Jay Poster was born October 16, 1954 in Brooklyn, New York. He grew up in San Diego, California.
Music brought Jay Poster to Las Vegas for a brief time in 1974. Jay wanted to pursue a musical career and his cousin was a professional musician with the Nat Brandwynne Orchestra at Caesars Palace. Poster left Las Vegas to return home to San Diego and his studies at San Diego State University. It would be over a decade later before Jay returned to Las Vegas to live and this time it became permanent.
He was good at sales and his day job selling office furniture offered him the opportunity to transfer to Las Vegas in 1986. Within a few years, however, it was a recruiter for Palm Mortuaries who introduced Jay to his defining career moment and to Allen Brewster, a prominent Jewish leader and founder of King David Cemetery and Mortuary. Poster has been general manager of King David Cemetery and Mortuary in Las Vegas, Nevada since 2001.
Jay keeps his music alive with participation in the Shabbatones at Congregation Ner Tamid and Desert Winds, a community based performance organization.
