Founder Tara Koestner started Treasure State Hospitality with a simple idea: gatherings should be seamless, memorable, and stress-free. Having worked across every corner of the hospitality industry, Tara saw how much clients value not just great drinks, but a dependable partner who can handle the details behind the scenes. That vision turned into a company that now serves weddings, parties, and corporate events across Northwest Montana.

We’re more than bartenders—we’re full-service event partners. From licensed bar service and mobile saloon trailers to rentals, coordination, and even our very own event venue (The Patio in Whitefish), we cover every detail so you can focus on making memories.
