Allan was born in Brooklyn, NY in 1938 to Frieda and Maurice Sexter. He grew up in Flatbush, Brooklyn with his sister Iris (Popkin). He developed a strong work ethic early in life, working various jobs as a teenager to help support his family. He attended Midwood High School, where he met Martha Helman, who would become his wife and life-long companion for 65 years.

He was a high school teacher in Brooklyn while attending Brooklyn College. After he graduated, he went on to earn his JD with honors from Brooklyn Law School. He then served as a clerk in the US District court in New York before going into private practice. He was a partner at the New York law firm Kimmelman, Sexter and Sobel, then a senior partner in the later iteration of the firm, Sexter and Warmflash. He finished his career working as Senior council for Millennium Partners, a New York-based hedge fund.
