Patrick Engineering is a national engineering & design, construction, management services, and technology firm. Since 1979, we have been providing services to local, state, and federal government agencies; private and public utilities; and FORTUNE 500 companies. Having worked in all 50 states and proven ourselves as a trusted partner, clients turn to us for the entire process of project delivery - from planning through construction to operation and maintenance. Patrick accomplishes this with a full suite of engineering disciplines, experienced construction managers, program management and project controls experts, and GIS and asset management technology specialists. We serve clients in the rail/transit, highway, aviation, manufacturing, utility, renewable energy, education, and health care markets. We take pride knowing the projects we work on have a positive effect on the community, society, and the environment.
Patrick Engineering Inc. was founded in 1979 by Daniel Patrick Dietzler, a 1971 civil engineer graduate of the University of Illinois. Dietzler began his career working primarily on the design and construction of hydroelectric and environmental projects for Harza Engineering Company under the guidance of world-renowned engineers.
Patrick grew from one engineer into a design firm preparing plans and studies for water resources projects and general civil engineering projects. Gradually, the firm became recognized as a railroad, track, and highway design firm and has continued to do work for those transportation clients. In 1999, the company began doing work for electric utilities designing distribution systems, substations, and transmission lines. That same year, Patrick expanded into geospatial services for a variety of clients.
Patrick grew to 500 employees in 2011, at which time SAIC (now Leidos) acquired Patrick Energy Services, a spinoff of Patrick. Patrick continued to provide electrical engineering services for heavy industrial users and that work continues today. Patrick has also provided our management services expertise to utilities for assistance with smart grid and renewables.
The company has grown over the years to provide infrastructure and technology services to industrial, governmental, and utility clients across the US and in select foreign countries. The company has been ranked among the ENR top 500 every year since 1992. Dietzler is the CEO and remains active in the business.

We are not an ordinary company.
Our work lives are steeped in tradition: We are engineers. Designers. Managers of service and providers of excellence. Contractors and design builders and technology experts. We are masters of budgets and schedules and time. Our souls are driven by a deep sense of personal and professional integrity. Honesty and respect are in our blood. We understand the value of a dollar earned and the impact of a dollar spent.
And we are so much more. We are moms and dads, sons and daughters. Brothers and sisters and friends and neighbors. We are caregivers, scuba divers, animal lovers, and shoulders to cry on. We coach and run, we teach and learn, and we volunteer. On occasion, we are super heroes. Our work family includes veterans and active service members, first responders and campaigners for causes. Gratitude runs deep and we give back as hard as we receive. We are driven, we are focused, and we are insanely motivated. We are you.
We work hard, we play hard, and we wouldn’t have it any other way. Safety is ingrained in our lives and we are passionately committed to results. We believe that what we are doing is important, therefore worth doing right. Dedication goes hand in hand with our missions. We are problem solvers and innovators; commanders of communication and collaboration. We run toward the challenge, not away from it. We take pride in our strength and dignity, our compassion and patience. We are strong individuals who come together in an awe-inspiring team.
We are smart people. We are bright ideas. We are powerful results.
We are Patrick.
