We analyze the lepton sector of the left-right twin Higgs model. This model offers an alternative way to solve the 'little hierarchy' problem of the standard model. We show that one can achieve an effective seesaw to explain the origin of neutrino masses and that this model can accommodate the observed neutrino masses and mixings. We have also studied the lepton flavor violation process l{sub i}{yields}l{sub j}{gamma} and discussed how the experimental bound from these branching ratios constrains the scale of symmetry breaking of this twin Higgs model.
