PostbacCAS Advisory Board

As is the case with all Liaison-powered Centralized Application Services (CAS), an advisory board comprised of CAS users will determine ALL policies, procedures and working standards for PostbacCAS. Our dedicated and veteran PostbacCAS advisory board consists of these eight postbac program directors who facilitate these decisions. Liaison does not establish policy, but rather implements the decisions made by this group to best advance the service.
