Marketing + Development Coordinator, Kellie Standish

Originally from the Seattle section of the PNW, Kellie grew up skiing the Washington Cascades and Mount Bachelor. She began as a volunteer while in college, and instantly fell in love with OAS, commuting from Salem quite literally every winter weekend. After graduating from Willamette University with a degree in political science and Spanish and a summer stint working in Costa Rica, she realized that her love for OAS was special enough to make Bend home. When she isn’t volunteering or working, she spends her free time skiing, biking, hiking and climbing. Access to the outdoors and the life that Bend provides for so many has been life changing for Kellie, and she hopes to use her work in OAS to ensure that everyone has access to not just outdoor experiences, but an outdoor oriented lifestyle.
