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!

Log in to asla.org to check which PPN(s) you’re in, under the Activities/Orders tab, if you're not sure of your PPN membership status.
