We discuss the structure of the neutrino mass matrix as derived from a nonuniversal electroweak gauge interaction model. We discuss two interesting patterns of neutrino masses. The first pattern is hierarchal which fits the large mixing angle or low probability, low mass solution of solar neutrino data. The second pattern gives rise to an inverted mass spectrum which fits the currently not preferred small mixing angle solution. The mechanism for generating a light sterile neutrino mass is interesting and is briefly discussed.
