We study the lepton flavor violating mu(-) -> e(-)2 gamma decay induced by the mediation of heavy leptons, such as the excited and fourth generation leptons. Effects of these leptons in mu(-) -> e(-)2 gamma decay are examined. It is found that the branching ratio of this decay is very sensitive to excited and fourth generation leptons. Furthermore, we obtain the bounds on model parameters by using the current experimental limit of this decay.
