STETSON ENGINEERS INC

Stetson Engineers Inc. delivers specialized technical and legal support services to federal agencies, with a strong emphasis on expert witness testimony, environmental modeling, and scientific research. The firm’s core capabilities center on providing high-level technical analysis and litigation support in environmental science and engineering, including numerical modeling of nutrient transport, water quality testing, and environmental risk assessment tools. Their work often bridges complex scientific data with legal proceedings, offering defensible, peer-reviewed analyses that support regulatory compliance and judicial outcomes. Key differentiators include deep expertise in environmental modeling frameworks, scientific communication for non-technical audiences, and the ability to translate engineering data into actionable legal testimony. The company maintains a consistent relationship with the Department of Justice, where it frequently serves as an expert witness in environmental, regulatory, and technical litigation matters. It also supports the Department of Defense on environmental research initiatives and the Department of the Interior on public land management projects. These engagements reflect a pattern of trusted, repeat partnerships built on precision, credibility, and adherence to federal scientific standards. Stetson Engineers primarily operates under NAICS 541199 (other legal services), reflecting its unique role in providing science-based expert testimony, and 541330 (engineering services), indicating its foundational technical capacity. Additional work in environmental consulting and physical sciences research positions the firm at the intersection of law, engineering, and environmental science—serving niche markets requiring rigorous technical validation in legal and regulatory contexts. Based in San Rafael, California, Stetson Engineers Inc. is a small, privately held firm with no federal certifications listed. Its geographic proximity to federal judicial and environmental regulatory hubs enhances its ability to respond rapidly to litigation and agency needs across the western United States.
