I will discuss a class of multi-Higgs doublet extensions of the Standard Model that solves the strong CP problem with profound consequences for the flavor sector. A flavor symmetry, G, that acts on Higgs and quark fields is a key feature of these theories. CP and G are only softly broken in the scalar potential, so that for certain choices of G charges, the strong CP parameter is zero at tree-level. I will then discuss radiative corrections in this class of theories, as well as the contribution from higher-dimensional operators and the connections with the hierarchies observed in quark masses and mixing angles.
