Professional And Scientific Associates, Inc.

Professional And Scientific Associates, Inc., doing business as PSA, is a minority-owned, woman-owned small business based in Arlington, Virginia, that operates as a prime contractor delivering international program support, event logistics, workshop facilitation, and specialized advisory services to federal agencies worldwide. PSA competes predominantly full-and-open on the GSA Multiple Award Schedule and through related blanket purchase agreements, with no set-aside restrictions at the task-order level, though the vendor holds underlying small-business certifications on several master vehicles. As a Subchapter S corporation classified as both a Woman Owned Small Business and a Self-Certified Small Disadvantaged Business, PSA operates entirely as a prime—4,374 awards with zero subcontracting footprint—delivering work on a pure-delivery model with no named subcontractors across its federal portfolio.

PSA's concrete capability portfolio centers on event planning, logistics coordination, and international program facilitation. Representative work includes a $262 thousand PTC U.S. consultations engagement for the Department of Commerce (July 2026), a $180 thousand translation and interpretation delivery order for the Department of Defense Office of the Secretary (June 2026), a $200 thousand U.S. satellite consultation for Defense (July 2026), a $125 thousand Southeast Asian ASEAN Manila port security engagement for the Transportation Department (June 2026), and dozens of workshop, conference, and regional program-support orders clustered between $30 thousand and $90 thousand. Across this work, PSA demonstrates recurring capability in international workshop facilitation, translation and interpretation services, subject matter expert advisory support, training program development, and logistics coordination for government-to-government and government-to-private-sector capacity-building initiatives spanning Southeast Asia, Central Asia, Eastern Europe, North Africa, the Middle East, and Latin America.

Customer concentration is dramatic and skewed. The Department of Commerce Office of the Secretary dominates by award count—2,079 awards at $265.5 million combined potential value—but the National Institutes of Health Office of Logistics and Acquisition Operations anchors the dollar portfolio with just 11 awards carrying $825.1 million in combined potential value, driven by a single $100 million indefinite-delivery contract awarded December 1, 2024, for conference and administrative travel services through November 2029. The CDC Office of Acquisition Services places the second-largest dollar volume at $707.6 million across 423 awards. These three customers alone represent 86 percent of the vendor's combined potential value across 76 federal agencies served. The concentration in NIH and CDC reflects PSA's dominant role on healthcare-sector conference and logistics infrastructure, while the Commerce concentration reflects decades of international program support and event coordination work.

PSA's vehicle position is anchored to the GSA Multiple Award Schedule, the primary vehicle under which 2,790 task orders carry $436.2 million in potential value. The vendor also holds seat on the Professional Services Schedule (1,681 orders, $95.2 million), Federal Supply Schedule GS23F0082K (1,221 orders, $275 million), and a series of blanket purchase agreements including one with the Transportation Department worth $18 million through September 2029 and another with NIH worth $100 million through November 2029. Within these vehicles, PSA receives task orders across all three primary contracting mechanisms—GSA Schedule BPA calls, delivery orders, and direct purchase orders—for event logistics, translation services, subject matter expert advisory support, and training facilitation.

Activity trajectory shows modest growth interrupted by a sharp decline. PSA executed 296 awards in 2022, 289 in 2023, and 323 in 2024, then dropped to 162 in 2025 before recovering to 302 in 2026. The decline in 2025 likely reflects a shift in ordering patterns post-NIH contract award; most recent activity is concentrated in the Transportation and Commerce departments' international program initiatives and NIH travel-services orders. The recompete cliff presents minimal risk: 235 awards with ultimate completion in the next twenty-four months carry only $18.2 million in combined potential value—a rounding error relative to the vendor's $2.24 billion total portfolio.

SCI-reported service-contract activity reveals a vendor whose invoicing on federal services contracts above the $150,000 threshold peaked in FY2022 at $1.2 million across 2.0 FTEs, declined to $289 thousand in FY2023 across 0.4 FTEs, and dropped to zero reported invoicing in FY2024 and FY2025. This collapse in SCI-reportable revenue does not reflect actual business decline—the vendor's award count and potential-value footprint remain robust—but rather a shift in task-order structure. PSA's largest contracts (the $100 million NIH IDIQ and the $825.1 million CDC portfolio) are housed under IDIQs and blanket purchase agreements where task-order invoicing may fall below or be structured outside the $150,000 SCI threshold. Government-paid hourly rates on SCI-reportable contracts span a wide spectrum: median around $279 per hour, with senior advisory positions commanding rates through $1,078 per hour. The vendor's active GSA Schedule labor portfolio spans 30 categories from Clerk at $38.43 per hour to Senior Technical Advisor at $217.53 per hour, covering administrative, logistics, design, language services, and program-management roles, with no security-cleared positions offered.

The teaming pattern is unambiguous: PSA operates as a pure prime across all federal work with zero subcontracting. Across SCI-reportable prime contracts, the average sub-hours share is zero percent—the vendor builds and staffs its own delivery teams entirely. This profile positions PSA as a feeder prime on larger multi-vendor vehicles and a favored logistics and program-support partner for Commerce and Health agencies, but not as a typical subcontractor or joint-venture participant. For business development purposes, PSA represents a stable, high-volume administrative and logistics services vendor anchored to GSA vehicles and specialized in international program facilitation, with customer concentration so acute (NIH, CDC, and Commerce represent 86% of dollars) that pipeline diversification represents the primary strategic challenge.

With over 30 years of Federal and private sector event management experience, PSA has seen and produced almost any type of event imaginable. We have experience coordinating up to 4,000 events annually. We have managed events ranging in size

from 15 to 15,000 attendees. We can coordinate small event series, like trainings and webinars,

as easily as we can execute a 6,000 attendee Forum, drawing participants from all over the

world. Our experience has led to the crafting and honing of standard operating procedures, time tested and proven, which we employ in all of our business associations.

Additionally, PSA provides healthcare focused communication support. For more than 20 years PSA has provide communication support to the HHS with services ranging from development of Public Service Announcements to full blown social media campaigns.
