Prosperity Grange was founded in 1910 as a community hub with social, charitable, and community support as its goals. We are affiliated with the Washington State Grange and the national Grange. We have a beautiful Grange hall which is suitable for all kinds of community and social events at a reasonable rental rate. Active members rent for less. Our monthly meeting is 7:00 to 8:00 PM on the first Wednesday of every month except July and August.
