New Faculty 2021-22

Dear Prairie Families,

I am extremely excited about this new group of employees coming to Prairie in the fall of 2021. From seasoned educators to those just starting their careers, we are fortunate to be welcoming this warm and charismatic group of people into our community.

Some are familiar to many of us and I believe all of them will have a positive impact on our community. Please join me in welcoming these outstanding professionals to our community.
