Theresa Pierno served as President and CEO of the National Parks Conservation Association from 2015 to 2026. She joined NPCA in 2004 after a distinguished career in public service and natural resource protection, and has helped to solidify the organization's role as the voice of America's national parks.
Prior to becoming President and CEO, Theresa served as NPCA’s Chief Operating Officer and played a critical role in the recruitment of talented, diverse and experienced staff, led the development of strategic priorities with a focus on water and land use policy, and helped to ensure the financial health of NPCA through revised management practices and successful fundraising efforts. Further, in an effort to engage and inspire new park stewards and advocates, she formed NPCA’s Next Generation Advisory Council—a group of young rangers, civil servants, public land advocates, educators, students and activists with a strong desire to lead national park advocacy efforts well into the future.
Theresa first joined NPCA in 2004 as Vice President of Regional Operations. In that role, she successfully doubled the field program to include more than 60 staff working in 24 offices across the country. The move further enhanced NPCA’s connection to national parks and their gateway communities and helped to solidify the organization’s role as the voice of America’s national parks.
Prior to joining NPCA, she served as a Vice President for the Chesapeake Bay Foundation (CBF) and Maryland Executive Director.
