Connell Foley LLP is pleased to announce William J. Castner has joined the firm as a Partner.

“Bill Castner is an exceptional addition to Connell Foley,” said Managing Partner Philip F. McGovern Jr. “Bill has operated at the most senior levels of large corporations, health care institutions, and government. He is well regarded for his strategic insights and ability to problem solve on behalf of his clients. His record of providing sound guidance to Gov. Murphy as Senior Advisor on Firearms Policy, as well as his earlier success at both Horizon Blue Cross Blue Shield of New Jersey and Gibbons PC, will make him an invaluable member of our firm, particularly as we continue to grow our Cherry Hill office.”

Mr. Castner will practice primarily in Connell Foley’s Health Care Group. Drawing on his extensive background in the public and private sectors, Mr. Castner will provide strategic counsel to senior management and entrepreneurs throughout the region.

“I’m very honored to be joining Connell Foley, a firm that is well-respected and fast-growing,” said Mr. Castner. “I am eager to return to practicing law at one of the region’s most dynamic firms and with its extraordinary group of dedicated and skilled professionals. I am hopeful that my years of experience in government, along with my experience in the health care industry, will benefit clients and contribute to Connell Foley’s continued growth.”

During Mr. Castner’s tenure as Senior Advisor on Firearms Policy, the Governor was able to sign into law and advance some of the most progressive gun legislation in the country.

“Bill Castner has been a tremendous asset to my administration,” said Governor Phil Murphy. “I have come to count on Bill’s sensible advice and counsel. Although I’m sad to see him depart his Senior Advisor role with us, I’m pleased he will continue his work on gun violence prevention at Connell Foley. I know his new firm has gained a very smart and talented public servant.”

As a former Senior Vice President of Corporate and Regulatory Affairs at Horizon Blue Cross Blue Shield of New Jersey, Mr. Castner relied on his vast experience in dealing with complex health care and insurance regulations to help the company navigate a host of significant challenges while serving over 3 million members. His experience in the health care industry will further strengthen Connell Foley’s commitment to counseling health care systems, hospitals, health insurance companies, providers and nonprofits.
