Leadership in art museums is a changing construct: historically, these institutions were established as hierarchical, top-down structures that prioritized sole expertise to dictate success. Today, museums are searching for ways to become more responsive, collaborative, and multivocal institutions that value community voices and expertise. A growing variety of museum professionals ask how to better reflect and integrate local communities within their museums. We share reflections, insights, and lessons learned from a multi-year case study at the Tucson Museum of Art and Historic Block (TMA), which focuses on redefining curatorial leadership as community-based and collaborative to expand approaches to exhibition development and interpretation. The authors of this article highlight how network governance/collaborative leadership can be applied to curatorial practice to develop exhibitions rooted in collaborative stewardship, multivocality, and community-based approaches. Here, leadership is defined as a way in which a museum influences its communities and vice versa. In addition, we discuss strategies for building multi-directional and collaborative initiatives to shape a more equitable and inclusive museum.
