Mater Dei Catholic School in Lansdale will host a pep rally on Friday, Feb. 12 to show support for more than 50 faculty members, parents and students who will participate in Sea Isle City’s Annual Polar Bear Plunge the following day.

Diane McCaughan, principal of Mater Dei, will lead the group as they plunge into the frigid Atlantic Ocean.

The pep rally will feature the Mater Dei pep squad, cheerleaders, guest acts, polar bear mascots and many of the plungers who are raising funds for the tuition assistance program of the school.
