The doctors and staff of The Chiropractic Health Center

Dr. Mary Hasley, Dr. Adam Jameson, Dr. Zachary Jameson, and Dr. Olivia Elias have years of clinical and practical experience. Our chiropractic family tradition started over two decades ago and now includes two generations of natural healers.

Our family has been freeing people from pain since 1997 in our clinic in Lee's Summit, Missouri. As Chiropractors with experience, we are committed to promoting the health and well being of each patient.

We use a "whole person approach" when taking care of patients. By combining the very best hands-on-technique, state of the art physiotherapy procedures, and providing the newest and best natural vitamins and mineral supplements on the market today, our Lee's Summit chiropractors are able to help you to accelerate and/or maintain your journey to excellent health.

My Name is Dr. Zachary Jameson, I am passionate about chiropractic because I believe the body has a powerful ability to heal itself when the spine is aligned and we pursue healthy lifestyle choices.
