The Massachusetts Convention Center Authority’s (MCCA) newly minted executive director David Gibbons made two key senior executive decisions by naming Fred Peterson as the new deputy director and Dennis Callahan as the general counsel for the organization.

Peterson served as the interim executive director from July 1-Dec. 31, 2015, while also fulfilling the duties of director of facilities operations. Callahan, similarly, assumed the role of interim general counsel as well as assistant secretary to the board of directors in July 2015.

“I am eager to begin working with these two proven leaders in their new roles,” Gibbons said. “Both men possess skills and abilities that are difficult to find. We are fortunate to have them in these roles. I congratulate them on their well-deserved promotions.”

The Massachusetts Convention Center Authority owns and oversees the operations of the Boston Convention and Exhibition Center, the John B. Hynes Veterans Memorial Convention Center, the MassMutual Center in Springfield, Mass., and the Boston Common Parking Garage.
