Dear Mastbaum Families,
Welcome to the 2025-26 school year! We are excited to build upon our recent successes, where we have established significant growth in building safety and student achievement, as well as a fun and energetic learning environment that celebrates students with numerous events, activities, and partnerships.
At Mastbaum, our school vision is “We build the future.” As our students work to build the future for themselves and their communities, we work with you, the families, to be builders as well.
We all engage in the work of “building” in three different ways. First, Mastbaum students are members of a safe and welcoming school community where their leadership is encouraged and nurtured. Second, they receive rigorous academic programming in English, History, Math, Science, and electives courses. Finally– and this is what makes Mastbaum unique– they engage in a field of intensive Career and Technical Education study: Automotive Technology, Carpentry, Culinary Arts, Electrical Technology, Film and Video, Graphic Design, Health-Related Technology, Plumbing Technology, Police Science, Sports Marketing, and Welding Technology. In addition, we partner on-site with 12plus and Philadelphia Academies, Inc to help students realize their postsecondary goals.
This is the experience that sets us apart! With the broad range of specialized skills that a student earns at Mastbaum, they have the ability to:
- Enroll in college
- Enroll in an advanced trade program
- Directly enter a skilled career field
- Work w/industry partners like the Navy Shipyard, SEPTA, PECO, PGW, Philadelphia Airport, Elliot Lewis, etc.
This is my seventh year as principal of Mastbaum, and I am looking forward to another great year in serving our school community.
Sincerely,
David Lon, Principal
