Deb Fassnacht (she/her)

Executive Director

Deb camped, fished, and played with her big family along the Sun River while growing up in Great Falls, Montana. She has been gravitating to water and nature ever since. Deb holds a Master's in Education, Bachelor’s in Forestry, Natural Resource Conservation, and her Secondary Science teaching certification from the University of Montana. Deb is one of the founders of the organization, along with Wendy Berthold  and Eric Ringelberg. What began as a volunteer stream monitoring effort in 1996 based in Deb’s home, has grown into a successful non-profit organization focusing on watersheds, groundwater, and wetlands education. Deb brings science teaching and education/outreach experience to WEN from previous agency and nonprofit work. When not at the river or neighborhood creek, Deb enjoys hiking, skiing, and sailing on Flathead Lake with her husband, Henry, family, and friends.


Sara McComas

Grants & Programs Administrator

After completing her B.S. in biology in Tacoma, WA, Sara moved to Seattle where she met her husband, Josh- a recent transplant from Montana. Five years later they relocated to Missoula, where she completed her second degree in Resource Conservation at UM and completed a grant writing internship at WEN. A job opportunity for her husband returned them to Washington, but another five years later they were back in beautiful Missoula. Sara has enjoyed working with several conservation- and education-minded non-profits during her two tours in Missoula- including Montana Water Trust, Montana Trout Unlimited, National Wildlife Federation and, or course, WEN.
Sara now works at WEN part-time, immersing herself in grant administration, bookkeeping, and general program administration. When not in the office, Sara tries to keep up with her 8-year-old son, adopted animals (one tenacious terrier, one fat tabby, and one curious calico), three chickens, and never-ending home remodeling projects. In her rare spare moments, she can be found in the garden or reading.

Brook Bauer (she/her)

Communications Coordinator 

Brook found herself in Missoula after completing her undergraduate degree in Earth Science and Communication Design at Quest University, Canada. Having grown up in Portland, Oregon, with its close proximity to Mount Hood and the Pacific Ocean, has given her the privilege to spend a decent amount of her time enjoying the local hydrology and geology. Whether it's on top of mountains or in the ocean, she loves to see the hydrologic cycle do its magic! With a drive to learn more about the hydrogeology in Missoula, Brook is currently working with WEN as a communication coordinator to help make sure all of the fabulous knowledge about the creek makes it to our community.  

Taylor Tewksbury (she/her)

UM Intern 

Originally from upstate New York, Taylor earned her B.S. in Marine Biology from the University of Delaware and is currently pursuing an M.S. in Environmental Studies at the University of Montana.

However, she fell in love with Montana's landscape while leading citizen science fieldwork in Yellowstone and completing trail work with Montana Conservation Corps. She is passionate about environmental education's capacity to build relationships between people and place. In her free time, Taylor enjoys painting, climbing, birding, cross-country skiing, and hiking with her pup, Willa. Taylor is a certified Wilderness First Responder.
