Brennan Hagar was named an assistant coach on the Nebraska volleyball coaching staff in January of 2025. Hagar works with Nebraska’s middle blockers while assisting with other positions.
In Hagar's first year on staff in 2025, Nebraska finished the regular season unbeaten for the third time in school history (1994 and 2000) and won 33 matches in a row, the second-longest win streak in school history in the NCAA era. The Huskers completed their first unbeaten conference season since 2004 in the Big 12 to win a third straight Big Ten title. NU set a school record and led the nation with a .351 hitting percentage, while NU's defense was once again the best in the nation with a .129 opponent hitting percentage.
Nebraska's middle blockers excelled in a big way in 2025. Andi Jackson was the AVCA Middle Blocker of the Year and a first-team All-American, while Rebekah Allick was a second-team All-American. Jackson led the nation with a .467 hitting percentage and broke the Big Ten record with a .559 mark in conference play. Allick had a .450 hitting percentage, the No. 4 mark in the country and in school history.
Hagar spent three years as a graduate assistant for the Huskers from 2022-24. During that span, the Huskers went 92-11, won two Big Ten titles and reached the NCAA Championship match in 2023 and NCAA Semifinals in 2024. Hagar assisted with scouting reports and film review, as well as coaching the Huskers during beach volleyball season.
Prior to coming to Nebraska, Hagar played outside hitter at Ottawa University in Kansas. He was a two-time first-team All-GPAC selection. In 2021 he ranked 48th in the NAIA in kills per set (2.8) with 20 aces, 115 digs and 25 blocks. In 2022, Hagar averaged 2.5 kills per set with 14 aces, 125 digs and 45 blocks.
