About Don Mayhew

Don Mayhew is a lifelong rural Missourian, engineer, and small-business owner who has spent seven years advocating for Missouri families in the House of Representatives.

After graduating from high school, Don attended the University of Missouri–Rolla, where he became a licensed Engineer and Surveyor. He and his wife, Deanna, have been married for 39 years, raising four children and now enjoying eight grandchildren.

Before serving in the Missouri House, Don was elected by his community to the local school board and as Pulaski County Surveyor, working hands-on to solve real problems. He didn’t come to Jefferson City to be a career politician, he came to get results.

As the only engineer in the Missouri House, Don brings a practical, common-sense approach to government. He currently serves as Chairman of the Corrections and Public Institutions Committee and Vice-Chairman of the Appropriations Subcommittee overseeing Public Safety, Corrections, Transportation, and Revenue. He also holds leadership roles on Government Efficiency and Rules, helping cut waste and keep state government accountable.

Don’s work touches nearly every part of state government, budgeting, transportation, public safety, agriculture, economic development, and fiscal oversight, always with one goal: protecting taxpayers and strengthening Missouri’s future.

Don knows Missouri families are hurting. Overregulation from Jefferson City is squeezing small businesses and family farms, raising costs and killing jobs. Don is committed to shrinking government, cutting waste, and keeping more money in your pocket.

He is a strong defender of free speech, the second amendment, religious liberty, and the sanctity of life, believing every human life is precious. An avid outdoorsman and proud NRA member, Don stands firm for Missouri values.

Don Mayhew believes in common-sense, conservative solutions, and he would be honored to earn your vote for State Senate, in 2026.
