In the wake of its $1.2 billion acquisition of Beneficial Bancorp Inc., WSFS Bank has hired Lisa Washington as its first chief legal officer and senior vice president. 

Washington is based in Philadelphia and oversees the bank's enterprisewide legal operations. She reports to Paul Greenplate, executive vice president and chief risk officer of the bank, which is headquartered in Wilmington, Delaware. 

Greenplate said in a written statement that the bank has "expanded and grown significantly in recent years," and "Lisa will further bolster our legal team, and her expertise and leadership will help us meet the growing needs of our organization."

The bank announced Washington's hiring Thursday. Her start date was Sept. 16, according to a WSFS spokesman. She was not available for an interview. 

In March, the bank's parent company, WSFS Financial Corp., finalized its acquisition of Beneficial Bancorp and its primary subsidiary, Beneficial Bank. Now operating as one company, WSFS has more than $12 billion in assets. 

Washington arrived at WSFS, which is known as "Wiss Fiss," after having most recently served as vice president, CLO and corporate secretary of Atlas Energy Group, a Philadelphia-based energy management company that acquires and develops oil and gas assets.

She's spent the past 13 years with Atlas and its predecessor companies and was a member of the firm's executive management team. She oversaw all legal, corporate governance and compliance issues for the firm. 

Prior to Atlas, Washington was in private practice in Philadelphia, first as a litigation associate at Fox Rothschild and later as a corporate associate at Blank Rome. 

She is a graduate of Princeton University, the Wharton School of the University of Pennsylvania  and the University of Pennsylvania Law School.
