WNPA Leadership Team

Marie Buck
Marie Buck, CEO
Chief Executive Officer

Marie became WNPA’s CEO in July 2022. She is responsible for building on the organization’s strong foundation and reputation, expanding partnerships, diversifying the organization’s revenue, and enhancing the visitor experience in the 71 national parks that WNPA serves. She was most recently chief operating officer for the Grand Canyon Conservancy, where she successfully managed operations, organizational strategy, and systems, and also served on its board of directors. Prior to that, she was senior director of business operations at Phoenix Raceway (NASCAR), where she led a $180 million facility modernization that resulted in substantial increases in revenue and customer satisfaction. She holds a bachelor’s degree in accountancy from Arizona State University, is certified by the Maryland Board of Public Accountancy, and is a certified management accountant, finance manager, and SHRM professional. Marie loves the outdoors and the Grand Canyon, in particular, where she has taken 30 whitewater rafting trips down the Colorado River, and finds immense pleasure in sharing that passion with others as a guide. What she loves about her work is creating life-changing experiences for others, whether they are on a rafting trip, hiking, visiting a park, learning about indigenous people, or making a connection with the natural environment.
