Philadelphia office


MPI, a prestigious national consulting firm founded in 1939 specializing in business valuation, litigation support and corporate advisory work, has opened a Philadelphia office to serve as national headquarters for its new forensic accounting and economic damages practice.  MPI’s Philadelphia office will also support its growing Pennsylvania client base, as well as its traditional business valuation and litigation support services.

Leading the Philadelphia office will be Mark Lingerfield, ASA, a Partner and Director at MPI responsible for business development strategies in the Mid-Atlantic region; Managing Director James T. O’Brien, CPA/CFF, who joins MPI from the Philadelphia office of an international public accounting firm where he was part of a National Forensic, Litigation and Valuation Services Group; and Vice President Megan B. Gilberg, CFE, CVA, whose practice is focused on disputes in matrimonial litigation and complex commercial litigation engagements.

“Our expansion into Philadelphia’s vibrant business community is a further broadening of MPI’s already strong presence in the Northeast and Mid-Atlantic markets,” says Dan Kerrigan, President of MPI.  “We are particularly happy to have Mark and Jim leading this effort, and serving as the faces of MPI to the Philadelphia legal and business communities.”

“Litigation support and dispute resolution services continue to be a growing part of MPI’s practice, and we are so very pleased to expand our firm’s expertise into the forensic accounting and investigation realm with the addition of Jim O’Brien,” adds Kerrigan.  “Jim is a highly regarded and nationally recognized litigation expert and has serviced the Philadelphia region for the entirety of his career.  In addition, we are proud to have Megan’s diverse valuation and forensic accounting expertise to help expand our Philly presence in both the commercial damages and marital dissolution markets.”

Headquartered in Lawrenceville, NJ — with offices in New York City, Boston, Connecticut, Chicago and Orlando — MPI and its staff of senior professionals has a stellar history and national reputation as a leader in the valuation and dispute resolution communities.

In April, MPI expanded its Matrimonial Litigation practice with the hire of Stacy Statkus as a Senior Vice President in the New York City office.  Her area of expertise within Litigation Support is Matrimonial Litigation involving high net worth individuals, celebrities, professional athletes, C-suite executives, business owners and their spouses.  Prior to MPI, she was Director of Litigation and Matrimonial Services for an international public accounting firm in New York City.
