Assistant Coach // 15 Elite

Katherine “Kat” Cooper is the Assistant Coach for the 15 Elite team. She currently plays Division I volleyball at the University of Tulsa after spending three seasons at San Diego State. Before her college career, Kat played for Ozark Juniors from 11s–18s and was a four-year letterwinner at Har-Ber High School in Springdale, AR.

This is Kat’s second year coaching with Ultimate Performance. Inspired by her own coaches—especially her current coach, Lauren Ramatowski—Kat is passionate about creating a supportive environment where athletes can grow in both skills and confidence. She emphasizes effort, communication, and resilience, and she loves watching athletes discover new strengths and push through challenges.

Kat brings a unique perspective as both an active player and coach, giving her athletes relatable insight into the game. She is excited to continue building relationships, fostering teamwork, and helping athletes reach their goals this season.
