Abstract: The charmonium system provides an opportunity to explore a wide variety of topics in hadronic physics. Studies of the properties of and transitions among cc-bar states yield insight into relativistic and non-perturbative QCD effects. At the same time, studies of the decays of charmonium states are a window into gluon dynamics and the role of glueball mixing in the production of light quark states. A collection of preliminary results utilizing the full CLEO-c psi(2S) data sample is presented including two-body branching fractions of chi_cJ decays, a precision measurement of the h_c mass, and results on the hindered M1 transition: psi(2S) -> gamma eta_c.
