Authority dates

Common carrier authority status: Inactive
Broker authority on record since: December 8, 2021 (original grant date not in FMCSA's electronic records)

From FMCSA's authority history (its current Motus system, plus the older L&I history it froze on May 14, 2026). "First granted" is the earliest grant on record; "on record since" is the earliest action FMCSA has when the grant itself is older than its electronic records. "Active since" is the latest grant or reinstatement, so a lapse that FMCSA reinstated restarts the clock.
