What Gonzalez Companies does
Gonzalez Companies, LLC is a privately held civil engineering and construction management firm founded in 1999 and headquartered in St. Louis, Missouri. The firm delivers planning, design, construction management, inspection, and maintenance services across seventeen practice areas, including bridge inspection, transportation, water and wastewater, stormwater management, hydraulics, geotechnical engineering, survey, and design-build, for federal, state, and local government agencies, sewer districts, and private clients throughout the Midwest. It operates from 15 office locations in Missouri, Illinois, Texas, Kentucky, Indiana, and Ohio, and reports over 230 employees and a stated 98%+ client satisfaction rate. Revenue is generated through custom-priced, project-based professional services contracts, including multi-year engagements, secured via competitive bidding, RFPs, qualifications-based selection, and long-term client relationships with agencies such as IDOT, MoDOT, the Illinois Tollway, and the Metropolitan Sewer District.\n\nThe business is integrated with the broader Trilon Group platform under a 2023 strategic partnership, through which Gonzalez retains its brand and operating identity while accessing consolidated capabilities and M&A support. The firm has executed two acquisitions in ten months: RA Consultants in August 2024, adding water and wastewater depth and Ohio/Kentucky offices, and FPBH, Inc. in April 2025, adding Indiana offices and approximately 16 professionals. Gonzalez carries no proprietary software platform, patents, or disclosed AI capabilities; its competitive positioning rests on licensed engineering talent, multi-state office coverage, state-DOT and tollway prequalifications, and a track record of award-winning public-sector project delivery.\n\nManagement is led by President and COO Barry P. Grant (joined 2022), CFO Timothy Pierce (joined October 2021), Chief Growth Officer R. Patrick Judge, Chief Revenue Officer Terry Adams, and Vice President of Business Operations Hank Sikorski (joined 2024 with a mandate for organic and inorganic growth). The firm has won multiple ACEC Engineering Excellence awards (Illinois 2022 and 2024; Missouri 2024) and a 2017 Quality Concrete Award, and runs a 100% cost-free mentorship program for youth interested in engineering.
