  We propose a low-scale renormalizable trinification theory that successfully
explains the flavor hierarchies and neutrino puzzle in the Standard Model (SM),
as well as provides a dark matter candidate and also contains the necessary
means for efficient leptogenesis. The proposed theory is based on the
trinification $\SU{3}{C}\times \SU{3}{L}\times \SU{3}{R}$ gauge symmetry, which
is supplemented with an additional flavor symmetry $\U{X}\times Z_{2}^{(1)}
\times Z_{2}^{(2)}$. In the proposed model the top quark and the exotic
fermions acquire tree-level masses, whereas the lighter SM charged fermions
gain masses radiatively at one-loop level. In addition, the light active
neutrino masses arise from a combination of radiative and type-I seesaw
mechanisms, with the Dirac neutrino mass matrix generated at one-loop level.
