Our dealers do have a 3-4 hour minimum. All Dealers are certified. We have dealers for Craps, Poker, Blackjack and Roulette. All are completely professional and experienced. Since most of our dealers book months in advance, we do need at least 1 months notice to lock in any dealers needed. For events with 4 + Casino Tables, along with the casino dealers we do suggest a pit boss. We do have pit bosses available as well. Occasionally we can still accommodate on shorter notice, but we cannot guarantee the availability of dealers on short notice. Contact our office directly by calling 720-308-4300 for inquires about dealers for events sooner than 3 weeks out.
