The Massachusetts Gaming Commission will begin looking for a new administrative head next week when Executive Director Edward Bedrosian leaves to pursue an opportunity in the private sector.

Deputy Director Karen Wells, who leads the commission’s Investigations and Enforcement Bureau, will serve as interim executive director while the commission searches for a replacement.

“I was privileged these past four years to work with great Commissioners, past and present, to help lead a talented team of professionals who worked hard every day to open and regulate casinos, to license and register people in a new industry, to ensure diversity in both the construction and operations workforces, to establish responsible gaming and research on the impacts of introducing casino gambling into Massachusetts, and to create a transparent and inclusive work environment,” Bedrosian said in a statement.
