F.x. Masse Associates, Inc.

F.x. Masse Associates, Inc., operating as FX Masse Associates, is a self-certified small disadvantaged business delivering radiation safety officer, health physicist, and diagnostic medical physicist services to the Department of Veterans Affairs as a prime contractor exclusively under total small business set-asides. The firm, a Subchapter S corporation based in Danvers, Massachusetts, competes 100% of its federal work as a prime and has served a single customer agency — the VA's Veterans Integrated Service Network 1 — across 44 awards since 2006.

FX Masse Associates specializes in nuclear radiation health physics, medical equipment testing, compliance, and radiation safety program management at VA medical facilities across the northeastern United States. Representative work includes a $436,234 physicist services contract awarded October 1, 2025, to the VA Boston Healthcare System in Jamaica Plain covering annual equipment performance testing, radiation protection surveys, dose assessments, 24/7 emergency support with 30-minute telephone and 2-hour on-site response capability, and technical oversight for X-ray, CT, MRI, mammography, and nuclear medicine equipment through September 2030; a $287,983 physicist service contract awarded September 4, 2024, for radiology equipment inspection and calibration services at Danvers, Massachusetts, through September 2028; and a $99,647 purchase order awarded October 3, 2026, for physicist and health safety officer services at Manchester VAMC in New Hampshire, including radiation safety training, calibration of radiation detection instruments, shielding integrity checks, and comprehensive testing of x-ray, nuclear medicine, and non-ionizing imaging equipment through October 2031. All contracts require contractor employees to hold necessary NRC, NHPP, and Joint Commission licenses and certifications; subcontracting is prohibited across the portfolio.

The vendor's customer concentration is absolute: VISN 1 accounts for 35 awards representing $3.3 million in combined potential value, or 97% of the vendor's total federal award portfolio. Recent activity has been sparse — one award in 2021, none in 2022, one in 2023, three in 2024, two in 2025, and one in 2026 — suggesting either episodic recompete cycles or a limited set of underlying requirement positions. Two awards (combined potential value $538 thousand) reach ultimate completion within the next twenty-four months and face recompete exposure. The vendor's Service Contract Inventory footprint is minimal: $83 thousand in invoiced prime revenue across FY2023 only, with 0.2 FTEs reported, reflecting SCI's reporting threshold of $150,000 and the fact that most awards fall below that ceiling. Median government-paid rates on SCI-reportable work ran $264.33/hr. Across the SCI-reportable prime contracts, FX Masse Associates performed 0% of hours through subcontractors, building its own delivery teams without sub engagement.
