The Geological Society of America is a mid-sized nonprofit based in Boulder, Colorado, that brings together geoscientists from academia, government, and industry to study Earth and related systems and to share scientific findings. Through meetings, publications, and professional programs, it supports research and helps members advance across career stages. The organization emphasizes cooperative research, public dialogue on earth issues, and the practical application of geoscience to societal needs. Its global community participates in activities that foster inclusion and science education. In January 2026, the society appointed Samuel Epstein as chief executive officer, signaling leadership change within the organization.
