Amazing job ladies! You did it again. Huge team effort all around. That's a wrap for the Fall season. Back to work in January!

Great start ladies!

Great weekend at the PG Iowa Elite event in Indianola/Urbandale going 6-1 with a tough hard fought 1-0 semi-final loss to a talented Iowa Prospect squad. @JordynKennedy13, @GenevieveY27 @AliciaMarie5, @Tessamjones07, @_LaurenHagedorn, @SamanthaGripp, @MackSims_2

Proud of this bunch! 6-0 at the Top Gun IA College Prospect Series in Bettendorf, IA taking home the hardware!

Way to battle back in Iowa City with 3 straight W's! Congrats to the bomb squad 💣

This year my motto was “you’re not finished, even when you’re done.” I have been awarded Little Hawkeye Conference 1st Team, Southeast All-Districts, and now 1st team all-State. I am beyond thankful for the support I was given by friends, family, teammates, and coaching staff. ❤️
