George Nessman

On July 1, 2014, Nessman became athletic director at Justin-Siena High School in Napa, California. Nessman on his hiring as Athletic Director, “I think there’s been some outstanding success here. It’s an outstanding place with a real important mission — to serve students and young people. I want athletics to reflect that." In Nessman's first year as athletic director, the Justin-Siena varsity football team won the CIF North Coast Section Division 4 championship.

In earning a berth to the 2011 College Basketball Invitational, Nessman became the fourth basketball coach at San Jose State to lead the team to the postseason. The 17 wins for the 2010-11 season were the most for the Spartans since 1980-81. Bowen signed Nessman to a new three-year contract following the season. However, San Jose State fell to 9–22 (1–13 in WAC play) in the 2011–12 season. In the 2012-13 season, after a 9–6 start, San Jose State finished 9-20 (3–14 WAC) following the suspension of leading scorer James Kinney. On March 13, 2013, athletic director Gene Bleymaier, who succeeded Bowen in 2012, fired Nessman.

In the 2013–14 school year, Nessman was a junior varsity boys' basketball assistant coach at the Harker School in San Jose. Harker JV finished 18–5.

Under Nessman, San Jose State reported five consecutive years of rising four-year average Academic Progress Rate (APR) scores, including a program-best 940 in the 2011–12 season (because of a perfect one-year 1000 score). However, the APR fell below 930 for the 2012–13 season, Nessman's last as head coach. As a result, the NCAA imposed sanctions on the San Jose State men's basketball program in April 2014 for the following season, including a postseason ban and reduced practice time. Athletic director Gene Bleymaier stated in response to the sanctions: "Last year, we were faced with a situation that needed to be dealt with in a major fashion. The coaching staff was not retained, and several players were not invited back for the 2013-14 season. Only four players returned from the 2012-13 team.

In 2008-09, Nessman led the Spartans of San Jose State University to the most WAC road victories in eight seasons.

San Jose State University appointed Nessman as men's basketball head coach in March 2005, and Nessman was the only WAC coach with two master's degrees. The San Jose State Spartans finished the 2004-2005 season with a 6-23 overall record under coach Phil Johnson. San Jose State's athletic director at the time was Tom Bowen, who was previously athletic director at Concord's De La Salle High School when Nessman was varsity basketball coach there.

Nessman's first season was the first time the Spartans signed a player directly from a San Francisco Bay Area high school in 21 years. The Spartans finished 2005-2006, Nessman's first season, 6-24 (2-14 in Western Athletic Conference play), and Nessman signed three more Bay Area players to the team for the following season. Although SJSU finished 2006-2007 only 6-24 (4-12 WAC), San Jose State extended Nessman's contract, originally set at four years in 2005, for two more years through the 2010–11 season. The Spartans followed up with a 14-19 (4-12) record in 2007-2008, the best team record in 14 years. In 2008, the NCAA reduced the number of scholarships for San Jose State men's basketball by two, as a result of an unsatisfactory four-year Academic Progress Rate of 886 (the minimum satisfactory APR is 925) that spanned predecessor Phil Johnson's final two seasons (2003–04 and 2004–05) and Nessman's first two seasons.

Nessman returned to his alma mater UC Berkeley for the 2004-2005 to be an assistant coach and recruiter for the California Golden Bears men's basketball team.

Nessman left the coaching position to become an academic advisor for athletics from 2001 to 2002 and then became head basketball coach of Bakersfield College for two years until 2004. Bakersfield went 30-32 under Nessman.

In November 2000, the state Commission on Athletics placed Porterville on probation for a season due to improper benefits provided to men's basketball players. The next month, Nessman became interim head coach for Porterville's women's basketball team.

Next, Nessman coached basketball at the community college level. From 1993 to 2001, Nessman coached basketball at Porterville College and was also athletic director at the school from 1995 to 2001. During his eight seasons there, the team went 188-68, including a 33-4 state championship season in 2000, when Nessman was named California Community College Coach of the Year. Porterville had a 40-game win streak from January 2000 to February 2001.

From 1984 to 1993, he coached varsity basketball at De La Salle High School in Concord, California. The De La Salle basketball team under Nessman had a 155-40 record, one section and five conference championships, and four appearances in the NorCal tournament, including a runner-up finish in 1993. Jon Barry and Brent Barry, the sons of Rick Barry who would later play in the National Basketball Association, played at De La Salle under Nessman.

Nessman began coaching at the high school level after graduating from Berkeley: from 1981 to 1984, he coached cross country running and track and field at Salesian High School in Richmond, California.

Nessman was born in Stamford, Connecticut and moved to the Bay Area when he was nine. Nessman graduated from De La Salle High School in Concord, California in 1977. Nessman received his Bachelor of Arts degree in social welfare from the University of California, Berkeley in 1981 and later two master's degrees: from San Francisco State University (1988, education) and from Saint Mary's College of California (1995, physical education and recreation).
