FABNO, is medical director of the Riordan Clinic’s location in Overland Park, Kansas. He is a naturopathic doctor who specializes in natural therapies for cancer care, the immune system and more.

Originally from Northwest Arkansas, Dr. Lucas (as he is known to his patients) is a graduate of the University of Arkansas, where he majored in microbiology. He went on to complete his medical training at Southwest College of Naturopathic Medicine in Tempe, Arizona, before moving to Tulsa, Oklahoma, for an oncology-focused residency program at Cancer Treatment Centers of America (CTCA).

In 2013, he passed his specialty boards designating him as a Fellow of the American Board of Naturopathic Oncology (FABNO). He has also earned a Metabolic Approach to Cancer certificate from the Metabolic Terrain Institute of Health (MATC certified).

Throughout Dr. Lucas’ 12 years of practice, he has provided Integrative Medicine support for thousands of cancer patients at multiple CTCA hospitals and clinics. As a board-certified, Naturopathic Oncologist, Dr. Lucas is an expert in how to utilize natural therapies to support patients during any phase of treatment or care setting. In early 2018, Dr. Lucas was appointed to a leadership role serving as Medical Director of Integrative Oncology at CTCA’s Western Regional Medical Center.

Dr. Lucas is also a 2020 recipient of the Excellence in Healthcare for Cancer Care recognition by the Wichita Business Journal.

Dr. Lucas was born into a family where nutrition and organic eating were the norm, and in his formative years he became deeply interested in science and medicine. His upbringing combined with influential mentors during his undergraduate studies helped pave his path toward naturopathic medicine.

In his second year of naturopathic medical school, Dr. Lucas met his future wife. Shortly after they began dating, she was diagnosed with cancer. Helping her through her cancer journey was a turning point for him that fueled his passion for specializing in cancer care.

Throughout his tenure at Riordan Clinic, he has been part of an integrative oncology team offering various naturopathic cancer treatments as well as acupuncture. He works very closely with his patients on diet and lifestyle interventions that promote a healthy immune system and create the right internal climate for the body to heal.

In addition to patient care, Dr. Lucas enjoys doing research, teaching, and writing for medical journals. He is a member, and board member, of the Oncology Association of Naturopathic Physicians and the Society for Integrative Oncology.
