Celebrating 20 years of client-first service in St. Louis!
CEC St. Louis was established in 2001 with an initial focus on environmental site assessment. Within our first five years, we grew our service offerings to include environmental remedial design and remediation oversight, ambient air sampling, air source testing, and environmental compliance. Soon after, we added civil engineering services and expanded our air quality services for clients in electric generation and utilities. In 2013, we had a significant expansion of multiple practices serving solid waste clients, and we began providing engineering and environmental services support to the mining industry. We soon added ecological services to our lineup. In 2018, we established a presence and office space in the Kansas City area, and in 2022, our growth continued through the acquisition of Pickett, Ray & Silver, Inc. (PRS). PRS is a civil engineering and land survey firm that has provided planning and engineering services for clients throughout Missouri, Illinois, and Kansas. We take pride in the breadth of services we offer to our strong client base in the real estate, mining, manufacturing, solid waste, public sector, and power markets. Come see us in our new, expanded location in St. Charles, MO.
The office is currently ranked #12 among St. Louis’ Largest Environmental Consulting Firms by the St. Louis Business Journal.
The CEC St. Louis culture is supportive with a personal small-firm feel. The mix of seasoned, experienced consultants and younger professionals creates an environment to mentor, collaborate, and learn from one another with a common goal: success for each other as well as for our clients. We organize regular employee activities such as potluck lunches, the annual Chili Cook-Off, and an annual Christmas party. We also like to have personal and fun connections with our clients—ask us about our annual Cardinals baseball game outing!
CEC St. Louis is committed to giving back to the community. Around Thanksgiving, we collect food for the St. Louis Food Bank. Around Christmastime, we collect items for Toys for Tots or similar initiatives, such as the Salvation Army’s “Adopt a Family” program. Aside from holiday activities, we support events at the Sparrow’s Nest, a local maternity home; donate to local high school robotics programs; hold a one-day mentoring event for local high school engineering students; and participate in a wetland stream cleanup program.
