Foster has been married to his best friend and high school sweetheart Lauren, for eleven years. They have three children, Otto, June, and Clyde.

Duck hunting on the Cimarron River with his dog Rosco, friends, clients, and now his son brings much joy to his life.

At the core of all he does, is his unwavering faith and his relationship with God. Fosters desire is to give God the glory for all that all that God has enabled him to do both now and in the future.

Brennin Hayes was raised in Choctaw, Oklahoma before becoming a proud alumni for the University of Oklahoma. Prior to passing the FINRA Series 7 and 66 Security Licensing Exams, Brennin earned his bachelor's degree in economics as he worked for the OU Football Team as a Student Equipment Manager. Although not a job that was glorious in title, it was extremely necessary in practices and games. Players and coaches have always relied on team staff to make sure they are ready for the expected, and also the unthinkable. Brennin helps clients achieve the same readiness here at Cimarron Financial Group.

Brennin has transferred his knowledge, hard work, and responsibility learned from sports and team management into a financial advisor practice style that will benefit clients and Cimarron Financial Group families for years to come. Since working under a seasoned financial advisor for years before becoming one, he gained useful knowledge and insight that will help to reach clients goals. Our job, and ultimate goal, is to guide and protect clients' interests so that they can feel more financially secure while allowing them to take some weight off of their shoulders.

When not in the office, Brennin enjoys fishing, going to concerts, spending time with friends and family, along with hosting cookouts.
