The mood at Frankford High School is under the microscope, and it is not for a science project. The School District of Philadelphia has launched a formal climate audit at the Northeast Philadelphia campus after staff submitted written statements describing years of tension, intimidation and alleged misconduct. The timing is striking, coming just as students settled back into newly renovated classrooms following a long, bruising facilities fight that had already rattled the school community and raised concerns about leadership and culture.
According to The Philadelphia Inquirer, the district moved ahead with the review after receiving multiple staff accounts accusing the principal of creating a “toxic” atmosphere.

Damaged asbestos forced an extended closure in 2023, and the campus did not fully reopen until remediation was completed and nearly $30 million in repairs were finished in 2025. NBC10 reported that teachers returned to the site in August 2025, a long-awaited reopening that made questions about leadership and staff morale feel even more critical for families watching from the sidelines.
Union and district response
Philadelphia Federation of Teachers President Arthur Steinberg told The Philadelphia Inquirer that even if only a small portion of the allegations proves true, “that he’s not fit to run that school, or any school at all.” District spokesperson Monique Braxton told the outlet that officials “continue to engage with the Frankford High School community” and reiterated that the district does not comment on personnel matters…
