Here, at Amesbury Chiropractic & Sports Injury, we emphasize the value in providing patient-centered care, and understanding that every patient and family are unique in their own situations. Chiropractic is a system of complementary medicine based on the diagnosis and manipulative treatment of misalignments of the joints, especially those of the spinal column, which are held to cause other disorders by affecting the nerves, muscles, and organs. Dr. Peter Antonsen is a certified chiropractic sports physician, as well as a certified chiropractic extremity practitioner.
