Returning to Pacific County, she led field research on the ecological impacts of Spartina alterniflora, smooth cordgrass in tidelands of Willapa Bay for the US Fish and Wildlife Service, and mapped the presence of Viola adunca, early blue violets, host plant for Oregon Silverspot butterfly, Speyeria zerene hippolyta for Washington Department of Fisheries and Wildlife. She sampled phytoplankton in local waters for more than five years, monitoring species that produce biotoxins for several state agencies.

She was the Science Officer for ShoreBank Pacific, the nation's first environmental bank, and helped take the bank from less than $20M to more than $220M in assets. While at the bank she developed the bank's internal assessment tools, based on triple bottom line metrics, did the bank's carbon accounting metrics, and worked with clients to improve their energy and materials efficiency, and profitability.
