My goal is to provide information and an appropriate level of guidance to the patient so that they understand what the underlying issue(s) is(are) and so they can make an informed decision. My main goal is to empower and inform patients to make their own decisions. I generally think that less is more when it comes to medications, testing, etc.


Dr. Tinjum is married with two daughters and three miniature dachshunds. In his spare time, he enjoys cooking and all sports, especially running, hiking and golf.

Dr. Tinjum chose the healthcare field because he enjoys spending time with and talking to patients. He enjoys the challenge of medicine, and helping patients with their medical concerns.
