About me

I’ve spent my life serving, building, and connecting.


From 1988 to 2010, I served in the U.S. Army on active duty and in the Reserve, including two overseas deployments. I then continued supporting our soldiers as an Army civilian employee, working in IT until 2025.


In Republican politics, I’ve been a precinct chair since 2014 — first in Bexar County and now in Guadalupe County. I’ve chaired Senate District conventions, served as an election judge, and been a delegate to every Republican Party of Texas State Convention since 2014. Along the way, I’ve worked with statewide coalitions and the Convention of States to advance priorities like ending taxpayer-funded lobbying and restoring accountability in government.


Beyond politics, travel has been a lifelong passion. I took my first cruise in 2001, and more than two decades later I’ve experienced itineraries from Alaska to the Caribbean and beyond. That love for travel led me to become a cruise travel specialist, helping families, couples, and groups plan trips that create memories to last a lifetime.


My wife, Jennifer, and I were married in 1991 while stationed together in Germany. Today we make our home in Guadalupe County, where family, service, and community remain at the center of everything I do.
