This work proposes a neutrino mass model that is derived using the minimal seesaw mechanism which contains only two right-handed neutrinos, under the non-abelian discrete flavor symmetry $\mathbb{ S}_4\otimes\mathbb{ Z}_2$. Two standard model doublets, $L_\mu$ and $L_\tau$, are assigned simultaneously to a $\mathbf{ 2}$ representation of $\mathbb{ S}_4$. When the scalar fields introduced in this model, addition to the Standard Model Higgs, and the leptons are coupled within the symmetry, the seesaw mechanism results in the tri-bi-maximal neutrino mixing. This study examined the possible deviations from TBM mixing related to the experimental data.
