About the company
Stetson Engineers Inc., a San Rafael, California-based environmental consulting firm, provides expert witness services, water resources engineering, and environmental monitoring to federal agencies as a prime contractor on a full-and-open (non-set-aside) basis. The firm operates across 160 prime awards with no subcontract footprint, competing entirely in the unrestricted federal marketplace.
Stetson Engineers' capability portfolio centers on expert witness testimony and technical analysis in environmental and water litigation, water quality testing and environmental modeling, and water resources engineering support for federal environmental matters. Representative prime work includes a $5.69 million delivery order from the U.S. Marine Corps for water litigation services at Camp Pendleton, awarded June 6, 2022, under the GSA Multiple Award Schedule; a $1.26 million time-and-materials purchase order from the Department of Justice's Justice Management Division for expert witness services through February 1, 2028, awarded April 17, 2023; and a $489,886 firm fixed-price purchase order from Naval Information Warfare Systems Command for numerical modeling of nutrient transport and water quality testing, awarded August 9, 2023. The firm also holds a GSA Federal Supply Schedule contract with a $4.4 million ceiling through July 15, 2029, under which federal civilian and defense agencies issue task orders for environmental consulting and water litigation support.
Customer concentration is split between litigation-heavy civilian agencies and defense customers. The Department of Justice's Environment and Natural Resources Division dominates by award count (53 awards, $9.1 million combined potential value), but the U.S. Marine Corps anchors the potential-value rankings with 12 awards carrying $15.2 million. The GSA Federal Acquisition Service ranks second in potential value ($12.9 million across two awards — the FSS contract and underlying task orders), followed by DoJ Environment and Natural Resources, the Army Corps of Engineers Sacramento District ($5 million on a single award), and DoJ Justice Management Division ($1.9 million). The top five customer lines account for 86% of combined potential value and 62% of award count, indicating concentration in litigation and water-resources expertise rather than breadth.
Stetson Engineers places work primarily under the GSA Multiple Award Schedule (22 task orders, $16.2 million combined potential value) and holds positions on indefinite-delivery contracts with Naval commands (Indefinite Delivery Contract INISMP00050139, 4 task orders; Indefinite Delivery Contract 539A2801N34, 3 task orders). The firm's award portfolio spans 94 awards categorized under "All Other Legal Services" (NAICS) and 75 awards coded to "Support—Professional: Expert Witness" (PSC), with secondary depth in Environmental Consulting Services (36 awards) and Engineering Services (8 awards), reflecting a business model anchored in litigation support rather than infrastructure or systems engineering.
Activity has been episodic. Awards per year averaged roughly 3.2 over the last five years (2022–2026), with 5 awards in 2022, a decline to 3 in 2023, recovery to 5 in 2024, then a sharp drop to 1 in 2025 and 2 in 2026. Eight awards totaling $9 million combined potential value reach ultimate completion within the next twenty-four months and therefore face recompete exposure. The firm has served 18 distinct customer agencies across its 160-award portfolio, with combined potential value of $51.5 million and $41.8 million obligated (81% execution rate), indicating sustained federal engagement in specialized water litigation and environmental expert services since at least 1999.
