About Robin

If you’re buying or selling in St. Mary’s County, Maryland, I offer local expertise you can rely on.

I’m a St. Mary’s County native and a two-time #1 Real Estate Agent in St. Mary’s (The Enterprise readers’ choice), with nearly 450 homes sold and $165M+ in closed sales volume. My business is built largely on referrals, which reflects a consistent, client-first approach.

My proven results in St. Mary’s County and Southern Maryland include 100+ homes sold in Leonardtown and nearly 100 in California, along with consistent activity in Lexington Park and Hollywood. I primarily serve St. Mary’s County, with additional experience across Calvert and Charles Counties.

I help clients navigate every part of the Southern Maryland market, including:

Leonardtown homes and historic properties
Waterfront homes in Piney Point and the surrounding areas
Rural and residential properties in Mechanicsville and across the county

Clients work with me for clear guidance, strong communication, and a steady process from start to close. Whether you’re relocating, upsizing, downsizing, or buying your first home, I focus on helping you make informed decisions. Many of my clients come through referrals, which reflects the experience I aim to deliver.

When it’s time to make a move in St. Mary’s County or Southern Maryland, you’ll have experienced local guidance at every step.
