In the supersymmetric seesaw model of neutrino masses, augmented by the non-Abelian discrete tetrahedral symmetry ${A}_{4}$, a specific pattern of neutrino mixing is automatically generated if one of the three heavy singlet neutrino superfields acquires a nonzero vacuum expectation value. This pattern turns out to be exactly that of tribimaximal mixing, i.e. ${sin}^{2}{\ensuremath{\theta}}_{23}=1/2$, ${sin}^{2}{\ensuremath{\theta}}_{12}=1/3$, and ${sin}^{2}{\ensuremath{\theta}}_{13}=0$, in good agreement with data.
