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 also 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 also 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, the Senior Dog Sanctuary, and transports dogs from high-kill shelters to foster homes for adoption. So, we are truly the dog-friendly Realtor, devoted to "Finding Dogs, and their Owners, a place to call home for Over 25 Years!"

    Diane Donnelly President, Seller's Division

    Diane Donnelly serves as President of The Donnelly Group with primary responsibility for the Seller’s Division. With more than 25 years of experience, her knowledge and expertise extend well beyond real estate.

    Diane’s career began in the lending industry first as a loan processor and then a loan officer. This experience gave her very unique perspective on the intricacies and challenges required to move a home through the buying and selling process from a financing perspective. This experience is one of the primary reasons Diane is able to navigate a sale forward when her counterparts are standing still. Diane later went on to work with a national builder and won a variety of awards and acceptance into the Burgundy Club (a prestigious achievement for the top 10% of the salespeople of the company). Diane continued to excel and was promoted to various leadership positions in Sales Training and Sales Management.

    In 2007, Diane formed The Donnelly Group with the goal of providing clients with a unique team strategy – allowing clients to access full-time dedicated agents in buyer or seller divisions. This business model offers agents that are experienced, trained and dedicated specifically to the unique needs and negotiation requirements for buyers vs. sellers.

    “We work with people at very joyful and sometimes very stressful times in their lives. We recognize how life-changing the home buying or selling process can be. We have helped people buy their very first home, sell a home after a death in the family; buy a bigger home for a growing family or downsize due to divorce. No matter what the situation, we go to great lengths to understand the ideal situation for each client and help them achieve their goal. We treat every client with dignity, respect and integrity. That may sound like a no-brainer, but it’s commonly overlooked in our industry,” commented Diane.

    Diane is an expert negotiator and committed to effectively communicating with her clients throughout the entire process.

    Diane volunteers her time, throughout the year, as a guest speaker for local workshops dedicated to educating home owners on the best ways to sell their houses and gain the most from their investment. Diane is also a photographer, boater and nature lover!
