New Board members bring deep expertise in business strategy, law, and global and local relationship-building

PHOENIX (May 26, 2026) –Phoenix Art Museum announces the election of Dan Costello and Trevor Halpern to its Board of Trustees. Chaired by Andrew Cooper, Senior Vice President and Chief Financial Officer for Pinnacle West Capital Corporation and its primary subsidiary, Arizona Public Service Company (APS), the Museum’s Board of Trustees serves as fiduciaries and stewards of the largest visual-arts organization in the American Southwest. The new Trustees bring a range of leadership and professional expertise along with deep knowledge of the local community, strengths that will bolster the Board’s capacity to guide Museum growth across strategic priorities related to revenue and audience development. Serving a three-year team renewable up to three terms, the new Trustees will continue to empower the Museum, under the leadership of Jeremy Mikolajczak, the Sybil Harrington Director and CEO, to serve as a leading arts institution and arts-education resource for regional and national audiences.  

“We are honored to welcome Dan and Trevor to the Phoenix Art Museum Board of Trustees,” said Jeremy Mikolajczak, the Museum’s Sybil Harrington Director and CEO. “Their unique expertise and strengths in building innovative business models and partnerships will prove invaluable as the Museum seeks to advance its community impact, reach new audiences, and position itself as a cultural cornerstone of the Southwest.”

As Executive Vice President and Chief Business Officer, Costello oversees all revenue-generation departments, including Ticket Sales and Service and Global Partnership Solutions. Costello also oversees the organization’s strategies involving business intelligence, broadcast media, and the Phoenix Suns and Phoenix Mercury’s interest in the Legends Entertainment District. Under Costello’s leadership, the team has set franchise records for revenue and has been recognized by the NBA as a Changemaker, winning the league award twice for the creation of partnerships that shape an industry (PayPal in 2019, Footprint in 2022). Costello is a former Honorary Commander at Luke Air Force Base and currently serves on the Phoenix Suns/Phoenix Mercury Foundation Advisory Board of Directors.
