Environmental Science Associates Adds Paul Schlenger and Abby Hook to Biological Resources and Land Management Group in Seattle


Environmental Science Associates (ESA), a leading environmental science and planning firm with offices on the West and Gulf Coasts, welcomes Paul Schlenger as principal associate and Abby Hook as senior managing associate to its Seattle office in the Biological Resources and Land Management Group. With nearly four decades of combined experience in ecosystem recovery and habitat restoration planning and design, both Schlenger and Hook join ESA after owning their own environmental consulting companies.

“We have known both Paul and Abby for years and have long admired the innovation, passion, and professionalism they each bring to their work,” said Margaret Clancy, ESA vice president and northwest regional director. “They are truly thought-leaders on key issues affecting our region including climate reliance, restoration, salmon recovery, and strategic planning; and bolster our ability to tackle challenging environmental problems in a strategic, scientific, and collaborative way.”

With more than 22 years of experience, Schlenger is a fisheries and restoration ecologist, specializing in salmon biology, aquatic ecology, habitat assessment, and restoration planning and design. He has extensive experience working in marine nearshore and estuarine environments, as well as in large and small rivers and lakes. Schlenger has served as a project manager on small scale to multimillion dollar efforts for clients including the Washington Department of Fish and Wildlife (WDFW) and U.S. Army Corps of Engineers. He has a strong background in ecological assessment, and much of his work has focused on characterizing fish and other aquatic resource distributions in relation to habitat conditions and manmade modifications. Paul applies this knowledge to mitigation, restoration, and protection planning at site, watershed, and regional scales, as well as habitat restoration design. He is a Certified Fisheries Professional through the American Fisheries Society. Schlenger earned his M.S. in Fisheries from the University of Washington and his B.A. in Environmental Sciences from the University of Virginia.

A hydrologist and conservation planner, Hook boasts more than 17 years of experience providing leadership for complex planning and ecosystem recovery projects. Her work has focused specifically on the Puget Sound watersheds, where she guides multi-jurisdictional collaboration engaging local and tribal governments, utilities, and non-profits to reach both watershed and regional goals. Particularly versed in salmon recovery planning throughout the Pacific Northwest, Hook has worked on several projects for the Puget Sound Partnership and has regularly facilitated the Salmon Recovery Council. She also supports the Governor’s Task Force for the Conservation of Southern Resident Killer Whales, addressing orca recovery through the development of actions across Chinook harvest, habitat, hatchery, hydropower operations and predation across WA state. Hook is part of the Conservation Coaches Network and received her M.P.A., M.S. in Hydrology and B.S. in Forest Engineering from the University of Washington.
