We design a supersymmetric SU(5) grand unified theory model using {Delta}(54), a finite non-Abelian subgroup of SU(3){sub f}. Heavy right-handed neutrinos are introduced which transform as a three-dimensional representation of our chosen family group. The model successfully reproduces the hierarchical structures of the standard model and the Cabibbo-Kobayashi-Maskawa mixing matrix. It then provides predictions for the light neutrinos with a normal hierarchy and masses such that m{sub {nu}},1{approx_equal}5x10{sup -3} eV, m{sub {nu}},2{approx_equal}1x10{sup -2} eV, and m{sub {nu}},3{approx_equal}5x10{sup -2} eV. We also provide predictions for masses of the heavy neutrinos, and corrections to the tribimaximal matrix that fit within experimental limits, e.g., a reactor angle of -7.31 deg. A simple modification to our model is introduced at the end and is shown to also produce predictions that fall well within those limits.
