We discuss the sparticle (and Higgs) spectrum in a class of flavor symmetry-based minimal supersymmetric standard models, referred to here as sMSSM. In this framework the supersymmetry breaking Lagrangian takes the most general form consistent with a grand unified symmetry such as $SO(10)$ and a non-Abelian flavor symmetry acting on the three families with either a $\mathbf{2}\mathbf{+}\mathbf{1}$ or a $\mathbf{3}$ family assignment. Models based on gauged $SU(2)$ and $SO(3)$ flavor symmetry, as well as non-Abelian discrete symmetries such as $S_3$ and $A_4$, have been suggested which fall into this category. These models describe supersymmetry breaking in terms of seven phenomenological parameters. The soft supersymmetry breaking masses at $M_{\mathrm{GUT}}$ of all sfermions of the first two families are equal in sMSSM, which differ in general from the corresponding third family mass. In such a framework we show that the muon $g-2$ anomaly, the observed Higgs boson mass of $\sim 125\mathrm{GeV}$, and the observed relic neutralino dark matter abundance can be simultaneously accommodated. The resolution of the muon $g-2$ anomaly in particular yields the result that the first two generation squark masses, as well the gluino mass, should be $\lesssim 2\mathrm{TeV}$, which will be tested at LHC14.
