William R. Sasso

Chairman Emeritus


William Sasso


William Sasso served as Chairman of Stradley Ronon’s management committee and board of directors for 27 years, ending on January 1, 2021. He currently serves as Chairman Emeritus of the firm. The transition to Chairman Emeritus took place as a result of his desire to spend more time with his clients, and in his political and community activities. As Chairman, he was responsible for oversight and management of more than 200 attorneys in the firm’s eight offices in Philadelphia and Malvern, Pennsylvania; Wilmington, Delaware; Cherry Hill and Newark, New Jersey; Washington, D.C.; Chicago; and New York.

During his 50-plus years of experience, he has counseled privately and publicly held companies and religious and nonprofit organizations in various matters, including general corporate and securities law, mergers and acquisitions, health care, education, medical devices, tax and real estate.

Given that Mr. Sasso recognizes the importance of fair, bipartisan and good government, as well as the fact that many of the firm’s clients operate in areas of heavy governmental regulation, he has been involved politically for several decades. For example, he was asked in November 2022 to become the Chairman of the Board of the Transition Team for the Governor-elect in Pennsylvania, Josh Shapiro. In addition, after the November 2016 election Mr. Sasso was asked by then Attorney General-elect Josh Shapiro to serve as senior counsel to his transition team. He was also appointed by Pennsylvania Gov. Tom Wolf to serve on the board of Independence Blue Cross. He was appointed by former Pennsylvania Gov. Tom Corbett as Chairman of the Pennsylvania Infrastructure and Investment Authority (PENNVEST) and as a Commissioner of the Delaware River Port Authority, an office he held until 2015. He was asked in 2010 by then-Governor-elect Corbett to co-chair his Transition Team in preparation for taking office in January 2011.
