We find the parameters of the MSSM in terms of bulk supergravity fields for the D-brane model of Berenstein, Jejjala, and Leigh. The model consists of a D3-brane at the singularity of a non-Abelian orbifold Delta(27), which gives the particles of the supersymmetric standard model. We compute the action for the D-brane fields in the presence of both supersymmetric and supersymmetry breaking background fluxes. We get quark, lepton, gaugino, Higgsino, scalar partners and Higgs boson masses as well as soft trilinear couplings as functions of the background fields. This work develops a framework for connecting MSSM phenomenology to brane compactifications.
