In this talk I discuss the qualitative features of an SO(10) SUSY GUT with an SU(2)x U(1)$^n$ family symmetry. I then describe the global fit of this theory to precision electroweak data [including charged fermion masses and mixing angles]. Finally, the predictions of the model for neutrino masses and mixing are discussed. The most predictive version of the model naturally fits atmospheric neutrino data with maximal $\nu_\mu \longrightarrow \nu_\tau$ oscillations and solar neutrino data with small mixing angle MSW $\nu_e \longrightarrow \nu_{sterile}$ oscillations.
