Cournoyer was born on July 24, 1970 in Dallas, Texas, and earned a bachelor's degree in computer science from the University of Texas at Austin in 1992. She began her career as a senior consultant at Andersen Consulting before starting her own web development business, which she ran for more than 20 years. She has also worked as a substitute teacher, taught robotics and coding to students, and served as a reserve sheriff's deputy in her home of LeClaire in eastern Iowa.
Cournoyer served two terms as president of the Pleasant Valley Community School District Board and was elected to the Iowa State Senate representing District 35 (Clinton, Jackson, and Scott counties) in 2018, winning reelection in 2022. As a senator she chaired the Education Budget Committee, served as vice chair of the State Government Committee, and authored Iowa's landmark data privacy law. She also voted for a 2023 bill removing the State Auditor's ability to take state agencies to court to compel records. In December 2024, Gov. Kim Reynolds appointed her Iowa's 48th Lieutenant Governor after Lt. Gov. Adam Gregg resigned to become CEO of the Iowa Bankers Association.
Cournoyer filed to run for State Auditor on April 28, 2025 and was endorsed by Gov. Reynolds the same day. She defeated Iowa County Supervisor Abigail Maas in the June 2, 2026 Republican primary with 54% of the vote.
Positions herself as an "iron-clad" taxpayer watchdog and "true fiscal conservative," pointing to her school board record lowering the tax levy 41 cents and her Iowa Senate work on a $200 million government realignment as evidence of her approach. Frames the office as an instrument for reducing Iowans' overall tax burden, particularly property taxes.
Draws on her computer science and consulting background to argue for integrating artificial intelligence into audits, enhancing Iowa's transparency portal, and making the office "a home for recommendations from the Governor's DOGE Task Force" on modernizing government operations.
Cournoyer's central critique of current Auditor Rob Sand, whom she has described as running the office as a "political weapon." Cites in particular Sand's audit of Iowa's Education Savings Account voucher program, and pledges to prioritize transparency, efficiency, and results over headlines and partisanship.
