Brad Stevens is a professional basketball executive and coach. After high school, he attended DePaul University, where he played basketball and earned a degree in economics. He made the all-conference team multiple times and was a three-time Academic All-America nominee.

He transitioned into coaching after quitting his job at Eli Lilly and Company, joining the basketball program at Butler University as a volunteer prior to the 2000–01 season. He was promoted to a full-time assistant coach the following season. After five seasons in the role, he assumed the position of head coach on April 4, 2007, after Todd Lickliter left. In his first year, Stevens led Butler to 30 wins, becoming the third-youngest head coach in NCAA Division I history to have a 30-win season. In 2010, his third year as head coach, Stevens broke the NCAA record for most wins in a coach's first three years, exceeding the previous record by eight wins. In the NCAA Tournament, Stevens coached Butler to the first Final Four in school history, while also becoming the second-youngest head coach to make an NCAA National Championship game.

After Butler, Stevens led the Celtics to the NBA playoffs every year from 2014 to 2021, won a division championship, and appeared in the Eastern Conference Finals in 2017, 2018, and 2020. Stevens was named the president of basketball operations of the Celtics in 2021 following the retirement of Danny Ainge.
