The SDSS-III MARVELS survey is a comprehensive radial velocity survey of 10,000 nearby F through K stars, between magnitudes 7.6 < V < 12.0. The primary goal of this survey is to search for planets among a homogeneous set of stars, which will be used to put constraints on formation and evolution models. This survey is also very sensitive to more massive companions such as brown dwarfs (BDs) and low mass binaries. We will discuss an ongoing project aimed at characterizing the properties of these massive companions. As part of the first two years of the six year MARVELS project, approximately 2,000 stars were searched for BDs from 1 to 180 days using a modified Lomb-Scargle periodogram, yielding roughly a dozen candidates. The completeness of this BD dataset will be determined from Monte Carlo simulations, and the completeness corrected dataset will be used to compute the fraction of solar-like stars that host short- to intermediate-period BD companions. Several of these BD have host stars characterized allowing us to explore in detail their place in the BD desert and how parameters like spectral type and metallicity play a role. Finally, this large homegeneous radial velocity survey will be placed in the larger context of our current knowledge about BD statistics.
