Associate Directors

The Board is elected by the Associate Directors (ADs), a large and diverse group of volunteers who represent the various communities that comprise the organization. The ADs advise the board on issues of importance to the membership-at-large.

Membership in the ADs is open to all regular members who have volunteered on any CASSS committee and who actively participate in AD activities. CASSS is unique in the fact that membership is complimentary. Your participation is your currency. CASSS' ADs are a diverse group of members who contribute their time and expertise. Together, our volunteers advance the CASSS community in the direction of dignity, respect, scientific truth, and the betterment of humanity.
