  We explore the collider signatures of the Higgs sectors in singlet-extended
MSSM models. We find that even with reduced couplings due to singlet mixing, a
significant portion of the parameter spaces have a discoverable Higgs via
traditional decay modes or via invisible decays (directly to neutralinos or
through cascade decays to neutralinos and neutrinos). For illustrative points
in parameter space we give the likelihood of Higgs discovery. In cases where
neither traditional nor invisible modes can discover the Higgs, the neutralino
sector may provide evidence for the extended models.
