He is the host of "The Sam Greenfield Show"; which is an afternoon drive time talk radio show on WEVD 1050 AM in New York City. He masterfully blends comedy and politics, and uses rapid-fire, hard-hitting sarcasm to get to the truth and the funny bone at the same time. Sam's as likely to be seen on CNN's "Talk Balk Live" as he is on Comedy Central.

Sam is one of the few male comics to perform on Lifetime's "Girl's Night Out", and one of the few white comics to grace "Showtime at the Apollo"
