Ben McCollum has added a fourth assistant to his first Iowa basketball coaching staff.

McCollum is adding former Texas Tech assistant coach Luke Barnwell to his staff at Iowa. Barnwell spent each of the past two seasons with the Red Raiders where he helped lead Texas Tech to consecutive NCAA Tournaments, including a trip to this year’s Elite Eight.

Along the way, Texas Tech ended Drake and McCollum’s NCAA Tournament run with a 77-64 victory in the round of 32.

“I have known Luke for a number of years,” McCollum said of Barnwell. “He is an elite recruiter, excellent coach and has had a ton of success at the prep level. He also has a lot of experience at the Power 5 level with one of the top coaches in the country in Grant McCasland. We’re excited to have Luke join our program.”

Prior to arriving in Lubbock, Texas, Barnwell spent 10 seasons as head coach at Sunrise Christian Academy in Wichita, Kan. During his stint at Sunrise, Barnwell was recognized as the 2021 and 2022 Naismith High School Boys Coach of the Year and led the team to the 2022 National Interscholastic Basketball Conference Championships.

“I am incredibly blessed to be a part of the University of Iowa and coach McCollum’s staff. My family and I look forward to being back in the Midwest to work for this university, community and program,” Barnwell said of joining Iowa.

Barnwell helped with the development of Big 12 Player of the Year and second-team All-American JT Toppin. The forward averaged 18.2 points and 9.4 rebounds per game this past season.

Texas Tech forward Darrion Williams earned All-Big 12 first team honors and Red Raider guard Chance McMillian garnered All-Big 12 second-team recognition under Barnwell’s direction.

Barnwell also coached NBA players Kennedy Chandler, Kendall Brown, Gradey Dick and Ochai Agbaji and helped train Buddy Hield and Ron Baker.

A native of Emporia, Kan., Barnwell played college basketball at Newman University and Emporia State before beginning his coaching career as a student assistant.
