PPN Leadership

ASLA members who want to be involved in guiding the direction of their Professional Practice Network (PPN) and share their expertise with a national audience may volunteer to join their PPN leadership team.

Any member of a PPN may volunteer to join their PPN’s leadership team. Most leadership teams meet once a month via Zoom during regular working hours. Come nerd out with like-minded professionals about your practice area niche!
