About Brian

The real estate process should be exciting—not overwhelming. I’m here to make the process smooth, informed, and even enjoyable. With clear communication, honest guidance, and a down-to-earth approach, I’ll help you navigate every step with confidence and peace of mind.
As a third-generation agent licensed since 2012, I’ve grown up in the industry and built a career grounded in service and results. My background spans everything from land development and new construction to market research, finance, and leading high-performing teams. That means I bring a deep, well-rounded perspective to every transaction—and every client.
Born and raised in Virginia, I know this market like home—because it is. Whether you're buying your first home or your forever one, I’ll be your advocate, your guide, and your go-to local resource. Let’s find the right home and the right community for you—and make the journey as rewarding as the destination.
