Pittsburgh-based Gatesman is doubling its size with acquisition of marketing communications firm Noble Communications.

The deal boosts Gatesman’s employee headcount to more than 125 and adds offices in Chicago and Springfield, Mo.

John Gatesman will serve as CEO of the combined entity, and Shannon Baker will remain president.

Noble Communications management team will remain in place as part of Gatesman.

Bob Noble will continue to lead The Food Channel, which was not part of the acquisition. His focus will be growing and expanding food publishing and Noble’s food marketing, which remains in Springfield.

Gatesman opened its doors in 2006.
