Get to Know Me

In Barb's previous role as the Chief of Staff to a Fortune 5000 company, she learned how to outpace and stay one step ahead of clients to create a solid plan for communicating with her clients. This plan has served everyone well in the demands of a real estate transaction. 
 
Barb has facilitated over 50MM in real estate transactions, which means she knows how to get your house listed for the best ROI, negotiate on your behalf, and how to guide you in the home-buying process. 
 
Barb and her husband Brad, along with their 4 kids, have lived in Carroll County, Maryland, for over 20 years and love the quiet living in the county. They work as a team operating their brokerage and going above and beyond for their clients as well as renovating properties themselves!
 
On the weekends, you’ll find her watching her boys play football, making healthy recipes, hosting friends for dinner, and keeping up with their pit bulls!
