Four months after joining Mon Valley Alliance, Ben Brown will be its leader.

Brown, an East Washington resident, will be the new chief executive officer of the Charleroi-based organization. He succeeds John Easoz, who had been acting CEO since the January resignation of Chris Whitlatch.

MVA’s board of directors, chaired by Easoz, unanimously selected Brown at its April meeting. He will assume his new duties Wednesday.

“I am excited about the . . . opportunity to become one of the leading organizations in our region creating economic development and jobs for the Mon Valley communities,” Brown said in a statement. “I look forward to what we can accomplish together.”

The alliance hired Brown in early January for the newly created position of director of operations, his current job. Before that, he was vice president of real estate for Beynon & Co., a commercial real estate firm based in Pittsburgh that is more than a century old. In recent years, he assisted MVA in its land sale at Alta Vista Industrial Park in Fallowfield Township.

Since mid-October, one company broke ground for a new regional headquarters and two other firms purchased lots at Alta Vista.

“We were very fortunate that we had such a qualified candidate already on our team,” Easoz said in a statement. “We are glad to be able to hand the reins to Ben.”

MVA was formed three years ago as a consolidation of Mon Valley Progress Council and Middle Monongahela Industrial Development Association. Each of the latter organizations had existed for 50-plus years.
