STAMFORD —Stamford Museum & Nature Center CEO Melissa H. Mulrooney plans to retire after two decades, the museum announced today.
Effective March 31, Mulrooney of Stamford will end another chapter in her long executive career that included stints at the Delaware Art Museum and the International Tennis Hall of Fame Museum in Newport, Rhode Island. Her decision to retire comes soon after she opened the $16.5 million Planetarium and Astronomy Center at the museum in November. The 11,000-square-foot, 3 story building includes a 100-seat planetarium complete with a 40-foot dome and a top-floor, roll-back roof observatory, and classrooms for area students.
The Stamford Museum board has started a search for the organization’s next leader, partnering with the national search and recruitment firm Chaloner, which focuses on non-profit institutions.
Board President Douglas York made note of Mulrooney’s legacy at the Stamford Museum.
“Melissa has been the consummate professional working seamlessly with dedicated board leaders, highly accomplished staff, and visionary community leaders,” he said. “As a board, we celebrate and are grateful for her inspiring and enduring legacy for the beloved Stamford Museum & Nature Center.”
Mulrooney has been a dedicated champion in creating and achieving the museum’s 2010 Master Plan. This professional study, with architectural and design assistance from TSKP Studio of Hartford, has served as the visionary blueprint for the museum’s growth and success over the last 15 years.
Mulrooney believes this growth has stayed true to her vision.
“We want to be a safe haven where all who visit can immerse themselves in the educational magic of our site and enjoy each other,” she said.
The 2010 Master Plan has culminated in two major capital projects: the Knobloch Family Farmhouse opened in 2018, and the new Planetarium & Astronomy Center unveiled in November 2025.
Under Mulrooney’s leadership, the museum has evolved into a nationally respected, multidisciplinary institution rooted in environmental stewardship and experiential learning. Early in Mulrooney’s leadership, she led a strategic rebrand that established the organization’s distinctive visual identity, showcasing its recognizable cartouche bearing the four signatures of its mission: Agriculture, Nature, Art and Astronomy — a timeless framework that continues to define SM&NC today.
Known throughout the museum field as a pragmatic, visionary executive, Mulrooney guided the 118-acre museum campus through many challenges, including periods of economic challenge and the pandemic. Her goal was serve the community and provide facilities and programs that offer inspiration, education, recreation and joy.
During her tenure, annual participation doubled to more than 200,000 visitors, education programs expanded to serve 140 regional schools, and adult programming and events have more than quadrupled. She has strengthened its educational reach, expanded its museum exhibition profile, and fostered a high-performance staff culture grounded in mission clarity and community trust.
Mulrooney’s career spans decades of leadership in the museum and cultural sector, including executive roles at the Delaware Art Museum with two capital expansions, and renovating and redesigning the International Tennis Hall of Fame Museum in Newport. At the Stamford museum, her ability to blend brand development, strategic planning, government relations, and collaborative fundraising has positioned the institution for long-term success as it approaches its 90th anniversary in 2026.
Candidates interested in being considered for the position should contact search consultants Beth Kitzinger (beth@chaloner.com) and Jenn Saldarelli (jenn@chaloner.com). The Board, with Mulrooney’s input and assistance, will ensure a smooth and effective transition of leadership.
