Meet Sine

Sine Kerr (pronounced: SEEN-uh) has been married to her high school sweetheart, Bill, for 46 years. Together, they have four children and twelve grandchildren, all of whom reside in the West Valley.

From 2018-2025, Kerr served as the Arizona State Senator for Legislative Districts 13 and 25 (post-redistricting). Her districts included most of the West Valley and stretched all the way out to Yuma County, representing large agricultural areas and three major military installations.

Kerr was elected by her Republican colleagues to serve as Senate Majority Whip and also served as Chairman of the Senate Committee on Natural Resources, Energy, and Water.

In 2021, Senator Kerr was the author of SB1442, the legislative vehicle for Governor Doug Ducey’s Arizona Healthy Forest Initiative.

Kerr worked across the aisle in the Arizona Legislature to get a number of bills signed into law, including ‘Kayleigh’s Law’ in 2021 and the landmark ‘water protection’ bill in 2022.

In 2024, Kerr was the prime sponsor of the Arizona Women’s Bill of Rights, which protected women from biological men in locker rooms, bathrooms, and sports by changing state law to include only male or female as sexes. The bill was vetoed by Governor Katie Hobbs.

Kerr was inducted into the Arizona Outdoor Hall of Fame in October 2025 and has been recognized for her strong legislative work by a number of organizations, including the Greater Phoenix Chamber of Commerce and the Arizona Game and Fish Department.

Sine is a graduate of Buckeye Union High School in Buckeye, AZ. She moved to Buckeye with her family when she was three years old and has stayed in the community ever since. After graduating from high school, Sine and Bill (a third-generation farmer) got married a year later. They started their own dairy herd with 15 dairy cows in Buckeye. They grew and built their family-owned farm over four decades and now operate a small cow-calf operation and grow forage crops.
