The simplest realization of the inverse seesaw mechanism in a $SU(3{)}_C\otimes SU(3{)}_L\otimes U(1{)}_X$ gauge theory offers striking flavor correlations between rare charged lepton flavor violating decays and the measured neutrino oscillations parameters. The predictions follow from the gauge structure itself without the need for any flavor symmetry. Such tight complementarity between charged lepton flavor violation and neutrino oscillations renders the scenario strictly testable.
