Known affectionately as "the Gaymber," the Tucson LGBT Chamber of Commerce connects LGBTQIA+ and allied business professionals across Southern Arizona through networking, education, and advocacy. Originally formed in the early 1990s as a private support network, it grew into a formal 501(c)(6) organization and later added a companion foundation that awards scholarships to University of Arizona students. The chamber works to elevate queer-owned businesses and voices throughout the community.
