  We construct a supersymmetric $S_4$ flavor symmetry model with one of the
trimaximal neutrino mixing patterns, the so-called TM$_1$, by using the novel
way to stabilize flavons, which we proposed recently. The flavons are assumed
to have tachyonic supersymmetry breaking mass terms and stabilized by
higher-dimensional terms in the potential. We can obtain the desired alignment
structure of the flavon vacuum expectation values to realize neutrino masses
and mixings consistent with the current observations. This mechanism naturally
avoids the appearance of dangerous cosmological domain walls.
