He attended Bishop Luers High School in Fort Wayne, Indiana before committing to Northern Illinois University (NIU) where he played running back from 1999 to 2002. Hammock earned his bachelor's degree in marketing from NIU in 2002, and a master's in educational leadership from the University of Wisconsin–Madison in 2004. He and his wife, Cheynnitha, also a NIU alum, have a daughter, Tierra, and a son, Thomas Douglas.

Coaching career Thomas Hammock began his coaching career at the University of Wisconsin–Madison, serving as a graduate assistant for the Wisconsin Badgers from 2003 to 2004. The following season, he was named the running backs coach at NIU, reuniting with his former head coach, Joe Novak. In Hammock's first season as running backs coach, Garrett Wolfe rushed for 1,580 yards and 16 touchdowns in just nine games as NIU won the MAC West Division and appeared in the MAC Championship Game for the first time in school history. A trio that would run for 9,044 yards and 102 touchdowns during the three seasons Hammock was on staff. The most notable season being Montee Ball's 2011 campaign where he finished fourth in Heisman voting, breaking Barry Sanders’ single-season touchdown record with 39 total scores.

Hammock's success as a running backs coach at the collegiate level led to him joining the Baltimore Ravens in February 2014. There he served in a similar capacity under head coach John Harbaugh.

Northern Illinois On January 18, 2019, Hammock was named the 23rd head football coach at his alma mater, Northern Illinois University (NIU). In his first season back at NIU, his team finished the season 5–7 overall and 4–4 in Mid-American Conference (MAC) play to tie for third place in the MAC's West Division.

Hammock's second season as head coach was shorted due to the COVID-19 pandemic. Touting a roster that was composed of 71 percent freshmen, inexperience and youth became additional challenges for an already unprecedented season. The Huskies went winless in six games against conference opponents. However, the season laid a foundation for many freshmen who saw significant playing time.

Prior to the 2021 season, Northern Illinois was predicted to finish last in the MAC West Division. In week one, the Huskies went into Atlanta and stunned Georgia Tech, 22–21. The team that was led by transfer quarterback, Rocky Lombardi went on to win the conference that season and it earned coach Hammock the 2021 MAC Football Coach of the year.

On November 9, 2021, Hammock signed a contract extension through the 2026 season.

On September 7, 2024, Hammock's Huskies defeated the fifth-ranked Notre Dame Fighting Irish at Notre Dame Stadium, earning NIU its first-ever win over a top-10 opponent, and becoming the first MAC team to ever beat a top-5 opponent.

Seattle Seahawks On February 18, 2026, Hammock was hired by the Seattle Seahawks to serve as the team's running backs coach.
