Kristina Rylands, Yosemite Regional Director

Kristina was first inspired by Yosemite as a 10-year-old and knew from that first visit to Tuolumne Meadows that she would return, which she did as a high schooler in what was then known as Yosemite Institute. She remembered asking her educator, "How do you GET this job?" After a career as a public high school teacher, Kristina returned to Yosemite in the 90s to become a YI (now NatureBridge) educator, which eventually led to a 13-year career with YOSE NPS as a writer/editor, planner, and project manager. She has served as the Yosemite Regional Director for NatureBridge since 2011. Inspired by her experiences as a student, her passion for connecting young people to nature through NatureBridge programs comes from her own deep personal connection. As Yosemite Director she oversees an operation of 65 staff that inspire as many as 15,000 young people annually. Each year, NatureBridge in Yosemite contributes $7.5 million in educational programming on behalf of and in partnership with the National Park Service. In addition to supporting the board of directors, Kristina also manages the effort to build the National Environmental Science Center in Yosemite, a 224-bed net-zero energy LEED Platinum facility that will soon open its first phase to students. Kristina has a BA in English and environmental science from UCLA, a teaching credential from UC Berkeley, and an MA in Organizational Leadership and Ethics from Claremont Lincoln University. When not at work, she enjoys connecting to the outdoors by way of hiking, biking, horseback riding, skiing, art journaling, and lounging by rivers and streams with friends and family.
