Experience

27 years in real estate, close to 1,000 homes sold, serving the DC metro, Maryland, and Virginia. That experience plays out one conversation at a time. I have worked with homeowners going through a downsize, families selling an inherited home,and people who simply want to know what their options are. The work I do every day with real clients is what this site draws on.
