Welcome to Lippincott Jacobs

Lippincott Jacobs is proud to be a part of Duffield’s growing team as we continue to enhance our community, knowledge, and client experience.

Today’s projects are complex and we are past the days where one person can do it all. Various specialties need to be utilized in order to get you across the finish line. Duffield is large enough to provide all of these diverse services, yet small enough to know each other personally which helps us to easily and routinely collaborate across our disciplines to resolve your engineering and science needs.

Enhancing our community one project at a time. Small enough to collaborate. Large enough to be technically diverse. Diverse thinking and collaboration leverage value.
