In this thesis, we consider a supersymmetrized version of the Standard Model extended with a technicolor sector. We specialize in the regime of the model in which the technicolor sector is fully responsible of the electroweak symmetry breaking and the natural elementary Higgses of the supersymmetric model only transmit the breaking to the Standard Model fermions, thereby giving them masses. In particular, we consider the vacuum structure of the effective theory, find it to be different to that of a mere technicolor model and study the contributions of the new sector to the oblique electroweak parameters. Relative to the current experimental limits, we find the model viable.
