GSA's Commitment to Diversity

The Geological Society of America (GSA) affirms its belief and commitment to diversity and will continue to develop its diverse base. GSA is dedicated to maintaining an organizational climate where differing ideas, abilities, backgrounds, and needs are fostered with opportunities for members from divergent experiences to participate and contribute. GSA recognizes that diverse perspectives are important and necessary for responsible and representative decision making and leadership.
