PPN Council
The PPN Council consists of the chairs of all 20 Professional Practice Networks (PPNs). The PPN Council meets quarterly via conference call and in person during the ASLA annual meeting to discuss matters of interest to all PPNs.
The Council Chair is a past chair from one of the PPNs. The Council Chair Designate and the Council's Immediate Past Chair also sit on the Council. In addition, the Vice President for Professional Practice is the Council's liaison to the ASLA Executive Committee.
