David Olsen is a longtime resident of Downers Grove with a passion for serving his community. David grew up in the 81st district and attended local public schools, so he knows firsthand the challenges our schools face and how with the right policies they can thrive. After graduating from Downers Grove South High School, he attended the University of Illinois at Urbana-Champaign, where he earned a degree in finance and management. At the University of Illinois, he became Student Body President and was a Rhodes Scholarship finalist.

After receiving his degree, David returned to his hometown and in 2013 was elected to the Downers Grove Village Council where he ultimately was selected to be Mayor Pro Tem. David was also called to serve on the College of DuPage Board of Trustees as Vice Chairman during a tumultuous time for the institution. His leadership allowed critical reform efforts to proceed, kept taxes and tuition flat, and refocused the College on its core mission of providing accessible education.

Apart from his elected positions, David also serves on the Board of Directors for the District 58 Education Foundation and is an active member of Chamber630 which primarily serves businesses in Downers Grove and Woodridge. David belongs to Friendship United Methodist Church of Bolingbrook where he has served as co-leader of the eighth grade confirmation class and a member of the Chancel Choir and Bell Choir. He also serves as committee chairman for affiliated Boy Scout Troop 35.  

David works as an ethics & compliance officer. In his free time, he enjoys jogging at local parks, reading anything he can get his hands on and fixing up his recently-purchased 1928 Downers Grove home.
