What CT Consultants does
CT Consultants is a U.S.-based environmental science and engineering consulting firm founded in 1922 and headquartered in Mentor, Ohio, now operating as a subsidiary of Verdantas under the brand 'CT Consultants, a Verdantas Company.' The firm delivers integrated solutions that blend environmental science with engineering disciplines including architecture, automation, geotechnical, hydrology, civil, structural, mechanical, and water/wastewater systems engineering. Its core service offerings span CERCLA/RCRA remediation, environmental assessment, environmental health and safety, natural resources planning, sustainability advisory, and Superfund project coordination, with three formally designated Key Differentiators (River and Flow-Related Solutions, Digital Technologies, and Superfund Project Coordination & Liability Management) and three Growth Accelerators (Stormwatershed 360, Data Centers, and Recreation & Resort Development).
The firm serves a hybrid customer base that spans a primary Federal Government vertical — most notably demonstrated by the December 2025 award of a $300 million environmental services contract to FE-CT JV, LLC (a joint venture with First Environment, Inc.) covering NEPA compliance, cultural assessments, and environmental investigations across more than 1,500 U.S. Department of Veteran Affairs facilities — and a horizontal portfolio across Power Delivery, Water, Industrial, Renewable Energy, Transportation, Power Generation, Technology, Real Estate, and Oil & Gas markets.
CT Consultants generates revenue through professional services contracts, primarily via direct federal procurement channels as evidenced by its dedicated Plan Room (bids.verdantas.com) and the FE-CT JV federal award, supplemented by enterprise engagements across infrastructure and industrial markets. Pricing is not publicly disclosed but is determined through competitive procurement processes. The firm employs 251-500 people and operates with a Verdantas parent platform that includes offshore delivery capacity in India and is actively executing a regional roll-up strategy (e.g., the June 2026 acquisition of Yu & Associates).
