For over four decades, the Cowan Chiropractic Clinic has delivered a sensible, proactive approach to preventative spinal health care and fitness with a program of spinal adjustments, targeted stretching, and core exercise. We also offer massage, orthotics, nutritional supplements and classes in healthy living, such as body detoxification, proper eating habits, weight management, smoking cessation, and stress control. The care you receive here is designed to keep you healthy and prevent chronic conditions from occurring. With chiropractic care and good lifestyle choices, life should be like a candle, burning brightly to the very end, flickering once or twice and then going out. It should not be, as one author said, "Just one damn thing after another." Prevention and good lifestyle choices will decrease the incidence of sickness and disease and dramatically lower the cost of your health care!

Dr. Ken Murkowski IIDr. Ken Murkowski II

Chiropractic Physician

I am a board certified, Michigan licensed Chiropractor that is proud to serve the communities of Grand Rapids, Plainfield, Comstock, and Northview. In addition to the mandatory classes to earn my degree, I also took multiple elective courses and seminars to broaden my knowledge of various chiropractic techniques (sport injury and extremity treatment) and nutrition. I was also a part of a team of 25 doctors that went to Ilheus, Brazil to provide chiropractic care to the underserved people in the community. During the ten-day trip, the team collectively provided care for over 4,000 individuals.
