Principal’s Bio:

Upon earning a Bachelor’s Degree in The Art and Science of Teaching from Temple University in 1997, Thomas Mullin started his professional career with the School District of Philadelphia at Thomas Fitzsimons Middle School. Three years later, he transferred to the Hon. Munoz-Marin Elementary School in West Kensington to teach literacy and mathematics to students in grade 8. He was also part of a team that opened the new Julia DeBurgos Elementary School at 4th and Lehigh Avenues in West Kensington in 2003.  During his six years there, he served on the school leadership team as well as taught science to students in grades 5 through 8 while completing his Master’s Degree in Educational Administration.

He was Assistant Principal of John B. Stetson Middle School when it was turned over to ASPIRA of PA and was part of the team that significantly improved the school climate and the academic programs available to students. Some highlights include removing Stetson from the State of Pennsylvania’s persistently dangerous list, increasing student attendance to above 90%, and significantly increasing academic achievement in both math and reading.

In July of 2015, he was selected to serve as the Principal of John B. Stetson Charter School. If you would like to contact me, my email address is tmullin@stetson.aspirapa.org. You can also reach me by phone at (215)-291-4720.


Assistant Principal’s Bio (Letter from Glenda Marrero):

My name is Glenda Marrero, and I am the proud Assistant Principal of John B. Stetson Charter School.

I graduated with a Bachelor of Arts in Education from LaSalle University with a dual Certification in K-6th Education and Special Education.  Most recently, I received a Master’s Degree in K-12th Education Administration from Gwynedd-Mercy University.

Upon graduating from LaSalle University, I started my professional career in the city of Camden New Jersey, where I taught students in Kindergarten and tutored 6th-8th math.  After three years at Camden, I transferred to Antonia Pantoja Charter School in Philadelphia, where I taught students in grades 4th and 5th literacy and mathematics.

In 2011, I was selected to serve in ASPIRA’s Instructional Leader Apprentice program.  Two years into this position, I was given the opportunity to serve as the curriculum coordinator where I was part of a team that worked in the K-12th ASPIRA’s District Curriculum. In August of 2014, I served as the Lead District Instructional coach and Curriculum Supervisor for K-12th Schools in Camden, New Jersey. 

In July of 2015, I was selected to serve as the Assistant Principal of John B. Stetson Charter School.

Outside of school, I enjoy spending time with my husband, two children and my two dogs.  My interests include gardening and restoring my 180-year-old Victorian house.

As the Assistant Principal of John B. Stetson Charter School, I encourage you to contact me anytime with ideas, questions, or concerns.  Your thoughts and inputs are always valued!   Together with parent partnerships we will continue to make John B. Stetson an outstanding school and a great place for all kids to learn!
