The son of a basketball coach, Johnson began coaching at the high school level, including at St. Bernard High School in Louisiana and Alief Elsik High School in the Houston area, while also working as a personal trainer and AAU coach for many future college basketball players.[2][1] In 2010, he'd be hired by Jimmy Tillette as an assistant coach at Samford where he'd stay until 2012 before returning to the Houston area and the AAU ranks.[2] Johnson would make his return to college coach when he joined Danny Kaspar's staff at Texas State in 2015 as an assistant coach.[3] In 2020 when Kaspar resigned after being accused of making racially insensitive remarks, Johnson was promoted to the head coaching position on an interim basis.[4]
After guiding the Bobcats to an 18–7 and a Sun Belt regular season title and earning conference Coach of the Year honors, Johnson was named the permanent head coach on March 11, 2021.[5]
