We used multi-color timeseries photometry carried out in SDSS Stripe 82 over a baseline of nearly 10 years to identify a sample of 30 M-dwarf eclipsing binary candidates. Estimates of these objects' periods were generated using this sparsely sampled data, and targets for photometric followup campaigns were identified. We have recently observed five of these candidates with the KPNO 2.1-m telescope and obtained well-sampled light-curves of these objects' primary and secondary eclipses. Our targets have short periods (< 1.0 day) and have spectral types ranging from M1 to M4. Here, we present results of modeling these objects' light-curves and initial estimates of their relative radii, temperatures, luminosities, orbital inclination, and finally, improved periods and ephemerides. These observations, combined with measurements of radial velocities, will result in estimates of stellar masses and radii for the low mass components of these systems.
