In conventional models of gauge-mediated supersymmetry breaking, the lightest supersymmetric particle is invariably the gravitino. However, if the supersymmetry-breaking sector is strongly coupled, conformal sequestering may raise the mass of the gravitino relative to the remaining soft supersymmetry-breaking masses. In this paper, we demonstrate that such conformal dynamics in gauge-mediated theories may give rise to satisfactory neutralino dark matter while simultaneously solving the flavor and {mu}/B{mu} problems.
