Jon Houghton
Senior Principal Marine/Fisheries Biologist
Jon Houghton, PhD, has 35 years of consulting experience in the Pacific Northwest, the Rocky Mountains, and Alaska. This experience has met a wide range of client needs, including baseline studies, environmental impact assessment, natural resources injury assessment, ecological risk assessment, and mitigation and remediation planning. He is equally comfortable working in freshwater, marine, or estuarine environments. He has special expertise in the ecology of salmonids in the Pacific Northwest and Alaska, as well as in the effects of habitat alterations on coldwater fish populations and the effects of oil spills on the nearshore ecology of Washington and Alaska. Jon is very familiar with NEPA and SEPA regulations, and the Endangered Species Act and its implications for project permitting and operation.
Garry Horvitz
Senior Principal Geotechnical Engineer
Garry Horvitz, PE, LEG, has 34 years of geotechnical engineering experience, with a strong focus on waterfront projects such as the Pier D, Nimitz Class Carrier Pier at Naval Station Kitsap and the Terminal 18 Expansion at the Port of Seattle.

Bruce Rummel
Oceanographer/Biologist
Bruce Rummel is a biologist and oceanographer with 26 years of experience in water quality protection, including sediment management, habitat restoration, aquatic ecological risk assessment. He has led projects involving evaluation of dredging activities, discharge permit compliance, source control, and cleanup issues. He has conducted projects at Puget Sound Naval Shipyard, Naval Station Puget Sound, and Naval Station Everett in Washington; as well as Naval Air Station Adak in Alaska.
Jim Starkes
Fisheries Biologist
Jim Starkes has 23 years of experience. He has produced environmental assessments, environmental impact statements, and environmental baseline documents, and biological assessments in compliance with NEPA, SEPA, and the Endangered Species Act in Alaska and the Pacific Northwest. He has conducted numerous field investigations collecting fish, sediments, surface water, and benthic community samples in marine and stream environments. Jim's projects have included habitat mitigation and monitoring the success of habitat restoration projects.
Celina Abercrombie
Wetland Biologist
Celina Abercrombie has 10 years of experience for public and private entities. She has conducted wetland and stream delineations, critical areas project review, wetland and habitat restoration, marine and freshwater habitat evaluations and mapping, and GIS and GPS mapping. Much of her experience has been with wetland restoration, rare species surveys, and development of wetland mitigation banks as offsets for project impacts.
