Welcome to West Chester

Our people balance what’s important to the community and to the environment by transforming land responsibly, whether urban, greenfield, or brownfield, and integrating projects into the areas they serve.  We are truly invested in the natural world and are finding better ways to interact with it.

Whether cleaning up a contaminated site, upgrading water and wastewater treatment facilities, or creating an urban park, a commercial plaza, or a residential neighborhood, what we do each day makes a difference for people in Pennsylvania and our surrounding communities.
