The discovery of neutrino oscillations in the late 1990s demonstrated that the neutrinos have mass.  But we still know very little about the absolute scale of the neutrino mass.  In the laboratory, one can probe the neutrino mass scale either by studying the $\beta$-decay of certain favorable nuclei (e.g. those decay by superallowed transitions) or by searching for neutrinoless $\beta\beta$ decays in certain even-even nuclei.  While the former is a model-independent kinemetic measurement, the latter is dependent on the specific model that allows a lepton-number violating process to proceed.  In this talk, how these measurements will enhance our knowledge of the neutrino mass scale will be reviewed.
