Associated Earth Sciences, Inc. (AESI) is a multi-disciplinary, professional geotechnical engineering, hydrogeological, geological, and environmental consulting firm.
We were founded in 1981 by the late geologist Lou Lepp. Lou’s vision was to integrate or associate the sciences of geology, hydrogeology and the environment with the form and structure of geotechnical engineering. He felt that by understanding how the sciences of the earth and water were intertwined with the systematic problem solving approach of engineering, he could provide his clients with a more complete understanding of their project. We have expanded past the Kirkland corporate headquarters to open offices in Mt. Vernon and Tacoma. We feel that we have successfully integrated the science of the earth with the form of engineering. We have selectively added experience and expertise to our staff to further the integration of the earth science and engineering.
Our staff is our company. We are proud of who we are and what we have accomplished. We feel that success has a solid foundation in good communication, planning and staff training. Our services include a wide variety of project and client types. We are fortunate to have many return clients which we feel is a reflection of good engineering and good service. The relationships we have forged go beyond the project meeting table. Although we have a broad, well founded practice of geotechnical, hydrogeologic and environment consulting engineering, we are particularly strong in several specialized disciplines of site investigation, evaluation and design.
AESI’s current staff of 50 includes geotechnical engineers, geologists, engineering geologists, hydrogeologists, construction inspectors, and environmental specialists who are supported by a strong support team, complete technical and regulatory library and geotechnical laboratory.
