In the wake of the mammoth merger between DuPont and Dow Chemical Co., TruMark Financial Credit Union is taking care of the financial affairs of the chemical maker’s employees.

TruMark has just acquired Dow Northeast Employees Federal Credit Union, which has offices in Collegeville and Center City, according to a Philadelphia Business Journal report by Jeff Blumenthal.

Dow Northeast’s $21 million in assets join the $1.8 billion in assets of TruMark and its 22 branches across the region, including six in Montgomery County. TruMark also recently moved its headquarters from Bucks County to Fort Washington.

Acquisitions are nothing new to the region’s third-largest credit union, though. TruMark has acquired nine other institutions in 10 years, most recently taking over nearby Keystone Federal Credit Union.
