Landis Evans + Partners is led by a team of hands-on experts. It’s important to understand that our company leadership are not merely figureheads. Instead, each is a skilled practitioner, directly involved in numerous projects every day. They serve as long-standing, reliable resources for clients, project managers, as well as mentors for our junior staff. Their own work varies widely because each of these individuals are uniquely qualified in multiple areas. Bruce Landis is a professional engineer and certified land use planner; Dallas Evans is not only a civil engineer but also a biologist; and Theo Petritsch serves as an Engineer of Record on transportation design projects, and leads federal multimodal transportation safety research. We call them experts because they are recognized by their professional peers, as well as public and private sector clients as top sources of insight in their fields. We encourage you to learn more about each of them and reach out if you have any questions pertaining to an ongoing or future project.
