Board of Directors


Zachary Baeseman, MD - President

Zach Baeseman 2021
Zach grew-up in Edgar, a rural village in the north central Wisconsin. His home town has no stop-and-go lights, no fast food, and the largest employer in town is K-12 Public Schools (all in one building). He earned his undergraduate degree from St. Norbert College in DePere, WI, studying biology, chemistry, and philosophy. At St. Norbert College Zach played football and sang in the school’s Chamber Choir.

Zach attended medical school at the University of Wisconsin School of Medicine and Public Health in Madison, WI. Zach is a firm believer that physicians hold an obligation not only to their patients, but to their community. Consequently, he took an extra year to obtain a Master of Public Health in Madison, WI. He focused his graduate research on rural healthcare and the health assessment of rural Wisconsin.
