Dr. Jeremy Ruesch grew up in Wisconsin Rapids, Wisconsin. After graduating from the University of Wisconsin-Eau Claire with a Bachelor of Science in Biology, he attended Palmer College of Chiropractic in Davenport, Iowa. While at Palmer, Dr. Ruesch traveled on a mission trip to Manaus, Brazil to offer chiropractic care to underprivileged families that did not have access to any type of health care.

Dr. Ruesch discovered the amazing power of chiropractic from his own personal experience. As a child, he suffered from severe asthma attacks. After going through every treatment possible at that time, he thought he would have to rely on his inhaler for the rest of his life. A high school sports injury brought him to the chiropractor. After going through the recommended treatment, he found that he didn't have to use his inhaler as much anymore. No longer at the mercy of an inhaler, Dr. Ruesch attributes his healthier lifestyle to chiropractic and has made it his mission to help influence the lives of as many other families as possible in the same way.


Dr. Mike Croninger grew up in Oshkosh, WI. After graduating from the University of Wisconsin-Oshkosh with a Bachelor of Science in Biology, he attended Palmer College of Chiropractic in Davenport, Iowa. While attending Palmer, Dr. Croninger traveled on a mission trip to Hyderabad, India, to offer chiropractic care to underprivileged families that did not have access to any type of health care.

Dr. Croninger began chiropractic care after a low back injury during a sporting event. His experience not only helped with the low back pain, but also caused the headaches he experienced almost daily to subside. Dr. Croninger also noticed that his tinnitus (ringing in the ears) diminished while under chiropractic care.
