We are bringing relief from pain to our patients

"After being diagnosed with a herniated disc that had ruptured I went to see Dr. Ammie Chapman for the McGill Assessment. Ammie's assessment gave me the tools and information I needed to be able to care for my infant and carry out daily tasks. She showed me how to protect my spine and gave me exercises to help in my recovery. She instilled confidence and gave me the ability to improve my situation without surgery. For this I will be forever grateful. Thanks Ammie!"
