| Collapse all
- I am the only candidate for Texas U.S. House District 21 and one of the very few candidates anywhere in this country who stood in uniform when America was attacked on 9/11. I was on Active Duty as a U.S. Navy Intelligence Specialist when the towers fell. When my service ended, I didn’t walk away from the fight I went back to the war zone in Iraq as an intelligence contractor. I ran toward danger, not away from it, because when this country is under threat, Americans step up. That is who I am, that is how I serve, and that is how I’ll fight for you in Congress.
- As a Veteran, I’ve learned what service, sacrifice, and dedication truly mean, and I bring that same commitment to public leadership. As a CEO, I understand how to manage resources wisely, solve complex problems, and make decisions that deliver results, not just promises. As a family man, I’m grounded in the values of integrity, compassion, and long-term thinking, because every decision affects not just today’s challenges but the world our children will inherit.
- My background has given me a balanced perspective, the strategic mindset to lead, the practical experience to manage, and the personal motivation to build a stronger future for all.
