About Keith

A Loan Officer Who Actually Works for You

I'm Keith Sullivan, a mortgage loan officer and U.S. veteran passionate about helping individuals and families achieve their homeownership goals across the Dallas–Fort Worth metroplex and beyond.

Whether you're a first-time buyer navigating the process for the very first time, a fellow veteran using your VA benefit, a seasoned investor expanding your portfolio, or a homeowner looking to refinance, I bring personalized guidance, competitive rates, and a commitment to getting you to the closing table.

I believe buying a home should feel exciting — not overwhelming. My job is to make the process transparent, smooth, and tailored to your unique situation.
