Linden studied philosophy and natural science at the University of North Dakota with the intent of becoming a medical doctor and helping people.  During his studies and searching himself, he chose to attend Chiropractic School instead of Medical School.  Primarily because medical doctors seemed very limited in their treatment of people, they were either putting something into people or taking something out to TRY and make them well.

​

Linden knew the body had the amazing ability to maintain health if it had everything it needs to do it.  Case in point, you cut your finger, the body gets to work ASAP to clot the blood, bring white blood cells there to kill any bacteria and starts to heal the cut.  The philosophy of Chiropractic (The Body Heals from the Inside Out), resonated with Linden and drew him to Chiropractic.

​
