Reisman was born in Cuba, New York, the third of five children to Lyle and Josephine Reisman. His father worked as a manufacturing specialist at Acme Electric Corporation. In 1969, the family moved to Lumberton, North Carolina. Reisman attended Lumberton High School where he was a multi-sport athlete, playing basketball under coach Bob Ivey. Shortly before his junior year of high school, Ivey accepted the coaching position at Florida Air Academy. Reisman followed his coach to the school and became a High School All-America in football and basketball. He played basketball and tennis at Coffeyville Community College before transferring to Pittsburg State University. Reisman graduated from Pittsburg State with a bachelor's in physical education in 1977.
Coaching career
After considering a career in medicine, Reisman began his coaching career as a volunteer assistant at Fort Scott Community College. He served as a graduate assistant at Arkansas State during the 1978-79 season before coaching two seasons at Trumann High School. In 1981, he was hired as an assistant at Southeastern Oklahoma State under coach Jack Hedden. Reisman was scouting at Cook County College when he noticed a young man named Dennis Rodman whom he thought had potential. After coming to another game, Reisman found out that Rodman had flunked out of school, so he called his mother after hounding the registrar's office. Despite showing little initial interest, Rodman was convinced to sign at Southeastern Oklahoma State in 1983 after Reisman mentioned a childhood friend of his attended the school. After a star career at the school, Rodman became an NBA Hall of Fame player. Reisman coached at Southeastern Oklahoma State until 1987, when he was offered the head coaching job at Connors Junior College. In his only season, he guided the team to a 21-10 record, with future NBA pick Anthony Jones as its star player. In 1988, a head coaching position had opened up at Tarleton State, a National Association of Intercollegiate Athletics institution that had one winning season before his arrival. Despite being told by university president Barry B. Thompson, "You don't have the to take this job," Reisman accepted the position and led the team to an 18-11 record his first season. Reisman claimed three straight Texas Intercollegiate Athletic Association titles, followed by two NAIA regional titles. He credits this initial success to the foundation of the Texan Club, a booster club for the athletic department. He was named assistant athletic director in 1989, and was named athletic director on September 1, 1993, following the resignation of Ron Newsome. In 1994-95, Tarleton State made the move to the NCAA Division II and the Lone Star Conference. During the 2001-02 season, Reisman guided the Texans to their first 20-win season as a Division II member. The following year, Tarleton state finished 29-4, won the LSC North Division Championship, and advanced to their first-ever Sweet 16. In the 2003-04 season, he won his first LSC Tournament title. He earned TABC Small College Coach of the Year, NABC Regional Coach of the Year, and LSC Coach of the Year honors in 2004. During the 2004-05 season, Reisman guided the Texans to their first Final Four appearance. Between 2010 and 2012 Reisman had two of the greatest defensive teams in NCAA Division II history, holding opponents to 53.3 and 56.3 points per game. His 2013-14 team began the season a school-record 18-0 and finished 28-3 and won the LSC regular season and tournament. In the 2014-15 season, Reisman guided the team to a school-record 31-4 record and he reached his second Final Four after defeating the University of Mount Olive in the Elite Eight. On January 2, 2016, Reisman won his 600th career victory, a 71-61 win over Cameron, and was presented with a proclamation from Texas governor Greg Abbott. In September 2016, Reisman underwent successful surgery to remove his prostate cancer. On March 23, 2018, Reisman announced he was stepping down as head coach in favor of his son, Chris Reisman. He finished his career with 691 career wins, with 654 of them at Tarleton, the most wins by anyone in Tarleton history. His record at Wisdom Gymnasium was 418-72, and his teams spent 128 weeks ranked in the National Association of Basketball Coaches poll.
Post-coaching career
After stepping down from coaching, Reisman continued as the athletic director at Tarleton State. On May 5, 2019, he was inducted as the 169th member of Tarleton State's hall of fame. On May 22, he hired Mike Sirianni as the seventh baseball coach in Tarleton State's modern history. Reisman presided at a ceremony in November 2019 to welcome Tarleton State's entry into NCAA Division I and the Western Athletic Conference starting the 2020-21 season. On March 30, 2020, Reisman hired Billy Gillispie, who formerly coached at Kentucky, as the next basketball coach at Tarleton State.
