September 26th, 2025

We are pleased to announce the opening of Loureiro’s newest office in St. Louis, Missouri—a milestone for a team that has been delivering standout environmental engineering work in the region for years.
Led by Office Manager (PE/PG) Derek Ingram, the St. Louis team includes approximately ten team members among them Field Operations Manager Reggie Gardner and Senior Project Manager Brendan Wilder. Their expertise spans some of our most complex remediation projects, including work recognized in Pulse Q2 as a model for integrating safety into every stage of design, construction, and operation.
This group is also advancing industry innovation with Loureiro’s innovative approach to in-situ remediation of Coal Combustion Residual (CCR) and patent-pending Colloidal Carbon Injection for In-Situ Filtration of Drinking Water, alongside other technically advanced solutions for utility and government-sector clients.
A dedicated office not only supports the team’s growth, it reinforces our commitment to the Midwest and positions Loureiro for continued success in this important market.
