Board Chair

A former executive and financial expert with extensive nonprofit and corporate board experience, Bill has been guiding HPC through unprecedented growth as Board Chair since July 2021. He brings to HPC a unwavering commitment to excellence, and his service has inspired others to deepen their engagement with our Cape Cod community.

He also had extensive international duties as a PwC Global Managing Partner. After leaving PwC, he became CEO of Enterasys Networks. A resident of Orleans, Bill and his wife, Betty, enjoy an active life golfing, hiking, and relaxing on the Cape with friends and family.
