Dark matter remains one of the biggest mysteries in physics, and one way we might detect it is through gamma rays produced when hypothetical Weakly Interacting Massive Particles (WIMPs) annihilate. Dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are some of the best places to look for these signals since they have a lot of inferred dark matter and very little interfering background. In this talk, I describe a major collaborative effort where we combined data from five leading gamma-ray observatories: Fermi-LAT, H.E.S.S., MAGIC, VERITAS, and HAWC. These instruments cover a huge energy range, from 100 MeV to over 10 TeV, giving us a comprehensive look at possible dark matter signatures.
