Hello. My name is Mr. Gillis and I am the mathematics teacher on the Excel team. This is my fifteenth year teaching seventh grade here at the Dallastown Middle School.

We have twin siblings one boy and one girl who turned seven years old this past spring. When I’m not teaching in the classroom there are several interests I enjoy being a part of. You could find me, playing ping pong or cheering for the Philadelphia Eagles or completing some kind of exercise work-out like running, lifting, etc. I am looking forward to great school year together.
