Formed in 1995 by Chris Ross (drums), Walt Svekla (bass), and John Fraumberger (guitar) who enlisted the help of Sick Of It All roadie, Tim Shaw on vocals.

By 1997 had Svekla stepped aside and Nate Gluck (Strength 691, Vision) filled in on bass. Shortly after that, Chris Ross left the band as well and was replaced by Seattle transplant Ryan Murphy (Undertow, Ten Yard Fight).
The last original founding member of Ensign, John Fraumberger, quit the band that year as well. He left the band so that he could pursue his teaching degree and so now once again, a member change. Stepping up to take John's place on the endless amount of touring that they had to look forward to was Ensign fan and friend, Ryan "Mackenzie" Donoghue.

Members of the band remain active at Blackout! Records, The Fire Still Burns and the band itself is still working on new material for their upcoming 2006 full length.
