"I am very excited to add Emily to our staff," Hamilton said. "She has been part of a strong Stetson program that has grown during her time there and allowed her to learn and develop as a coach under strong leadership. She brings a good balance to our staff on the field, as she will work with our attacking players.  Her ability to see the big picture of the game will allow our players to be able to learn from her on a daily basis. Emily will also be a great role model to our athletes and have an immediate impact on them as they prepare to be successful after their time as a student-athlete."
