Our Services

Dr. Ammie Chapman is more than just a chiropractor. As a McGill Method Certified Practitioner, Dr. Chapman takes a holistic approach to patient care. At AM Chiro Performance, you will receive a customized treatment plan to address your specific health and wellness needs. How you use your body outside of the AM Chiro Performance clinic affects treatment outcomes. That is why, in addition to caring for your spinal health, Dr. Chapman provides diet, exercise, and lifestyle modification recommendations for optimal health. At your initial visit, you will discuss your exercise regime, analyze your movements, and review your work ergonomics. These are all important aspects that affect your healing and help prevent future injuries.

Traditional medicine is often quick to jump to surgery as a solution for nerve pain. However, in many cases nerve pain can be relieved by a practitioner skilled in neurodynamic assessment and treatment. Dr. Chapman offers a less invasive approach to treating pain.


Dr. Chapman believes that chiropractic care should include more than simply a "crack" of your back or neck. She provides her patients with half-hour appointments, and takes the time to understand the underlying cause of their pain. In addition to spinal manipulation, Dr. Chapman offers a variety of treatment options to meet the needs of her patients.
