Sharon (Kalscheuer) Peterson was born September 8, 1942 in St. Cloud, Minnesota to Leo and Myrtle Kalscheuer. Sharon graduated from Roosevelt High School in Minneapolis and earned a bachelor's degree in psychology from the University of Minnesota. She leveraged her degree in psychology first as a stay-at-home mother and later leading a recreational program for developmentally disabled adults, as a case worker for Big Brother/Big Sister, and as Guardian Ad Litem for abused children. She was consistently an advocate for the disadvantaged, also volunteering regularly in the public school and in annual holiday gift drives. She is survived by one brother, Wallace Kalscheuer of Minneapolis, and two children: Michael Peterson and his family, Melissa, Nolan, and Ryan of Owatonna; and Michelle Clark and her family, Joel, Nina, and Tessa of St. Louis. Sharon was preceded in death by her husband, Jerry Peterson, and her son, Matthew Peterson.
