Myanna Cook enters her fourth season coaching with the Sycamores in the 2024-25 season.

In her second year of coaching for ISU, Cook helped lead the Sycamores to a program-best second-place finish at the 2023 MVC Championships and challenged Missouri State until the final day of competition. The Sycamores set 13 new records over the course of the 2022-23 season with 15 different athletes earning 16 All-Conference nods at the championships.
