Abstract: D-brane constructions of the Standard Model are often carried out in a local setting; the branes are at singularities or wrap local cycles. Isometries in the local geometry imply global symmetries in the model.  In this talk, we will discuss the size and form of the leading symmetry breaking effects once such models are embedded into a compactification. The setting allows for hierarchical separation in the symmetry breaking parameters.
