954 Loop 337 New Braunfels, TX 78130

My banking career spans more than 15 years and includes experience in commercial and retail banking. I enjoy helping small business owners, real estate investors, and nonprofit organizations with their credit needs. I also enjoy helping individuals and families build their dream home. As a Lending Officer, I’m grateful to work for a bank with a straightforward business model, a client-focused philosophy, and an emphasis on doing the right thing.

I was born and raised in Austin, TX, but have called New Braunfels home for 14 years. I’ve enjoyed being a part of our flourishing community during that time. Outside of work, I like getting outdoors with my family, playing guitar, and traveling. I’ve served as a Treasurer for Scouts BSA for six years and am active in my local church.
