We consider the supersymmetric seesaw mechanism induced by the exchange of heavy SU(2)W triplet states, rather than ``right-handed'' neutrino singlets, to generate neutrino masses. We show that in this scenario the neutrino flavor structure tested at low-energy in the atmospheric and solar neutrino experiments is directly inherited from the neutrino Yukawa couplings to the triplets. This allows us to predict the ratio of the \stackrel\ensuremath→\ensuremathτ\ensuremathμ\ensuremathγ (or \stackrel\ensuremath→\ensuremathτe\ensuremathγ) and \stackrel\ensuremath→\ensuremathμe\ensuremathγ decay rates in terms of the low-energy neutrino parameters. Moreover, once the model is embedded in a grand unified model, quark-flavor violation can be linked to lepton-flavor violation.
