About Bill

I'm a DC native --I know these neighborhoods inside and out. After 18 years in real estate, I've learned that this business runs on two things: numbers and people. I came up as a loan officer, so I understand the financial side. But the real work happens when you sit down and listen to what someone actually needs.

My work extends from Frederick all the way to Fredericksburg. Whether you're relocating, coming home, or just ready for what's next, I'm here to make it straightforward and get you results.

Let me show you how I can help.

For buyers

Residential real estate is the business of numbers—and the science of people. Before we make an offer, we preview the process so you won't get blindsided. You'll know what to expect.

If you're relocating, my street sense gives you the edge. I know where the neighborhoods are headed, not just where they've been. Native to DC? We can find you something that actually fits.

I'll match you with the right lender. We'll have a plan B. And I'll keep this simple.

For sellers

Residential real estate is numbers. But it's really about getting your number right. We don't leave money on the table—we deploy preparation, visibility, and pricing strategies that trade above the line.

No nervous conversations. No second-guessing. Just a plan that works. I will protect your interests and deliver results.
