Chiropractor Mark McCullough D.C., Director

Chiropractor Battle Creek MI Mark McCulloughDr. Mark McCullough graduated in 1991 with a Bachelor of Science in Chemistry degree from Michigan State University. From there he worked as an analytical, pharmaceutical chemist and spent many years performing research and development in the pharmaceutical industry. Later, Dr. Mark sought to expand his knowledge of how the body functions in healing and wellness and the best applications for reaching optimal health as opposed to managing disease. To this end, he graduated from Palmer College of Chiropractic in 1999 as a Doctor of Chiropractic.

Dr. Mark is a contributing author to a New York Times best-selling book called One Minute Wellness, as well as the Best-Sellers The Definitive Guide to Youth Athletic Strength, Conditioning and Performance, and The Success Secret (co-authored with Jack Canfield). He’s the author of The G-Zone: Glucose and has been featured on ABC, CBS, NBC and Fox News affiliates across the country. Dr. McCullough is the team doctor for the champion Battle Creek Knights basketball team. An athlete himself, Dr. Mark competes in numerous sporting events, including marathons and triathlons. Dr. McCullough has hosted the weekly radio show “For Your Health” on WBCK for four years. Dr. McCullough speaks at local corporations, community events, schools, and churches.

Dr. McCullough’s mission is the dedication to reach people of all ages and help them begin a substantial, life transformation. The goal is to start the body healing, resulting in feeling and functioning better than it ever has before. This passionate work began when his son was first diagnosed with autism. Through a customized, nutrition plan, a life-management plan, and dedication, his son is now a mainstream teenager excelling in academics, music, and sports.

Dr. Mark is happily married to his wife, Missy, for over 24 years. Missy graduated in 1991 with a BA in Communications from Taylor University. She is passionate about true health and educating her clients as well as her community about how they can achieve their best when it comes to living a healthy life. Together they have two beautiful children that they love to spend time with; but who now live in Australia attending the Hillsong International School of Leadership. Dr. Mark and his wife’s vision is to see their city become a place of destination in the way of health like it once was many years ago.
