Senior Loan Officer

About me

I was born and raised right here in Montgomery, Alabama—and, for many years, I have taken great pride in helping families in my hometown navigate the home buying process with confidence and peace of mind.

As a local mortgage lender, I combine the strengths of building trust, networking, and educating. I strive to build deep, meaningful relationships that span past the closing table, and stay visible and engaged to serve as a reliable resource for clients and partners alike.

But at the core, I’m more than a loan officer—I’m your trusted local advisor. I’m here to guide you through the process, break things down clearly, and make sure you feel educated and confident every step of the way. Whether it’s your first home or your fifth, I’ll be in your corner, keeping it simple, steady, and focused on what’s best for you.

I bring that same mindset home with me. As a husband and proud dad to two little girls, I take family seriously—and I promise to take care of yours like I do mine.
