Jessica Siraco Steps Down After Transformative Tenure. Griffin brings national museum experience and a passion for mining history to lead MMGM’s next phase of growth.
BETHEL, MAINE — The Maine Mineral & Gem Museum (MMGM) has named Kristy Kay Griffin as Executive Director, ushering in a new phase for the acclaimed institution as it builds on five years of growth and discovery.
Griffin succeeds Jessica Siraco, who has served as Executive Director since 2022 and played a pivotal role in the museum’s advancement since joining in 2017. The leadership change comes as MMGM enters a new era, with continued expansion of collections, educational outreach, expanded lab research, and collaboration with other institutes, emerging as a rising force in Earth science education, research, and exploration in Maine and beyond.

Griffin brings over a decade of experience in museum leadership, curation, collections, exhibitions, and development. Her journey includes key roles at the Art Museum of the University of Memphis and, most recently, at the Institute of Museum and Library Services in Washington, D.C., where she supported institutions nationwide through grantmaking, outreach, and capacity-building. Griffin holds an MA in Anthropology from Colorado State University, where her research included the archaeology of mining sites and communities, and a BA in Communications, with a concentration in media studies, from Northern Illinois University.
“Getting an organization like MMGM off the ground takes tremendous passion and energy — and that work has been done beautifully,” said Kristy Kay Griffin, Executive Director. “With such a strong foundation and MMGM’s reputation as a world-class institution well established, we can now start thinking about long-term sustainable growth. The stars are the limit — pun very much intended!”
Griffin’s appointment follows an impactful tenure by Siraco, who strengthened the museum’s internal systems, expanded its community presence, and positioned MMGM for long-term success. She will continue to support the museum on a contract basis to ensure continuity in its advancement and development efforts.
“MMGM has been an incredible part of my professional journey,” said Jessica Siraco. “These last eight years have been transformative, and I’m deeply proud of what we’ve accomplished. I leave with full confidence in Kristy’s vision and passion for the museum’s mission. The museum is in great hands and I’ll continue to support its success however I can.”
Lawrence T.P. Stifler, Ph.D., Founder and President of MMGM, praised both leaders:
“Jessica’s dedication and professionalism helped elevate MMGM’s impact and solidify its foundation. With Kristy now at the helm, we look forward to an exciting new chapter of innovation, education, collaboration, and exploration. Her expertise in both museum leadership and the cultural history of mining communities brings a powerful and timely perspective to our work.”
The MMGM board, staff, and community offer a heartfelt thanks to Siraco and a warm welcome to Griffin as the museum continues its mission of bringing Maine’s geology — and humanity’s place in the universe — to light.
