As it has been shown in the literature, triplet extended Higgs sectors suffer from fine tuning issues not present in the usual SM. These problems were solved in the Georgi-Macachek (GM) model by introducing a custodially invariant triplet extended Higgs sector. The quadratic divergences that arise in the corrections to the rho parameter in the GM model disappear when making it supersymmetric. Since the theory is expected to be custodially invariant at the SUSY breaking scale, we discuss how the breaking induced by the top Yukawa coupling and g' will affect the features of this model at the Electroweak scale.
