Marshfield Clinic, Inc.

Marshfield Clinic, Inc., a non-profit tax-exempt healthcare organization based in Marshfield, Wisconsin, operates as a prime contractor and sub-recipient on federal research and clinical contracts with the Centers for Disease Control and Prevention, Department of Veterans Affairs, and the National Institutes of Health, delivering epidemiological surveillance, vaccine safety monitoring, and clinical research services without set-aside designation. The organization is a subsidiary of parent entity Marshfield Clinic Health System, Inc., the largest integrated rural healthcare system serving Wisconsin and Michigan's Upper Peninsula.

CDC Pittsburgh dominates Marshfield Clinic's customer concentration, accounting for 32 awards valued at $407.7 million in combined potential value—approximately 85% of the vendor's total federal footprint—with work centered on vaccine safety data analysis, Lyme disease surveillance and epidemiology, and serum repository development and maintenance. Representative prime contract examples include a $3.76 million delivery order under the Vaccine Safety Datalink (VSD) master IDIQ issued September 28, 2022, carrying a cost-no-fee structure with ultimate completion September 27, 2027; a $1.23 million definitive contract for serum repository development and maintenance awarded September 22, 2023, through September 24, 2028; and a $603,803 sole-source definitive contract for electronic health record algorithm development supporting the Surveillance Based Lyme Disease Network awarded September 30, 2024, through September 29, 2026. The most recent award is an $1.064 million delivery order from CDC Pittsburgh issued August 23, 2026, to evaluate the childhood vaccination schedule per Executive Order 14398, running through June 30, 2028. The Department of Veterans Affairs contributes 39 awards, though at modest scale; the Department of the Army and National Institute of Allergy and Infectious Diseases round out the active customer set.

Marshfield Clinic holds a position on the Vaccine Safety Datalink (VSD), a $149 million CDC multiple-award indefinite-delivery contract awarded September 20, 2022, through September 19, 2027. The organization has issued or drawn 15 task orders against the VSD master IDIQ, generating $12.4 million in combined potential value. A second major vehicle, an Army indefinite-delivery contract (W912J208A0009), has generated 27 task orders totaling $224 thousand. Activity has grown from nine awards in 2022 to 23 in 2024, though 2025 and 2026 show moderation at 18 and 5 awards respectively, suggesting potential pipeline volatility. Seven awards with combined potential value of $7.4 million face ultimate completion within the next twenty-four months, creating near-term recompete exposure centered on CDC vaccine safety and epidemiological monitoring work.

SCI-reported federal invoicing captures only a narrow slice of Marshfield Clinic's federal activity: $1.6 million invoiced in FY2025 across 7.7 full-time equivalents on SCI-reportable prime service contracts above the $150,000 threshold. Median government-paid hourly rates on those contracts run approximately $137.80 per hour, with senior rates around $138.22 per hour. The organization self-performs work on federal service contracts captured in SCI, with zero sub-hours share across prime records—labor is delivered directly by Marshfield Clinic staff rather than through subcontractors.

Marshfield Clinic operates predominantly as a prime contractor on research and clinical awards, accounting for 68% of recent awards, with a 32% sub-award footprint. As a subcontractor, the organization performs research labor under University of Wisconsin System, Lovelace Biomedical Research Institute, and Kaiser Foundation Health Plan of Washington primes, conducting tasks such as SARS-CoV-2 sequencing data support, EHR data extraction and quality assurance for transfusion-based research under the REDS-IV-P program, and influenza virus typing and genomic sequencing on specimens sourced through the US Flu Vaccine Effectiveness Network.

Federal grant activity covers health research, rural substance-use disorder response, and public health prevention. Marshfield Clinic is a prime grant recipient on awards from the National Institute of Dental and Craniofacial Research (genomic regulatory elements and oral clefts research, awarded August 14, 2025), the Substance Abuse and Mental Health Services Administration Center for Substance Abuse Prevention (Northwoods Prevention and Recovery grant addressing underage drinking and mental health in rural Wisconsin counties, awarded September 30, 2024, through September 29, 2029), the CDC (longitudinal surveillance of exposures and outcomes among pregnant people and infants, awarded September 30, 2023, through September 29, 2027), and the Federal Office of Rural Health Policy (Rural Communities Opioid Response Program–Overdose Response grant, awarded September 1, 2023, through August 31, 2024, with $300 thousand in requested funds). The organization acts as sub-recipient on numerous NIH, CDC, and state health-agency grants routed through University of Wisconsin System, Oregon Health & Science University, and Regents of the University of Minnesota, delivering clinical site coordination, EHR data extraction and analytics, ECHO Cohort Protocol implementation supporting pediatric environmental health research, and rural health workforce training and workforce development.

The vendor's work concentrates in NAICS 621511 (Medical Laboratories, 46 awards) and PSC Reference Laboratory Testing (47 awards), with substantial life-sciences research activity under NAICS 541711 (Research and Development in the Physical, Engineering, and Life Sciences, 9 awards) and PSC R&D–Medical: Other (28 awards). Place of performance spans Marshfield, Wisconsin; Fort Collins, Colorado; and Iowa City, Iowa, depending on contract scope. The organization leverages its integrated healthcare system infrastructure—clinical access, EHR data at scale, patient populations in rural regions, and research institute capability—to anchor federal epidemiological surveillance, vaccine safety monitoring, and health services research partnerships with federal health agencies.
