An 11-year-old Reading brokerage is joining one of the state’s largest real estate agencies.

Berkshire Hathaway HomeServices Commonwealth Real Estate announced it had acquired the Dooley and Mason Realty Group on Monday. Dooley and Mason was launched in February 2008 by veteran realtors Judy Mason and Lisa Dooley, and served much of the North Shore and north metro and closed nearly 500 transactions and more than $200 million in sales volume.

“As the industry shifted, we realized we needed more to continue to deliver the quality service we were famous for. After a thorough search of our options, it became clear that Berkshire Hathaway HomeServices Commonwealth Real Estate was a perfect fit,” Dooley said in a statement. “It’s a big company with the small company feel, where everyone pitches in to help. We are so excited to become part of the Berkshire Hathaway HomeServices family. By joining Berkshire Hathaway HomeServices Commonwealth Real Estate, we gain global recognition with a brand that has all the modern tools, technology and resources that we can implement on day one to help grow our business and better serve our customers and clients.”

The group will remain at its Reading office.
