About Professional And Scientific Associates, Inc.

Professional And Scientific Associates, Inc. (doing business as PSA), a minority-owned, woman-owned small business headquartered in Arlington, Virginia, delivers international program support, event planning, logistics coordination, and specialized advisory services to federal agencies as a prime contractor, competing predominantly full-and-open on the GSA Multiple Award Schedule without set-aside restrictions at the task-order level, though the vendor's underlying master vehicles frequently carry small-business set-aside designations.

PSA's footprint spans 4,254 prime awards since 1992 with combined potential value of $2.22 billion and $391.1 million in obligated dollars. The vendor operates across 76 distinct federal customer agencies, with concentration anchored by two dominant relationships: the Department of Commerce Office of the Secretary (1,965 awards, $249.6 million) and the Department of Health and Human Services, principally the NIH Office of Logistics and Acquisition Operations (12 awards, $825.1 million) and the CDC Office of Acquisition Services (423 awards, $707.6 million). The dollar concentration diverges sharply from volume concentration—HHS vehicles dominate potential value at 86% of combined dollars despite representing a minority of award count, driven by PSA's $100 million single-award Indefinite Delivery Contract with NIH for conference and administrative travel services through November 2029 and an $18 million single-award Blanket Purchase Agreement with the Department of Transportation's Office of the Secretary for global program support through September 2029.

Capability portfolio centers on event logistics, international workshop facilitation, training program development, translation and interpretation services, and subject matter expert advisory support. Representative recent prime work includes a $262 thousand delivery order for PTC U.S. consultations and margin sessions (Commerce, July 2026); a $236 thousand regional 5G workshop for Latin America (Commerce, February 2026); a $200 thousand U.S. satellite consultation engagement (Defense Office of the Secretary, July 2026); a $180 thousand translation and interpretation call (Defense Office of the Secretary, June 2026); and a $159 thousand Europe regional translation contract (State, March 2026). Task-order ceiling values range from under $10 thousand to approximately $260 thousand, with the majority clustered between $30 thousand and $90 thousand. Geographic footprint spans Southeast Asia (Malaysia, Maldives, Philippines, Vietnam, Sri Lanka), Central Asia and South Caucasus (Kazakhstan, Uzbekistan, Mongolia, Azerbaijan, Armenia, Georgia), Eastern Europe and the Balkans (Ukraine, Kosovo, Albania, Bosnia, Montenegro, Poland), North Africa and the Middle East (Morocco, Tunisia, Egypt, Iraq), Latin America (Colombia, Bolivia, El Salvador, Guatemala, Dominican Republic), and select developed markets (Canada, Australia, Sweden). Work is performed worldwide with administrative oversight primarily at Arlington, Virginia and Washington, DC.

GSA Schedule labor portfolio spans 23 active categories at hourly rates from $38.43 (Clerk, high school, no clearance) to $217.53 (Senior Technical Advisor, bachelor's, 12 years experience, no clearance required). No security-cleared positions are offered. Representative mid-tier offerings include Meeting Coordinator I ($69.76/hr), Graphics Artist I ($85.76/hr), Senior Consultant/Meeting Planner ($104.11/hr), and Project Director II ($117.54/hr). Rate posture aligns with administrative and logistics-heavy service delivery: median government-paid hourly rate under SCI reporting is $279.14/hr, with 90th percentile at $1,078.84/hr, indicating senior advisory and specialized roles command premium pricing when delivered under service-contract-reportable engagements.

Vehicle positioning concentrates on the GSA Multiple Award Schedule (2,561 task orders, $414.2 million) and subordinate vehicles including GSA's Professional Services Schedule (1,681 task orders, $95.2 million) and the Federal Supply Schedule GS23F0082K (1,221 task orders, $275 million), plus the $100 million NIH conference and travel contract and the $18 million Transportation Department small-business-set-aside BPA. Recent activity shows steady volume—182 awards in 2026 (partial year), 162 in 2025, 323 in 2024—with modest recompete exposure: 169 awards ($13 million combined potential value) reaching ultimate completion within the next twenty-four months.

Service Contract Inventory data capture only $1.5 million in invoiced federal services revenue across FY2022–FY2024 (2.0 FTEs in FY2022, 0.4 in FY2023, 0.0 in FY2024), reflecting SCI's narrow scope—contracts above the $150 thousand threshold only, excluding goods, products, and the bulk of PSA's task-order volume, which typically falls below that reporting floor. SCI represents a partial slice of PSA's federal services footprint and does not reflect total enterprise federal or commercial revenue.

Teaming pattern shows PSA as a pure prime: 100% of awards are prime contracts or IDVs; 0% are subcontract positions. The vendor does not subcontract within SCI-reportable engagements (0% sub-hours share across prime contracts). Subcontracting activity, if present, appears in smaller task orders beneath SCI visibility.

Primary NAICS alignment: Public Relations Agencies (2,057 awards), Convention and Trade Show Organizers (1,313 awards), and Office Administrative Services (394 awards), with secondary presence in management consulting. Primary PSC alignment: Support–Management: Logistics Support (2,220 awards) and Support–Administrative (516 awards), reflecting the operational focus on event logistics, meeting planning, and international program coordination rather than specialized technical delivery or professional consulting at scale.
