Stchealth LLC

Stchealth LLC, a for-profit limited liability company based in Phoenix, Arizona, operates as a prime contractor delivering immunization information systems software, platform maintenance, and public health data management technology to the Centers for Disease Control and Prevention. The vendor competes in full-and-open federal procurement with no SBA set-aside designations across its prime footprint.

Stchealth's capability portfolio centers on proprietary immunization information system (IIS) software platforms, vaccine data connectivity infrastructure, disease surveillance systems, and technical services supporting multi-jurisdictional vaccine tracking and reporting. Representative prime work includes a $13.4 million delivery order from CDC Pittsburgh (September 2026) for Immunization Information Systems Technology Services running through September 2029; a $19 million delivery order under the Immunization Information Services IDIQ (September 2024) for immunization tracking and public health data management; a $5.9 million delivery order (September 2023) under GSA Multiple Award Schedule for the West Virginia Immunization Information System; an $8.97 million delivery order (July 2023) for immunization systems maintenance and service; and a $13.24 million sole-source definitive contract (August 2022) for connecting IIS products to the Immunization Gateway and CDC for data reporting. CDC Pittsburgh justified the 2022 sole-source award on the grounds that Stchealth provides the proprietary IIS software required for performance.

Customer concentration is extreme. CDC Pittsburgh accounts for 25 awards carrying $1.3 billion in combined potential value — 95% of the vendor's total federal award volume of $1.37 billion. The remaining customer base includes GSA Federal Acquisition Service ($46.7 million across 2 awards), CDC Office of Acquisition Services ($6 million across 12 awards), and departmental HHS ($5.6 million across 10 awards). The top-five customer agencies, spanning CDC components and GSA, cover 70% of recent awards and 99% of combined potential value. Stchealth holds a single-award Indefinite Delivery Contract with CDC Pittsburgh for Immunization Information Services, awarded September 2024 with a $90 million ceiling and completion date of September 2029; this IDIQ anchors the vendor's largest vehicles. The vendor also places work under GSA Multiple Award Schedule (36 task orders, $1.07 billion combined potential value), Federal Supply Schedule GS35F0081L (19 task orders, $9.3 million), and IT Schedule 70 (5 task orders, $7 million).

Activity trajectory is irregular. The vendor recorded one award in 2022, four in 2023, four in 2024, one in 2025, and one in 2026 (the September 2026 CDC delivery order). Only one award ($5.9 million potential value) has an ultimate completion date within the next twenty-four months, indicating low near-term recompete pressure and sustained contract coverage through mid-2029 under the newly awarded CDC IDIQ.

Service Contract Inventory data shows Stchealth invoiced $4.5 million in FY2022 across 51.2 FTEs and $9.9 million in FY2024 across 69.7 FTEs. No SCI records appear for FY2023 or FY2025, consistent with procurement cycles. Across SCI-reportable prime contracts, government-paid hourly rates span $22.24 per hour at the tenth percentile through $147.48 per hour at the ninety-percentile, with a median of $44.72 per hour, reflecting a mixed labor mix from entry-level data support through senior technical architects. Stchealth self-performs all reported labor on SCI-reportable contracts with zero subcontractor engagement, a pattern reflected in the vendor's 90% prime-to-sub split across the full award portfolio. Stchealth also acts as a sub-recipient under federal grants, including immunization and vaccine-preventable-disease strengthening programs under the Indiana Department of Health and Tennessee Department of Health (five sub-awards, FY2023–FY2025).
