Westchester Emergency Medical Services

What Westchester Emergency Medical Services does

Westchester Emergency Medical Services (WEMS), legally Starnet Emergency Services d/b/a Westchester EMS, is a 501(c)(3) nonprofit emergency medical services provider founded in 2000 under the Stellaris Health Network, a four-hospital system in Westchester County, New York. Headquartered in Mount Kisco, WEMS delivers 911 emergency response, non-emergency medical transport, paramedic fly-car coverage, event standby medical services, and contracted EMT staffing to fire districts and healthcare facilities across approximately 235 square miles of northeastern Westchester County, serving roughly 144,000 residents, with capability for tri-state and East Coast long-distance medical transports.

WEMS operates two primary franchise footprints: the Northern Westchester / 45 Medics operation covering ~200 square miles and ~100,000 residents with 7,000+ calls per year, and the Town of Mount Pleasant / 37 Medics operation covering ~35 square miles and ~44,000 residents with ~4,000 calls per year. The clinical technology stack includes LP15 monitors, LUCAS CPR devices, Hamilton T1 ventilators, video laryngoscopes, Baxter IV pumps, Stryker PowerCot Pro stretchers, and Stryker PowerLoad systems, mounted on Chevy Tahoe PPV fly cars; dispatch is handled through a Zoll-based system. Revenue-cycle operations are supported by AGS Global Solutions (medical billing) and Patient Notebook (patient payments).

The business model combines five revenue streams: medical transport billing across insurance, Medicare, and Medicaid; healthcare facility contracts (anchored by Stellaris hospitals); 911 emergency response franchise agreements; event standby medical services; and EMT staffing contracts with municipal fire and EMS organizations including the Somers Fire District (since 2010), Armonk Fire Department (since 2014), and North Salem Volunteer Ambulance Corps (since 2016).

Direct peers

• Empress EMS: Empress is a New York-area private ambulance provider offering 911 response, BLS/ALS transport, critical care, and event standby. Its regional NY focus and similar service mix make it a direct functional peer to WEMS in the tri-state EMS market.
• American Medical Response (AMR): AMR is the largest private ambulance and EMS provider in the United States, offering BLS, ALS, critical care transport, and 911 response. It is a directly comparable private EMS operator with overlapping service lines including specialty transport, mutual aid, and contracted municipal coverage.
• Falck USA: Falck is a global EMS and ambulance services provider with U.S. operations delivering 911 response, interfacility transport, and specialized medical services. Its private EMS model, 911 contract footprint, and specialty transport capabilities map closely to WEMS's core service structure.
• MTR Ambulance: MTR is a New York-area private EMS provider offering emergency and non-emergency ambulance transport, BLS/ALS services, and event coverage across the metro region. It is a direct functional peer in terms of services offered, customer mix, and operating geography.
• Liberty Ambulance: Liberty Ambulance is a privately operated New Jersey and tri-state area ambulance service delivering BLS, ALS, critical care, and wheelchair transport. Its service scope and tri-state operating geography overlap meaningfully with WEMS's interfacility and tri-state long-distance transport offerings.
• TransCare Ambulance: TransCare is a New York-area private ambulance operator providing 911 response, BLS, ALS, and critical care transport. It is comparable in scale and service mix to WEMS and competes for the same NY metro hospital transport and municipal contract demand.

Broad incumbents

• Northwell Health EMS: Northwell operates the largest hospital-based EMS system in New York, providing 911 response, interfacility transport, and specialty care across the NY metro. It is a broader-scale, hospital-affiliated incumbent competing for the same Westchester-area inter-facility volume that WEMS serves.
• Mount Sinai Health System: Mount Sinai operates hospital-affiliated EMS and patient transport services through its NY metro hospitals. As a large health system with internal transport capabilities, it represents a broader incumbent that competes indirectly with WEMS for inter-facility and specialty referral volume.
