Our Story

Built on Honest Work

Rocky Mountain Auto Works was founded by Eli Brennan after 14 years working in a flat-rate franchise mill where techs were paid to upsell, not to fix. Tired of telling customers their car needed work it didn't need, Eli opened his own shop in 2006 with one rule: every repair gets diagnosed before it gets quoted, and every quote is the price you pay. Nineteen years and 412 five-star reviews later, that rule hasn't changed.
