Trauma Advisory Committee

Membership and Meetings

Since 1992, the Trauma Advisory Committee (TAC) has developed an organized System of trauma care to reduce morbidity and mortality from the most serious injuries and assure equally appropriate care for all other injuries. Meetings are held quarterly on the 4th Tuesday in the months of January, April, July and October at 12:30 PM.

All meetings are open to the public, with the exception of those portions that may be conducted in executive session in accordance with Maine Law 32 M.R.S.A. § 90-A(3) and 1 M.R.S.A. § 405(6)(E) & (F)

All meetings are held at Maine EMS, 45 Commerce Drive, Suite 1, Augusta, ME 04333.  Meetings are typically held in the Champlain conference room.  Directions are located here.


A variety of resources related to the Maine EMS trauma system can be found here.
