Boston-based ad agency allen & gerritsen has acquired Neiman of Philadelphia to create a 200-staffer operation under the A&G name.

tim reevesNeiman chief Tim Reeves (pictured), a former reporter and communications director/press secretary for Pennsylvania Gov. Tom Ridge, will head a&g's PR and executive consulting units, becoming a shareholder and board member of the combined firm. He called both firms "fiercely independent," noting the merger idea came out of a meeting of the 4A's in May 2012.

Andrew Graff, CEO of a&g, continues in that title. He praised independent firms for their "agility and entrepreneurial zeal," and said the deal gives the combined agency the scale needed to innovate and expand.

Neiman was founded in 1980 in Harrisburg and counts the Commonwealth of Pennsylvania, Comcast, Temple University, Insight Pharmaceuticals and Sonoco among its clients. It has 55 staffers.

The firms say the combined entity is one of the largest 20 independent agencies in the country.

Weir Financial Services advised the firms on the deal. Financial details were not disclosed.
