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!
