Where Innovation is Tradition

Within the space of a lifetime, the mid-Atlantic region — and the Washington Metropolitan Area in particular — has transformed itself. Since 1945, Walter L. Phillips, Inc. has been centrally involved in this transformation, helping a broad variety of projects come to fruition throughout the region.

We have a legacy of combining state-of-the-art engineering, creative problem-solving and outstanding customer service for our clients and their stakeholders. In an industry in which change and churn are the norms, we’ve worked hard to maintain a consistent, dedicated team focused on delivering the best engineering services and value available anywhere.
