Founded in 1978 by Montana native Gary Treweek, Treweek Mini Storage began with just 10 storage units. After growing to accommodate the development of Greater Flathead Valley, the self-storage now features over 300 units, including personalized services. Whether you just need to keep a few boxes or require boat storage, you'll find the perfect size unit for you. The easy access and high security of this center are ideal for anyone who needs long-term storage. Addition to this, to make moving easier, we sell some moving supplies inside too.
