Greenfield grew up on Long Island. He attended Oberlin College, where he was a National Merit Scholar and followed a pre-med curriculum before graduating in 1973. He applied unsuccessfully for medical school before deciding to go into business with Ben Cohen, a childhood friend.

The company, which sold to the British-Dutch corporation Unilever in 2000 has since opened almost 200 franchised shops and reports earnings of $237 million annually.
