Company Overview

Collaboration, science, and progress
Shannon & Wilson is an internationally recognized consulting firm dedicated to providing quality services in the fields of geotechnical engineering and the applied earth sciences. We commit ourselves to providing clients comprehensive information to guide them through decision-making processes and arrive at practical, cost-effective solutions for each project. We achieve this by maintaining a staff of talented engineers, geologists, and scientists.

Shannon & Wilson plays a key role in the design and construction of many challenging endeavors, both public and private. We work on projects that are award winning, technically complex, and involve major capital improvement costs, as well as smaller-scale projects with limited budgets. Regardless of size, we give each project the same attention to technical excellence, quality control, and responsiveness.

Committed to giving back
Shannon & Wilson participates in a variety of charitable and community involvement organizations through volunteer hours, donations and financial contributions.  We have touched the lives of thousands of men, women, children and pets through the caring and generous giving of our employees and their participation in charitable programs.

Opening doors for the future
Shannon & Wilson has funded several scholarships and fellowships at universities around the county.  The following were funded to promote the education of deserving students in engineering and earth sciences and to honor our founders and long-time employees who helped establish Shannon & Wilson's reputation for technical excellence.

Employee ownership — we are in it together
