About the company

Stell Environmental Enterprises Inc., doing business as Stell, is a Redmond, Washington–based SBA 8(a) certified women-owned small business that delivers cultural resource management, archaeological surveys, environmental consulting, and engineering services to federal agencies as a prime contractor (99% of recent awards). Stell holds concurrent SBA designations as a women-owned small business, service-disabled veteran-owned small business (SDVOSB), and economically disadvantaged women-owned small business (EDWOSB), and operates under primary NAICS categories 541620 (Environmental Consulting Services), 541710 (Research and Development in the Social Sciences and Humanities), and 541330 (Engineering Services).

Stell's customer concentration is heavily tilted toward the Army Corps of Engineers. The Department of the Army Corps of Engineers Engineering District Mobile anchors 79% of the combined potential value across the top five customer agencies (26 awards, $660.9 million potential), followed at distance by the Corps of Engineers nationally ($93.3 million across 17 awards), the Seattle District ($77.5 million, 11 awards), the Albuquerque District ($60.9 million, 8 awards), and the Fort Worth District ($44.2 million, 44 awards). Within the top five agencies by award count, the Fort Worth District leads volume (44 awards, $44.2 million potential), but the Mobile District dominates the dollars-per-award ratio by a factor of twenty-five. The top five customer agencies account for 39% of all awards but 79% of combined potential value, signaling severe concentration risk on a single USACE district and subordinate exposure to recompete and budget fluctuation.

Stell's capability portfolio centers on Class I, II, and III cultural resource inventories and archaeological surveys across federal land-management and military installations; environmental compliance consulting, including spill prevention and control plan (SPCC) updates, storage tank integrity testing, and water quality support; Section 106 compliance and National Historic Preservation Act coordination; and environmental engineering and planning services. Representative prime contracts include a $12.6 million REM Services and Installation Management Command (IMCOM) sustainment delivery order from the Army Corps of Engineers Engineering Support Center Huntsville through September 2029 for environmental compliance and conservation support; a $1.1 million archaeological inventory from the Bureau of Land Management Oregon-Washington Region for the Adel, Oregon area through June 2027 under the GSA Multiple Award Schedule; a $249 million architect-engineer services IDIQ from the Army Corps of Engineers Mobile District (ultimate completion December 2029) supporting Planning and Environmental Division programs; an $8.0 million Air Force Community Partnership delivery order from the Air Force Materiel Command through March 2025; and a $7.8 million Air Force Community Partnership delivery order from the Air Force Civil Engineer Center through June 2026. Across the SCI-reportable service-contract subset (FY2023–FY2025), Stell invoiced $1 million with government-paid median hourly rates around $54.63/hr, spanning a spectrum from $14.01/hr (10th percentile) to $80.09/hr (90th percentile).

Vehicle positioning spans multiple Army Corps of Engineers IDIQs, GSA MAS, and Forest Service BPAs. Stell holds seat on a $45 million women-owned small business IDIQ multiple-award task order contract with USACE Seattle District (April 2026–March 2029) for environmental consulting services; a $40 million women-owned small business IDIQ for three regional cultural resources services matocs through May 2031, issued December 2025 by USACE Engineering and Support Center St. Louis; a $249 million architect-engineer services IDIQ from USACE Mobile District (no set-aside, through December 2029); a $15 million total-small-business-set-aside IDIQ for architectural master planning and studies with the National Institute of Standards and Technology (July 2025–July 2027); a $7 million single-award BPA with the Forest Service Southern Region for environmental consulting services (through March 2028 under GSA MAS); and a $500 thousand single-award BPA with USDA NRCS Northeast Region for cultural resources Phase 1A/1B services (through July 2025). The top five parent vehicles by task-order frequency are five Department of Defense and Army Corps of Engineers IDIQs, with the leading vehicle carrying 33 task orders and $9.8 million combined potential value. Across the GSA Schedule, Stell maintains 19 labor categories spanning Environmental Scientist through Program Manager, with hourly rates from $77.15 to $267.35, all requiring a bachelor's degree and no security-clearance offerings.

Activity has modulated in recent years—17 awards in 2022, rising to 19 in 2023, declining to 16 in 2024, then to 9 in 2025 and 10 in 2026—reflecting seasonal and project-driven award timing rather than sustained growth or contraction. Twelve awards (combined potential value $3.1 million) face ultimate completion inside the next twenty-four months and will trigger recompete exposure. Stell operates predominantly as a prime contractor and builds its own delivery teams; SCI data shows an average 1% sub-hours share across prime contracts, indicating minimal subcontractor engagement on federal service work. Stell subcontracts to Marstel-Day LLC (archaeological evaluation and quality control at Hampton National Historic Site), Weston Solutions Inc. (NEPA environmental assessment support for USCG Air Station Port Angeles), and Leidos Inc. (energy and water benchmarking services through September 2026). The 99% prime-to-sub split and minimal sub engagement suggest Stell performs the majority of work in-house and does not function as a feeder for larger primes.
