Symphony Diagnostic Services NO. 1, LLC

Symphony Diagnostic Services NO. 1, LLC, doing business as Tridentcare (also operating under the trade name Mobilex USA), is a for-profit diagnostic imaging services provider based in Hunt Valley, Maryland, that delivers mobile ultrasound, portable x-ray, and radiology services to federal correctional institutions and military medical facilities as a prime contractor (100% of recent awards) on firm fixed-price purchase orders with no socioeconomic set-aside designations.

The vendor's federal customer base concentrates heavily within the Department of Justice Bureau of Prisons system, with 26 of 37 recent awards (70% of award count) distributed across four named facilities: Federal Correctional Institution Bennettsville (12 awards, $218 thousand combined potential value), United States Penitentiary Big Sandy (11 awards, $26 thousand), Federal Correctional Institution El Reno (8 awards, $34 thousand), and Federal Correctional Institution Williamsburg (3 awards, $36 thousand). The Defense Health Agency anchors the vendor's dollar concentration with 2 awards valued at $302 thousand combined potential value — a $154,600 small-business-set-aside purchase order for two-view chest x-ray services at the Branch Health Clinic Philadelphia (awarded May 2024, running through May 2029) and a prior $747,000 five-year fixed-price contract for chest x-rays and interpretations in support of occupational health surveillance at the Philadelphia Navy Yard. The Army Medical Command and Federal Detention Center SeaTac complete the customer set. No named parent contract vehicles structure the portfolio; the vendor operates under individual purchase orders, with one Indefinite Delivery Contract (DJBP050700000013) supporting 7 task orders valued at $14 thousand combined. Capability work is consistently framed around portable medical diagnostics: $89,890 for Trident x-ray imaging services across multiple months at FCI Bennettsville (October 2024), $27,988 for mobile x-ray services at FCI Bennettsville (June–September 2024), $25,781 for mobile x-ray services at FCI Bennettsville (July 2024), and monthly ultrasound and imaging service task orders at Big Sandy and Bennettsville ranging from $1,135 to $6,000. NAICS 621512 (Diagnostic Imaging Centers) governs 29 of 41 awards; PSC Medical-Radiology covers 21 awards.

Activity has grown modestly from 1 award in 2022 to 7 in 2024, with 6 awards in 2025 and 7 in 2026 year to date. Combined potential value across all 41 awards is $658 thousand, with $557 thousand obligated (85% realization). The vendor operates exclusively as a prime contractor with no subcontract footprint. All recent awards are firm fixed-price and carry ultimate completion dates; none employ set-asides.
