Senator Markwayne Mullin is a successful business owner, working cow-calf rancher, and proud husband of 27 years to Mrs. Christie Mullin, and together the two are parents to six wonderful children: Jayce, Jim, Andrew, Larra, Ivy, and Lynette.

Mullin was sworn into office on January 3rd, 2023, following ten years of service to Oklahoma in the U.S. House of Representatives. A lifelong Oklahoman, Senator Mullin grew up on his family’s ranch in Westville where he and his family still reside to this day.

A graduate of Stilwell High School, Mullin went on to attend Missouri Valley College on a wrestling scholarship until the age of 20 years old. At that time, Senator Mullin’s father, Jim, fell ill, and Mullin and his recent bride Christie postponed studies to save the family business, Mullin Plumbing.

Over the past 27 years, Markwayne and Christie Mullin have expanded Mullin Plumbing to become the largest service company in the region, and along the way founded numerous other successful companies ranging from Mullin Environmental to Rowan’s Steakhouse, the latter a bustling restaurant in the neighboring town of Stilwell and named for Christie’s family.
