Dave Kerpen

After growing up in Brooklyn in a "typical dysfunctional Jewish" family, he went to Hunter College High School and then to Boston University. Kerpen began working as a vendor at Fenway Park in the summer of 1996, before his junior year at Boston University, and at the FleetCenter that fall, where he sold Crunch 'n Munch on commission. His sales routine of shouting, singing and dancing in the aisles earned him the nickname "the Crunch 'n Munch Guy". Clay Siegert of the Herald wrote in 1998 that the routine had made him "a local celebrity", and Richard C. Whiteley, in his 2001 book Love the Work You're With, wrote that Kerpen had "turned a routine sales job into high-flying, first-class entertainment".

After graduating from Boston University, Kerpen worked as a financial counselor at Merrimack Estate and Business Planning Group in North Andover, Massachusetts, while continuing to work as a vendor at night. He had joined the firm as an intern after its managing director saw him vending at a Bruins game in 1996.

As of 2025 Kerpen had lived in Port Washington, New York, for 16 years with his wife, Carrie Kerpen. On 8 July 2026, their 20th wedding anniversary, the couple officiated a vow renewal ceremony for more than a dozen couples at the Brooklyn stadium where they had married.

In 2008 Kerpen, then living in Little Neck, Queens, was a candidate for a New York City Council seat. He later served on the Port Washington Board of Education. In February 2025 he announced his candidacy as a Democrat for supervisor of the Town of North Hempstead, campaigning on revitalizing downtowns, government efficiency and a more "likable" town government. In the November 2025 election the incumbent, Jennifer DeSena, was re-elected with 55.62 percent of the vote.
