What believers are saying

  • Texas operations grew by acquisition: Marksman bought Austin's Priebe Security Services in January 2026, adding over 450 employees.
  • Frontline hires reach leadership: Marksman's Las Vegas vice president started as a guard in 2013, then earned five promotions.
  • Part-timers earn paid time off: Marksman's Buckhead, Atlanta officer posting grants eight hours for every 100 worked.

What critics are saying

  • Officer pay is modest: Marksman's part-time Mesquite, Texas retail officer posting pays $15.84 an hour.
  • Flex schedules are unpredictable: Marksman's Plano, Texas flex officer posting requires answering assignments with little to no notice.
