Idaho Theta Province was installed September 6, 2025. There are 5 Chapters in the Treasure Valley and more will be added. We are looking for new Sisters ready to join our new Meridian Chapter and our Nampa/Caldwell Chapter.
Sigma Phi Gamma is the embodiment of real sisterhood in practical ways. Getting together through fun social activities and working together in areas of service we are passionate about creates the tangible connection that makes authentic sisterhood take shape.
Join us to find that sense of belonging while creating lifelong friendships and serving the community in meaningful and impactful ways.
