We consider the Minimal Gauge Mediated Model (MGMM) with either fundamental or antisymmetric messenger multiplets and study consequences of messenger-matter mixing. We find that in these models, unlike MGMM without mixing, wide range of tanβ is allowed. It is shown that existing experimental limits on processes with lepton flavor violation, and on K0-K0, D0-D0 and B0-B0 - mixing place significant constraints on relevant coupling constants and mixing parameters. On the other hand, the contributions of the messenger-matter mixing to the rates of τ→ eγ, τ→ μγ and b→ sγ may be well below the present experimental limits depending on the value of tanβ. We also point out the possibility of sizeable slepton oscillations in this model.
