John Reynolds, D.C.

Doctor of Chiropractic

Dr. Reynolds had long held the belief that maximum health comes from within the body itself. After hearing that chiropractic removes the interference to healing from within, he left his 15 year printing career to become a chiropractor. Working two jobs and attending the College of Lake County, he received his Associate of Science in 1995. Dr. Reynolds moved his young family to Davenport, Iowa, graduating Palmer College of Chiropractic in 2000 and receiving his Bachelors of Science in 2000. Prior to joining Hulsebus-Gehlsen Chiropractic, Dr. Reynolds practiced for 10 years in northeast Illinois practicing full spine with a focus on lower back/disc injury care.

In his off hours, he enjoys trail bicycle riding, outdoor photography, bowling and traveling with his wife to spend time with their two grown daughters.
