PPN Council

The PPN council consists of the chairs of all PPNs. The PPN council meets quarterly via conference call 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.
