Born in North Miami, Florida, Adam is the younger brother of artist and actor Shepard Koster. His mother Ruth and father Abraham encouraged him to pursue acting when he played Walter Hollander in Woody Allen's play "Don't Drink the Water" at North Miami Beach High School. His father Abraham is a classical violinist from The Bronx, and a well known cantor. Adam played baseball as well as performing in theatre in high school and then attended the University of Florida, where he and his brother both walked-on to the top-ranked baseball team, two years in a row. After moving on from baseball because of injury, Adam began surfing and became a video jockey during the early years of MTV, at a low power TV station in Alachua County called TV69, run by Tom Zingale Sr. and Bill Cosby, the comedian. A member of Tau Epsilon Phi fraternity, Adam got to coach intramural football and act in community theatre including productions of "Don't Be Afraid of the Dark" and as Prince Philip in "The Lion in Winter", directed by then-girlfriend and soon to be Dean of Theatre and Education at Southwest Louisiana State University, Rebecca Tomlinson. After college, Adam worked on cruise ships as an entertainer and host, then worked in Miami theatre as an actor and sound and light technician as well as carpenter. He landed a role as "Young Waiter" and understudy to Happy and Bernard in the National Tour of Arthur Miller's "Death of a Salesman" with Hal Holbrook and Elizabeth Franz (who won the Tony the next year). The tour was planning to go to Broadway and received notes from Miller himself, who visited the production in Miami and in Boston. Adam also fell for Hal's daughter, Eve - a talented actress and granddaughter of award winning writer/director Robert Rossen. After the split, Adam moved to Los Angeles where he continued to act, write and produce television. He has worked as a story producer and has written numerous short stories and screenplays.
