Caitlin Costello has focused her academic and professional accomplishments on the realms of accessibility, sustainability, and environmentalism. She is a graduate of Portland State University in Environmental Science and Anthropology. Her research and professional interests include the global health impacts of climate change as they relate to the accessibility of natural settings and culturally appropriate foods. Finding ways of making climate science tangible and relatable is of the utmost importance to her. Recently, she was the Partnerships and Programs Coordinator for PSU’s Student Sustainability Center and was able to develop and implement several professional programs with a focus on DEI practices and social justice activism. It is her belief that any community work is sustainability work. In her free time, she enjoys archery, historical costuming, and is a voracious reader.
Growing up in southern Ohio, Glenn and his brother spent long days exploring the creek near their family's home, following it to the Little Miami River near the confluence of the Ohio River. Glenn's love of the outdoors eventually led him to Colorado, where he spent a number of years leading community-based and international immersion programs at the University of Denver before serving as Executive Director of Bluff Lake Nature Center, an urban wildlife refuge and education center in Denver.
Glenn has a passion for advancing opportunities for underserved communities, work that has been at the core of his career. In his free time, he spends considerable time with his partner and family exploring the Northwest by bike, foot, and paddle. A passionate music fan, Glenn volunteers with the Pickathon Music Festival and consistently seeks out new artists. Glenn lives with his family in Northeast Portland.
Mark grew up paddling Minnesota’s 10,000 lakes and rivers and since then has been a teacher, naturalist, guide, program developer, trainer, and facility manager in western New York, Montana, and Oregon. Prior to joining the Tualatin Riverkeepers staff he coordinated Portland Audubon's annual Birdathon fundraising campaign, guided hiking and paddling trips for NW Discoveries, and developed programming for Road Scholar throughout the western US.
Mark volunteers as a board member of the North Clackamas Urban Watershed Council and Portland Nordic Club. His other interests include nordic skiing, traditional archery, and paleo-archaeology.
Growing up exploring the outdoors in Portland, Eve's passion for the environment led her to Lewis & Clark Law School, where she received her J.D. in 2024, with a Certificate in Environmental and Natural Resources Law. During law school, Eve spent summers interning for various public interest environmental law organizations, including the Center for Biological Diversity, the Sierra Club, and the Northwest Environmental Defense Center. Through these opportunities, Eve gained valuable experience working with the Clean Water Act and the Endangered Species Act. Eve will transition to the role of staff attorney upon bar passage.
In her free time, Eve spends as much time outside as she possibly can (rain or shine), whether that is biking around Portland, skiing at Mt. Hood, or hiking and camping in central Oregon. Eve also enjoys playing guitar, singing, and watching live music.
Jessica is a second-generation Oregonian who grew up camping mostly on Mt. Hood. She’s fished a few times, a crabbed a few times, caught a lot of frogs... and somewhere along the line, it shaped her soul.
Following a BS in education from Western Oregon University, and long career in the field, Jessica is now a homeschooling mom of 2 young children who also have a deep love of the outdoors. As a co-admin at Wild Recess, a local nature-based adventure and education co-op, she has the opportunity to instill an appreciation for the outdoors in people of all ages.
Volunteerism has driven her all over this world, from supporting the nurses in a failure to thrive clinic in Romania through Global Volunteers to helping rebuild the brackish coastline of the Louisiana bayou with In Good Company and, of course, our own "backyard" here in the PNW. Before joining the team, Jessica was a volunteer with our Stewardship program, where she helped maintain Dirksen Nature Park’s oak savanna habitat. You’ll often find Jessica, her husband, and two children camping, backpacking, bicycling, or kayaking all across Oregon and Washington. Her favorite place to kayak on the Tualatin River is simply upstream of the 99W launch and she can’t wait to share this excitement with the Riverkeepers community!
