The Milky Way's satellite galaxies provide critical clues to how low mass galaxies form and the nature of dark matter. Yet the Milky Way itself is a single realization of a Milky Way-mass galaxy halo. I will present the main findings of the Satellites Around Galactic Analogs (SAGA) Survey, a spectroscopic survey characterizing satellite galaxies around Milky Way-mass galaxies. The SAGA Survey includes 378 satellites identified across 101 systems. I will discuss SAGA Survey results on the quenched fraction of satellites, luminosity functions, radial distributions, star-formation properties and more.
