Rosemary Bayer

Michigan State Senate District 13

Rosemary Bayer is an engineer and lifelong Michigander. In 2018, she started knocking on doors, introducing herself as a local engineer who wanted to stand up to an out-of- touch administration and fight for the hardworking people of District 12. She won the election, flipping her district from red to blue for the first time in many, many years.

Prior to taking office, Senator Bayer spent many years in the tech industry. She serves on the board of directors for NEW, Solutions for Nonprofits and the SheHive, a women’s collective offering programs to empower women. She also co-founded the Michigan Council of Women in Technology, a nonprofit that provides STEM support and educational programs for girls and women around Michigan. She co-founded and served as Chief Inspiration Officer of ardentCause, a database technology company serving schools and nonprofit organizations and was named a Notable Woman in Tech by Crain’s Detroit Business in 2018.

Since taking her seat, Senator Bayer has served on the Senate Appropriations Committee and Appropriations Subcommittees for Environmental Quality and DNR, the School Aid Fund and MDE (where she is Minority Vice-chair), and the Infrastructure and Transportation sub-committee. She also serves on the Environmental Quality Committee as Minority Vice Chair. She is Chair of Michigan’s legislative Firearm Safety and Violence Prevention Caucus, and Vice-chair of the Poverty and Homelessness Caucus. With a knack for both numbers and mediation, she’s been a key member of several bipartisan budgeting efforts.
