The Ohio 1 Disaster Medical Assistance Team (OH-1 DMAT) is a Federal response unit made up of highly trained health care professionals and support personnel. The  mission of OH-1 is to provide compassionate medical care to victims of disasters (natural or man made) as a part of the unified response component of the National Response Plan. The team, originally organized in 1985,  has been formally a foundational component of the National Disaster Medical System (NDMS) since 1990. The members of the OH-1 DMAT have a long and distinguished history of service to our country.

Once having met Federal employment criteria, team members are then classified as part time, intermittent federal appointment employees of the Department of Health and Human Services and are called to active duty when situations require the specialized services of the team.  Our team  members come from communities in North Central and North Eastern OH, Northern IN, South Eastern MI and North East IL. Composed of approximately 150 personnel, we maintain a “Ready” state of preparedness  and remain in a “go-team” posture  24/7/365.
