Marsh & Associates LLC

Marsh & Associates LLC, doing business as Marsh, is a veteran-owned small business based in Tempe, Arizona, that delivers environmental monitoring, native fish population assessment, and aquatic ecosystem conservation services to federal agencies as a prime contractor (98% of recent awards), operating predominantly under total small business set-asides across Department of the Interior bureaus.

Marsh's customer base is heavily concentrated within Interior. The Bureau of Reclamation accounts for 80% of awards (43 awards, $11 million combined potential value) and 99% of combined potential value when paired with a single GSA Federal Acquisition Service vehicle. The Fish and Wildlife Service Region 2, U.S. Geological Survey Office of Acquisitions and Grants, and National Park Service Pacific West Region represent secondary Interior relationships, with the Forest Service Southwestern Region a tertiary customer. This concentration reflects Marsh's specialized expertise in Colorado River Basin and southwestern native fish conservation — a niche where the vendor has operated since 2004 with a track record of repeat awards at escalating dollar values.

Marsh's capability footprint centers on endangered-species monitoring, field population assessments, aquatic data management, and specialized equipment delivery for native fish conservation. Representative work includes a $1.24 million definitive contract through February 2030 with Bureau of Reclamation for Lake Mohave Razorback Sucker monitoring (monthly data collection and population-dynamics reporting); a $794,974 delivery order under GSA Multiple Award Schedule for Gila River Basin Native Fish Monitoring through March 2027; a $130,643 small business set-aside purchase order with Bureau of Land Management Arizona Region for Bonita and Aravaipa Creek nonnative fish removal; and recent 2026 awards totaling roughly $120,000 for submersible PIT (Passive Integrated Transponder) scanning equipment and native fish database services. The vendor also delivers specialized submersible antennas, batteries, and field accessories to USGS and manufactures or distributes custom aquatic monitoring hardware meeting depth and portability specifications unique to remote southwestern waterways.

Marsh places 28 task orders through GSA Multiple Award Schedule (combined potential value $6.6 million) and 11 through The Professional Services Schedule, with a smaller IDC vehicle (Indefinite Delivery Contract INR07PG322011) generating four task orders. Recent activity shows moderate volatility — four awards in 2021, declining to one in 2024, then recovering to two in 2025 and three in 2026. Three awards (combined potential value $871,000) reach ultimate completion within the next twenty-four months, creating recompete risk in that window. The vendor invoiced $1.5 million across SCI-reportable prime contracts in FY2022–FY2024, averaging 3.2 FTEs per year, with government-paid median rates around $74.50 per hour and senior leadership labor priced through $169.61 per hour. Marsh does not employ subcontractors on SCI-reportable contracts and operates as a prime on 98% of its federal award footprint. GSA labor categories span entry-level fisheries assistants ($28.96/hr) through executive management ($169.61/hr), with titles reflecting aquatic science and program-management specialization. A related 501(c)(3) nonprofit, Marsh Education, has received federal grants for native fish conservation outreach. Marsh holds one federal grant sub-award with the University of New Mexico, supporting genetic database maintenance and specimen cataloging for razorback sucker and bonytail populations under the lower Colorado River remote sensing program.
