Susan M. Wismer[1] (born December 13, 1955) is an American politician and a former Democratic member of the South Dakota House of Representatives who represented District 1. Wismer was the Democratic nominee in the 2014 South Dakota gubernatorial election.
Susan M. (Jones) Wismer was born in Britton, South Dakota to Maurice and Dorthy Jones. She's the oldest of six siblings and grew up on the family farm in northeast South Dakota. She attended Britton Elementary and High schools (now Britton-Hecla) and graduated with a degree in English from Augustana College in 1978. After college she taught high school English for a year in Iowa. In 1979, Susan married Mark Wismer, also of Britton. She and Mark moved to Washington for his job, and she studied and became a certified public accountant. In 1983, Susan and Mark moved back to Britton with their newborn son, and continued to raise their children, three in all, in South Dakota close to family. Upon their return to Britton, Wismer and one of her sisters founded, and currently own and operate, Britton Bookkeeping and Tax Service. All of Wismer's children attended in-state universities.
Wismer has always been an active member of her hometown church, First Presbyterian, in Britton. She has served as an elder, vocal and bell choir member, Sunday school teacher and has volunteered her time to serve on many local and Presbytery-wide committees.
Many family members have been active in politics. Wismer's grandfather, Art Jones, was the first president of Basin Electric and a legislator. Her uncle, Curtis 'Curtie' Jones also served in the legislature from 1971 to 1986 and was a Regent on the South Dakota Board of Regents. As a high school student, Susan served as an intern in the South Dakota legislature. In 2008, once all of her children had graduated high school, she ran for the South Dakota House of Representatives to represent District One which include Roberts, Day, Marshall, and parts of Brown County. Wismer is now in her 3rd term (6th year). Wismer has served on the Appropriations Committee since the beginning of her legislative service. She is a current member of Government Operations and Audit Committee, and has served on the legislative redistricting and various summer study committees.
