Meet the board


Bill Heitzman, President
Bill Heitzman, ADT, currently practices at True North Community Dental Clinic located in Shakopee, Minnesota. This newly formed clinic uses an innovative model featuring an advanced dental therapist as the primary care provider working under general supervision of the collaborating dentist.  The clinic exclusively serves patients who are insured through Minnesota Health Care Programs or are uninsured. 

Before that, he practiced in rural Grand Marais, Minnesota.  As he lived and worked, he found a sense of satisfaction by making relationships and providing care in the community.  He also participated in research made possible by the Delta Dental Foundation of Minnesota documenting the impact of integrating a dental therapist into a solo rural private practice.  Another contribution he made was with the Oral Health Task Force, a local non-profit that won the MDH Rural Health Team award for its efforts to improve the oral health of children through community oral health efforts. 

He earned his Master’s degree in Dental Therapy from the University of Minnesota School of Dentistry in 2012 after working in industry and as a teacher.

Some of his favorite things to do in life are to bike to work, drink really good coffee, spend time with his family doing anything and everything active.
