Coaching Staff

Adam Rollman
Assistant Coach

Adam Rollman joined the MSU staff on a full-time basis in February 2018 after serving as a volunteer assistant in 2017. During his first season with the program, Rollman’s duties include utilizing DataVolley software, film and statistical break down for both Missouri State and opponents, maintaining team video equipment and coordinating match-day film setup, creating and aiding in MSU player and opponent scouting videos, and assisting with other day-to-day duties of the program.

Rollman has accumulated extensive coaching experience since graduating from the University of Nebraska in 2012, most recently serving as an assistant coach and recruiting coordinator at Central Michigan for the 2015 and 2016 seasons. He worked primarily with the Chippewas’ outside hitters and defensive specialists, helping the program to its highest conference win total in three years in 2015.

The Norfolk, Neb., native spent the 2014 season as an assistant coach at Jacksonville University, aiding the Dolphins to the Atlantic Sun Conference Tournament title and an NCAA Tournament appearance.

Rollman has also served as a volunteer assistant at Creighton, Iowa, and Nebraska Wesleyan, and was a student manager for the Nebraska volleyball team during his time as an undergrad.

He was a four-year starter as an outside and opposite hitter for the men’s club team at Nebraska, serving as the club president his senior year and helping the team to top-10 national finishes in each of his four seasons. His resume also includes numerous coaching stops with clubs and summer camps.

Stokes on Rollman:
“I had the opportunity to really get to know Adam Rollman over this past season as he volunteered his time to assist with our program. Not only was he a big part of our undefeated MVC season, this time also gave me an opportunity to witness his hard work and talents day in and day out. There was no doubt in my mind that if a position ever opened up in the future, Adam would be a great addition to our full-time staff. Our student-athletes could not be happier that Adam is becoming a full-time BEAR.”

Sara Thomas-Dietrich
Assistant Coach

Sara Thomas-Dietrich returned to her alma mater as an assistant coach in February 2018.

No stranger to coaching success, Thomas-Dietrich spent seven seasons from 2011-2017 as the head coach of her high school alma mater, Althoff Catholic High School in Belleville, Ill., culminating with an Illinois Class 3A state title and 41-1 record in 2017.

Thomas-Dietrich coached 10 players that went on to play college volleyball, five all-state selections, three conference players of the year, numerous all-conference selections, and twice earned coach of the year honors from the Belleville News-Democrat.

In addition to her coaching duties, Thomas-Dietrich worked in private business in the areas of sales and marketing, event coordination and customer experience.

During her playing career, the former Sara Thomas helped the Bears to three NCAA Tournaments, including a trip to the second round in 2006, and won Missouri Valley Conference Defensive Player of the year honors as a senior in 2007. Also a first-team all-MVC pick that season, she averaged 3.20 kills on .279 hitting, 3.45 digs and 1.23 blocks per set, finished her career with 797 kills, 1,117 digs, 316 blocks and 288 assists in 131 matches.

Thomas-Dietrich graduated from MSU with a Hospitality & Restaurant Administration degree in 2009. She and her husband Brad have two daughters, Emma and Charlotte.

Stokes on Thomas-Dietrich:
“I have kept my eye on Sara after she graduated as I knew she was going to develop into a great coach. After winning a state championship this past fall as well as playing for Missouri State when we went to the second round of the NCAA Tournament, Sara knows what it takes to win at a high level. She is one of the best six-rotation players I have ever coached. Being named Defensive Player of the Year in the Valley for being able to block and defend proves that. She can train any position on the floor and will make an immediate impact in the development of both our middles and right sides. Her enthusiasm for coaching and passion for the Bears will make an impression on everyone she meets.”
