Mr. Greenfield changed careers to become an attorney after his return to New York in 1991, after his divorce in Virginia. He sought assistance of the courts, and only found it made his problems worse, not better. The Courts and other agencies treated him poorly because he was a father and they would not listen that he had (and still has) custody. Later, the Courts went after his x-wife for things she never did. When Mr. Greenfield called the courts and other agencies, and was told to just laugh at her like others would in his shoes. They also told him that he was petty when he requested the child support order be corrected to identify him as a man and his x as the woman. Mr. Greenfield, on the suggestion and urging by the Hon. Burton S. Joseph, changed his career path, retuned to college and then attended law school.

While hosting the talk radio show, "The Unfamily Hour," as "Mace in your Face," in the early 90's, his friends told him they heard Howard Stern talk about him on more than one occasion. He did not believe his friends and told them "!@#$ yourself." Then during the second week of law school in 1994, he was outside smoking a cigarette (he has since quit) and a young lady from his class approached him and said 'you look familiar, your voice is familiar, you're not that guy Howard Stern talks about, the other guy on radio Mace in your Face who disses the judges, DAs, cops and lawyers with impunity, those before him had their lives destroyed?' Struggling to keep his composure finding out his friends were not merely goofing on him as he prior thought, he tried to act cool and said: "yep, that's me."
