ABOUT AESI

In 1981, the local geologist Lou Lepp founded our company with an innovative vision. Lou aimed to blend the sciences of geology, hydrogeology, and the environment with the form and structure of geotechnical engineering. By recognizing the interconnectedness of these fields, he believed that he could provide his clients with a comprehensive understanding of their projects.

Today, we take great pride in carrying on Lou's legacy and fulfilling his vision through the expertise and enthusiasm of our experienced team. With a broad and deeply-rooted practice of geotechnical, geologic, hydrogeologic, and geophysics, we employ a specialized staff that brings expertise across numerous disciplines.

We believe that success is built on the foundation of teamwork, clear communication, and well-defined goals. Everyone on our staff plays an integral role in achieving our objectives, and we work collaboratively to ensure that we are all moving in the same direction. At the end of the day, our success is a testament to the power of teamwork, and we're proud to be a part of such a dedicated and talented group of professionals.
