Tri-Hospital EMS Service Area

Tri-Hospital EMS was established in 1983 to provide ambulance service to portions of St. Clair and Sanilac Counties. Twenty-five years later, Tri-Hospital EMS is the largest ambulance provider in St. Clair County, providing service to over 140,000 individuals in a 650 square miles radius, and responding to more than 12,000 runs annually.

Tri Hospital EMS has the privilege to work in conjunction with numerous St. Clair County Fire Services. The majority of these services operate as ‘First Responders’ and may also be dispatched to your request for Emergency Care.

While Tri-Hospital EMS has stations throughout the community, if you have an emergency please do not respond to one of the stations. The stations are not guaranteed to be manned 24-hours-per-day, as we may be providing care to others.

In the case of an emergency, please immediately call 911 and stay at that location until help arrives.

Our Central location houses our Administrative Services, Business and Billing Office, and the Education Department.* Normal business hours for these departments are Monday through Friday from 8:00am – 4:30pm.

* Please note: If you have an education need, contact our department prior to coming as department staff may be teaching off site and not immediately available to address your need.
