Stuart B. Consultants, Inc.

Stuart B. Consultants, Inc. (doing business as Birnbaum Interpreting Services), a minority-owned, self-certified small disadvantaged business based in Chevy Chase, Maryland, provides American Sign Language interpretation, video remote interpreting, real-time captioning (CART), and spoken language interpretation services to the federal government exclusively as a prime contractor across 93 distinct federal agencies. The vendor operates as a 100% prime contractor with no subcontractor footprint and competes in full-and-open federal markets without reliance on set-aside categories, though many individual awards carry Total Small Business or competitive small-business designations.

Birnbaum's capability portfolio centers on language accessibility services across on-site and remote modalities spanning over 150 languages. Concrete representative work includes a $1.61 million firm fixed-price delivery order from the FDA for remote conference captioning services through December 2027; a $727.68 million delivery order from the National Institute of Standards and Technology for sign language interpreting and real-time captioning through April 2028; and a $2.95 million delivery order from the Office of the Chief Information Officer for CART and video remote interpreting through February 2027. Recent 2026 awards include a $43,680 BPA call from NASA Marshall Space Flight Center for sign language interpretation and captioning in Huntsville, Alabama, and a $109,140 BPA call from the Justice Management Division for Federal Relay Services through September 2027.

Customer concentration is heavily concentrated in civilian federal IT and administrative agencies. The top five customers by award count cover 53% of the vendor's recent awards and are led by the Department of the Treasury Internal Revenue Service (184 awards, $53.8 million combined potential value), which alone represents 28% of total award count and 28% of combined potential dollars. The rankings by potential value and award count diverge slightly: the Architectural and Transportation Barriers Compliance Board (34 awards) anchors volume, while the Executive Office of the President Office of Administration (4 awards, $10.7 million) and Naval Sea Systems Command (29 awards, $6.8 million) carry the largest individual order values.

Birnbaum holds a dominant position on the GSA Multiple Award Schedule (MAS) with a $23.12 million Federal Supply Schedule contract awarded January 2022 and running through January 2027—the primary vehicle through which the vendor reaches federal agencies. This Schedule carries 311 task orders worth $81.6 million in combined potential value. Additionally, the vendor maintains multiple single-award and multiple-award BPAs under the Schedule: a $10 million interpreting and captioning services BPA with the Office of Administration (active March 2023 through March 2028); a $5 million single-award BPA with Naval Sea Systems Command (June 2024–June 2029); a $2.41 million Federal Relay Services BPA with the Justice Management Division (February 2022–September 2032); a $1.5 million sign language interpreting BPA with the Assistant Secretary for Financial Resources (August 2022–August 2027); and a $750,000 ASL/CART BPA with the Consumer Financial Protection Board (December 2022–December 2027). The vendor also holds two IDIQs under Treasury-managed vehicles (TIRNO01D00001 and TIR960002) carrying 26 and 14 task orders respectively and totaling $21 million in combined potential value.

Activity has declined year over year—30 awards in 2022 down to 8 in 2026 (through October)—though this reflects the shift in procurement strategy toward larger, longer-duration vehicles and fewer, higher-value task orders rather than sustained volume decline. Twenty-two awards with a combined potential value of $11.1 million face ultimate completion within the next twenty-four months, presenting recompete exposure across the GSA Schedule and scattered agency-specific BPAs.

SCI-reported invoicing totaled $4.6 million across FY2022–FY2025, with FY2024 peaking at $1.6 million across 7.5 FTEs. Government-paid hourly rates on federal services contracts captured in SCI run a median of $114.20 per hour, with the spectrum spanning from $93.92/hr at the 10th percentile through $126.37/hr at the 90th percentile. The vendor self-performs all work with zero sub-hours share across SCI-reportable prime contracts. SCI represents only a narrow slice of the vendor's federal footprint—the $4.6 million in SCI dollars covers service contracts above the $150,000 threshold and excludes the vendor's substantial volume of small delivery orders, BPA calls, purchase orders, and other work below the reporting floor.
