About Diane

In 2007, Diane Donnelly formed The Donnelly Group to create an innovative team strategy that would provide clients with agents dedicated specifically to the unique needs of buyers and sellers. This approach allows each client to access the experience, expertise, and resources needed to successfully buy or sell a home.

It allows the agent(s) to focus all their efforts, training, and skills unique to each of these processes. This approach has been overwhelmingly successful! The Donnelly Group is consistently among the Top real estate teams in Maryland and recognized nationally.

In their spare time, Diane and the team devote a tremendous amount of time to dog adoption and transport services. She has volunteered time and resources to support the AA SPCA and the Senior Dog Sanctuary and transports dogs from high-kill shelters to foster homes for adoption.
