Tamsin Fleming
Operations Manager

Growing up in Portland, the forests and rivers surrounding the city were a defining aspect of Tamsin’s childhood and she has seen how important it is to actively conserve and restore these environments for future generations. Graduating with a degree in General Science and a double minor in biology and chemistry, she quickly focused on conservation biology after learning about the crisis facing Pacific Northwest salmon. Tamsin is excited to continue working to preserve waterways, recover native fish populations, and create sustainable infrastructure with the Steelheaders. In her free time, Tamsin is most likely to be found hiking, camping with friends, or cooking new recipes.

Leslie is responsible for doing the associations' bookkeeping, payroll, financial reporting, and permit applications.

Grace Petermen
Confluence AmeriCorps member

Born in England and raised between Florida and Chicago, Grace found stability and comfort in non-human creatures while growing up. After several years working at a domestic animal non-profit in Los Angeles, she became interested in how humans relate to the natural world more broadly. She sees nature, like art, as a unifying force that transcends language with the power to heal and unite. Grace holds a bachelor’s degree in studio art from Wheaton College and a graduate certificate in Wildlife Management from Oregon State University. She speaks Russian and enjoys yoga, drawing, and singing. Grace looks forward to fostering community engagement in wildlife conservation through the Oregon Department of Fish and Wildlife's Fish Eggs to Fry, Hooked on Family Fishing Day, and Garden for Wildlife initiative. She will also support NWF's Eco-Schools USA and Schoolyard Habitats during her service term.
