Established in early 2023, The Mark Hennessy Foundation, Inc. (MHF) was created to honor Mark's wishes to support musicians on Cape Cod and beyond.  


Mark Hennessy was a resident and well-known musician on Cape Cod. Mark was influenced early on by the jazz musicians that played at his family’s restaurant, Hennessy's Steakhouse, in Dennisport, MA. He had an innate rhythm and love for music which he developed at a young age, picking up the guitar at age nine—and the music never stopped.


Mark built a career on Cape Cod doing what he loved—playing music. Mark’s bands included but were not limited to The Hennessy Brothers, Hen House, Tequila Mockingbird, and the Cape Cod Slackers. He had a way of moving those who had the honor of hearing him play, creating many friendships along the way. Mark played in just about every room on Cape Cod, eventually sharing his musical talent as far as Florida, Vermont and the Caribbean. Throughout his life, Mark supported musicians near and far and was always willing to lend a helping hand. Despite his humble demeanor, the world was Mark’s stage.
