About Us
Stevens takes pride in offering and delivering quality services from the planning phase through the construction phase.
Unlike large companies that provide specialists in all areas of engineering, we employ staff that can cover multiple areas of engineering that are used on a routine basis. Stevens’ size allows us to collaborate internally to better define and implement change more decisively and quickly. Our efficient organizational structure will never bog down your project.
Founded in 1973, our substantial portfolio includes state, local and private site planning, design and construction administration. We understand that adaptability is critical to the success of your project. At Stevens, we deliver large-firm knowledge and experience at a smaller more flexible size. We focus on building lasting relationships with our clients, and strive to provide high-quality services, responsiveness and personal attention which exceed expectations.
We approach each project with honest, open communication; taking the time to listen to and understand your needs. We recommend quality solutions to best fit your project and address your long-term needs and budgetary requirements. We offer the advantage of direct access to the owners and project managers who work closely with you from the early planning stages through project completion. We measure the success of a project by function, value and ultimately our clients’ satisfaction in the service we delivered.
At Stevens, community is integrated in our culture. We believe that giving back to communities is one of the most rewarding and enjoyable parts of our jobs. Our team actively volunteers in a wide variety of community service projects from professional organizations to charities.
