Quotation Mark

"The team of district staff and outside contractors who designed and built the project centered the priorities of students when making decisions on how the new gym would look. It was really important to that team to take the student voice and bring it to life with this project. It truly is an innovative space that has students’ learning, growth and well-being in mind in every corner of this space."
