Joining G&A well over 20 years ago, Trevor is an expert in his field and provides leadership and guidance to our Geotechnical department. Trevor’s work includes foundation and subsurface investigations, sinkhole/karst hazard studies, stormwater infiltration investigations, and retaining wall design. He has presented on geology and green stormwater infrastructure topics on behalf of professional organizations including the Philadelphia Engineer’s Club, the American Water Resources Association, and the Pennsylvania Ground Water Association.

In addition to the rewards of an elusive day in the field, Trevor finds multidisciplinary project collaborations to be an excellent way to engage his expertise while integrating the perspective and knowledge of others.
