We are proud of our history at Damrow Chiropractic Office. We were founded in 1914 by EH Damrow DC, Dr. Damrow’s grandfather. Chiropractic was just in its 20th year of existence when EH opened his office in downtown Janesville. He was joined in 1950 by his son, Dr. Jack Damrow (pictured on the right), who practiced for the next 45 years while raising his family of 9 children. A community leader and wonderful provider, his presence continues to be felt every day at Damrow Chiropractic.
