Welcome to Mr. Gerrity's Class!

Hi everyone! My name is Mr. Gerrity and I will be teaching Geometry at the high school level this year along with the Graphic Design and Cybersecurity & AI technology courses. This will be my first year at MaST and I am very excited to be here! I graduated from Penn State in 2019 with an accounting degree and earned my MBA from West Chester in 2024.

A bit about me outside of school is that I am a huge Phillies fan (along with the other Philly teams and PSU Football) and an avid runner. I spend a lot of my free time following the Phils along with training for the upcoming Philadelphia Marathon in November. I am looking forward to a great year, and if you have any questions or concerns do not hesitate to reach out via email to wgerrity@mast3.org.
