In this paper, we realize the tri-bimaximal mixing in the lepton sector inthe context of minimal seesaw in which only two right-handed neutrinos areintroduced, with the discrete group $S4$ as the family symmetry. In order toconstrain the form of superpotential, a $Z3$ symmetry is also introduced. Inthe model, the mass matrices for charged leptons and right-handed neutrinos arediagonal. The unitary matrix that diagonalizes the light Majorana neutrino massmatrix is exact tri-bimaximal at LO, and is corrected by small quantities of$\mathcal{O}(0.01)$ at NLO. The mechanism to get the particular scalar VEValignments used is also presented. Phenomenologically, the mass spectrum is ofnormal hierarchy with $m_1=0$, and $\sum m_i$ and $|m_{ee}|$ are about $0.058eV$ and $0.003 eV$ respectively.
