MY COMMITMENT
My commitment is simple, to serve District 6 with honesty, sound judgment, and respect for the people who live here. Every decision I make on the County Commission is guided by what is best for our community today and in the years ahead.
I am committed to responsible budgeting, strong public safety, protecting our schools, addressing traffic and infrastructure needs, and ensuring growth is managed in a way that preserves the character of our neighborhoods. I believe county government should be transparent, fiscally responsible, and focused on delivering real results for residents.
As a County Commissioner, I will continue to listen, ask thoughtful questions, and work toward practical solutions that reflect the values and priorities of the people I represent. My goal is to help keep Williamson County safe, well managed, and a great place to live.
