About Us

Dr. Jake was born and raised just outside of Rolfe, Iowa. Growing up, he was very active in athletics and fell victim to many injuries. It was chiropractic that kept him from spending more time on the sidelines. After his 8th grade football season, he knew he wanted to be a chiropractor.

His education started at the University of Northern Iowa, where he received a major in Biology and a minor in Chemistry. He then received his doctorate from Palmer College of Chiropractic in Davenport, Iowa.

Dr. Jake married Victoria in 2015. She is now a dentist at Pocahontas Dental Associates in Pocahontas. Dr. Jake and Victoria stay busy with their two sons.

Dr. Jake is continuing his passion for farming and chiropractic. He lives on an acreage just half a mile from the family farm. He refuses to let his dream of both farming and being a chiropractor fade.
