Bryan Petersen was announced as head coach of the South Dakota State men's basketball program in March of 2025. He was promoted to the head coach position after serving as an assistant for the Jackrabbits the previous six seasons.
Petersen enters his second year guiding the program heading into the 2026-27 season. He's the 23rd head coach of the program that began in 1903.
The Jackrabbits continued a long run of success when Petersen initially joined the program as an assistant in 2019. In his six seasons as an assistant for the Yellow and Blue, the Jackrabbits accumulated a 129-60 record featuring four Summit League regular season titles, two conference tournament championships and two NCAA Tournament appearances. He was at the forefront of SDSU's defensive game plans during his tenure which saw the Jackrabbits routinely lead The Summit League in opponent field goal percentage and scoring defense.
The Jackrabbit guards were Petersen’s positional focus during his time on Eric Henderson's staff. The group saw multiple award winners over a six-year stretch. Zeke Mayo (2024) and Baylor Scheierman (2022) garnered The Summit League Player of the Year award in their respective junior seasons, while Charlie Easley (2024) and Matt Mims (2023) were chosen as Summit League All-Defensive Team selections.
Petersen's stretch in Brookings have seen multiple Bobcats move on to professional careers. Scheierman was a First Round NBA Draft pick by the Boston Celtics in 2024. Mayo, along with former Jackrabbits in William Kyle III and Oscar Cluff, have spent times with NBA teams' G-League affiliates. Other Jacks that have played overseas after their time during Petersen's tenure include Douglas Wilson, Matt Dentlinger, Luke Appel, Easley and Mims.
Prior to his arrival at South Dakota State, Petersen spent six seasons as head coach of the Kirkwood Community College men's basketball program. He led the program to the 2016 and 2019 NJCAA Division II Championships while compiling a 157-38 overall record. He earned regional and national coach of the year honors in both national championship seasons. He coached four NJCAA All-Americans and saw a future Jackrabbit in Wilson, who eventually went on to become the 2020 Summit League Player of the Year and earn three All-Summit League nods, named NJCAA Division II National Player of the Year in 2018-19.
Petersen spent a season as an assistant at Kirkwood following three years as a graduate assistant at Iowa State. He worked as a Cyclone for one season for Greg McDermott (2009-10) and two seasons for Fred Hoiberg (2010-12).
His time on the Iowa State staff came after completing his collegiate playing career for the Cyclones. Over the course of his junior and senior seasons, Petersen sank 97 career 3-pointers and started 64 consecutive games for Iowa State. His first two years of college eligibility he utilized at Kirkwood. He was named a First Team All-American in his final season at Kirkwood, taking home Region XI Player of the Year honors. Petersen was also the first coach in the history of the NJCAA DII National Tournament to participate in a National Championship game as a player and win the National Championship as a coach.
Petersen graduated from Iowa State with a degree in Kinesiology in 2009 and earned his master's degree in higher education-educational leadership from Iowa State in 2012.
