WILLIAM H. NUESSE, M.D. AND MARY ANN NUESSE, D.O., A MEDICAL CORPORATION

William H. Nuesse, M.D. and Mary Ann Nuesse, D.O., A Medical Corporation provides clinical medical services under a physician practice structure, specializing in civilian medical surveillance and operational health support for federal entities. Their core capabilities center on delivering direct patient care, occupational health monitoring, and medical oversight in non-clinical, mission-critical environments—particularly within defense-affiliated settings such as civilian fire departments. The contractor’s technical expertise includes medical readiness assessments, workplace health surveillance, and compliance with federal occupational health standards, with a focus on preventive medicine and longitudinal health data collection for high-risk personnel. Their differentiation lies in integrated physician-led surveillance protocols that bridge clinical practice with federal operational requirements, ensuring alignment with DoD and public safety health mandates. The contractor has demonstrated direct engagement with the Department of Defense, providing medical surveillance services tailored to civilian first responder populations. This relationship reflects a niche specialization in supporting non-military personnel operating under federal operational frameworks, where medical monitoring is essential to mission sustainability and regulatory compliance. Their primary industry focus is on physician office services (NAICS 621111), specifically in contexts requiring government-contracted clinical oversight beyond traditional outpatient care. This positions them within the federal support services market as a provider of embedded, mission-critical medical functions rather than general practice care. The entity is structured as a closely held medical corporation (2L) based in Orange, California, with no federal certifications on record. While small in scale, their geographic presence and specialized service model enable targeted participation in defense and public safety health programs, serving as a trusted provider of physician-led medical surveillance in federal operational environments.
