As the president of Alloy Entertainment (and its predecessor, 17th Street Productions), Leslie Morgenstein has been the key player and strategist in transforming the company's acquired published works into productions for the big and small screen since 1999. With an undergraduate degree in writing (from Sarah Lawrence College), a masters in English and creative writing (from the City College of New York), and an MBA in finance (from NYU's Stern School), he has combined his education and talent in both the artistic and business fields into a highly successful entertainment career as an executive producer. His first major break came with the screen adaptation of Ann Brashares' hugely popular teen novel "The Sisterhood of the Traveling Pants" in 2005, followed by its sequel in 2008. His focus then moved to television, where he served as executive producer on the short run of "Samurai Girl." Sticking with the teen novel formula, Alloy began buying up the rights to many successful young adult book series adaptations including "The Clique," "The Vampire Diaries," "Gossip Girl," and "Pretty Little Liars," which he then brought to the small screen.
