Seth Zuckerman

Executive Director

His roots are in northern California, where he directed the Wild and Working Lands program for the Mattole Restoration Council, collaborating with private landowners in realms that included light-touch timber harvest, fire hazard reduction, and invasive species control. He came to the Northwest in 2013 in search of steadier precipitation. He holds an A.B. in Energy Studies from Stanford University and an M.S. in Energy and Resources from the University of California at Berkeley. Seth’s favorite thing to do in the forest is to forage for delectable mushrooms.

Rowan Braybrook

Director of Programs
Rowan grew up in the beautiful San Juan Islands in Washington State. After college she served in the Peace Corps in northern Madagascar, working in the Makirovana forest complex and surrounding communities on sustainable agriculture and environmental education. She then relocated to Washington, DC to work with Conservation International on field program management and environmental policy, gaining considerable expertise in UN acronyms in the process. Rowan holds a B.A. in Sociology and Anthropology from Middlebury College and an M.A. in Public Management with a concentration in environmental policy from Johns Hopkins University. Her favorite thing to do in the woods is to find the perfect spot for a mid-hike picnic.

Kirk Hanson

Director of Forestry

Kirk is a small woodland owner with over 200 acres of family-owned forestland in western Washington. He’s worked on behalf of small woodland owners for more than 25 years, bringing a passion for ecological forestry and simplified hands-on management practices that allows forest owners to take a direct role in the stewardship of their own land. As a member of a three-generation family-owned forest, Kirk understands the issues and opportunities facing small woodland owners and relishes developing new strategies for optimizing the economic and ecological potential of their forests. Kirk worked for six years with the Washington DNR’s Small Forest Landowner Office before joining NNRG in 2006. He also teaches ecological forestry as an adjunct instructor at the Evergreen State College. Kirk’s favorite way to spend time in his forest is felling trees and pruning.

Jaal Mann

Lead Forester

Jaal’s passion for forests began in the cloud forest of Costa Rica, and eventually turned into a Master of Environmental Studies degree from The Evergreen State College. He began his forestry career surveying streams for large landowners and then transitioned to managing O’Neill Pine Company’s 2,200+ acres of FSC-certified timberland. At NNRG, Jaal enjoys the opportunity to use the landowner’s perspective he gained in his work at O’Neill Pine Company to help other small landowners across the region. Jaal’s favorite thing to do in the woods is backpacking in old growth forests and alpine meadows.

Karen Gray

Finance Director

Karen brings over thirty years of accounting and finance experience to NNRG. She has an MBA in finance from University of Puget Sound, and she loves helping NNRG achieve its mission of caring for forests and working with landowners to manage their lands in ways that contribute to rural economies.

Rick is also a Certified Wetland Specialist and a Certified Forester (#71). Rick’s favorite thing to do in the woods is help landowners realize their forest visions.

Sam Castro


Sam fell in love with forests growing up in the Sierra Nevada mountains. As an undergraduate he studied ecology while assisting with research ranging from forest ecology to small mammal behavior. He decided to pursue a career in sustainable land management and earned a Masters of Forest Resources from the University of Washington. Sam has since worked with the King County DNR and the US Forest Service to manage public forest lands and is excited to promote and implement ecological forest management with the NNRG. His favorite thing to do in the forest is mountain biking and volunteer trail maintenance.

Alexandra Dolk

Alex grew up amidst the coastal forests of Whatcom County. Prior to joining NNRG in 2018, Alex worked in communications for an outdoor adventure company, then spent several months engaged in bat research in rural Malawi. While working as Outreach Coordinator for NNRG, Alex completed masters degrees in public policy and forest sciences at the University of Washington. Alex’s favorite thing to do in the woods is to watch bats catching insects at dusk. 

Nora Halbert

Forestry Technician

Nora is back home in the South Puget Sound after a decade sampling land management, ecology and geophysics research across the Southwest and Great Plains states. After college she worked as non-partisan Legislative staff for the 2019 and 2020 Sessions. She loves building relationships and learning the process of merging good data, practical economics and adaptive policy with small land owners. Her favorite things to do in the woods are enjoying little moments of silence, disconnecting, and finding super cute bugs.

Seeking a more temperate climate, Gustavo relocated to Grays Harbor County in 2017 and began his forestry studies at Grays Harbor College.
