Charles Beier, D.D.S.
Doctor of Dental Surgery, University of Minnesota
Neurophysiology, Northwestern University
Dr. Beier, who prefers to be called Charlie – has lived and practiced in Payson since 1995 with his wife Amy. Charlie and Amy essentially moved to Payson on their honeymoon and have never wavered in their loyalty to this small town. Growing up in northern Wisconsin gave Charlie lots of opportunities to learn and appreciate many different walks of life. Charlie graduated with a neurophysiology degree from Northwestern University and went on to graduate with a DDS from the University of Minnesota. He and Amy immediately moved to Payson and the rest is history. Minneapolis straight to Payson takes a little getting used to! Charlie started his own practice in 1997. Charlie and Amy have two daughters and are dog parents to Labs. Charlie plays the saxophone, guitar and piano and enjoys cooking, gardening and hiking. Ethics and honesty are paramount to his philosophy.
