Allison Weiss, Executive Director

Allison Weiss, Executive DirectorAllison Weiss has been the Executive Director of Sandy Spring Museum since May 2012, having worked in the field of museums since 1995. Incorporating a world view she acquired while serving as a Peace Corps Volunteer in West Africa and obtaining a master’s degree in cultural anthropology, she sees history museums through the lens of a community builder.  Instead of focusing on the traditional model of static exhibits and passive programming, she is dedicated to turning local history museums into centers of community engagement. Recognizing that the most valuable learning experience is one that allows for participation through a sense of personal ownership, she has paved the way for individuals and organizations to co-create with the museum.

Allison’s last position was as executive director of the Southern Oregon Historical Society, where she was largely credited with the successful turn-around of the Society after it lost its sole source of funding. During her tenure, her work was recognized by the TCC Group, who invited her to co-present a state-wide webinar on adaptive leadership.

“Sandy Spring Museum is community-activated. Nearly everything that goes on here is at the behest of the community. Is it too idealist to say that museums can help make the world a better place? I really believe that. That’s why I’m here.”
