Welcome, Corinne!

July 29, 2026

Dear 5th Square Advocacy Community,


We are thrilled to welcome Corinne Lagermasini as 5th Square Advocacy’s first Executive Director.


This marks an exciting new chapter as we grow from a lean, all-volunteer team into a staffed nonprofit, expanding capacity to advocate for abundant housing, reliable public transportation, and safer streets across Philadelphia. After years of building a powerful volunteer movement, hiring the first Executive Director is an important investment in 5th Square's future.


As a person who relies on walking, biking and public transit, Corinne is passionate about strong, vibrant, and healthy communities. Her commitment to creating places where people can thrive makes her a strong fit for 5th Square's mission. 


Corinne brings extensive nonprofit leadership experience to 5th Square Advocacy, having led community-based public health and human service organizations serving refugees, immigrants, and survivors of domestic violence. Throughout her career, she has helped mission-driven organizations navigate growth and change by building strong partnerships, developing collaborative teams, and bringing people together around a shared vision.


Please join us in welcoming Corinne as she helps us usher 5th Square Advocacy into this next phase of growth and impact.

Sincerely,


The Board of Directors
