Cheryl Lenell - Assistant Coach

Cheryl started playing volleyball as a freshman in high school. She played as a middle blocker all four years. She passed on the opportunity to play in college in order to go to a bigger college to focus on academics.  After marrying her husband Jack she played in adult leagues in her free time. After having children, her focus drifted from her work life to her kids. Now that they have grown up and have started playing volleyball as well, she is excited to start being involved in the sport she loves again.

Samantha Alexander - Assistant Girl's Coach

Coach Sammie started volleyball in middle school, she had been sure it was not her sport, but through Dr. Da Matta's coaching and belief in her, she went from barely making tryouts to playing Junior varsity as a sophomore in one season with him and his club.

Sammie's experience in club and volleyball in college has made her the athlete she is today by showing her how to work hard and to want to win for her team. She learned how to play safely and push limits. With a leap of faith, after her first year of college, she transferred to Iola, Kansas to finish her associates and play college volleyball. Having one of the best seasons of her volleyball career, she graduated in 2020 and returned home. Since her competitive years have stopped, she chose to take the opportunity to coach instead. Sammie's heart is to help girls find their way through volleyball and experience the lessons and memories they'll never forget.
