Sarah Hamman

President and Restoration Committee


Sarah is the president of the Board of Directors for Olympia Ecosystems, and serves on the Restoration Committee.

Outside of her role with OlyEcosystems, Sarah is the Director of Science for Ecostudies Institute, a conservation non-profit based in Washington. Her work is aimed at researching and restoring rare species habitat in Pacific Northwest ecosystems using rigorous science and careful conservation planning. She is involved in all stages of the restoration process, with the goal of developing the most effective techniques to restore resilient and diverse above- and below-ground communities. Sarah holds a B.A. in Biology from Wittenberg University and a Ph.D. in Ecology from Colorado State University. Sarah is also an adjunct professor at The Evergreen State College, where she teaches in the Master of Environmental Studies program, and she serves as the Chair of the Research and Plant Inventory Committee for the Washington Native Plant Society.

Heather Grob

Treasurer and Finance Committee Chair


Heather is OlyEcosystems Treasurer and chair of the Finance Committee. As a labor economist with several years’ experience working in regulatory issues, Heather has worked with a variety of policy organizations, and has written and managed several research grants. She became even more interested in ecological issues through her study of occupational safety, health and stress where larger environmental concerns are vital to human well-being. Her position as Professor of Economics at Saint Martin’s University led her to develop courses in Cost-Benefit Analysis and Ecological Economics, popular additions for students in the Environmental Studies program and business programs. Heather is currently the Benefit Cost Lead for the Washington State Institute for Public Policy which performs non-partisan and nationally recognized analyses of public policy at the request of the State legislature. Heather received her PhD in economics from the University of Notre Dame in 1998.

Gabriel Taylor

Secretary and Restoration Committee Chair


Gabriel Taylor is Secretary for Olympia Ecosystems and a Licensed Engineering Geologist who specializes in natural hazard mitigation and earthwork construction. Gabe also is the Chair of our Restoration Committee where he is in charge of planning and coordinating the restoration actions, including regular volunteer work parties across our four preserves. Gabe holds a B.A. from the Evergreen State College and a B.S. from Western Washington University. His combined education in the humanities and earth sciences has instilled in him a sense of responsibility to participate in the mitigation or reversal of the environmental degradation he has witnessed over his lifetime.

Gabriel has been working at the Washington State Department of Transportation since 2005, primarily as a landslide and rockfall specialist. His professional background in applied science and engineering allows him to provide practical and technical assistance to OlyEcosystems in their efforts to restore and conserve local habitat and ecosystems. He is currently serving on the Board of Directors and is a member of the Restoration Committee and the Conservation Committee.

Gabriel is a musician, mountaineer, backpacker, bicyclist, and general outdoor enthusiast. He has a deep appreciation of the Pacific Northwest landscape and the wide array of habitat contained therein. He is also a husband and father. He is dedicated to doing his part to ensure that a livable world is passed on to the next generation, and share his appreciation of wilderness and nature with others. Through his efforts to conserve and restore West Bay Woods, Gabriel hopes to provide a wild and green space for Northwest neighborhood residents, or visitors, to find some quiet and solace. He works with OlyEcosystems with the hope that these efforts will provide a healthy forest for neighborhood children to explore, so they might nurture their own appreciation for nature, learn from the example provided by adults, and develop into responsible stewards of the environment.
