To most thoroughly understand exoplanetary systems, in both individual and statistical senses, requires a thorough characterization of their host stars. Whether or not a host star has companions, and the properties of those companions, directly affects the measured radii of transiting exoplanets. How active or jittery a host star is dictates the precision and accuracy with which we can measure the masses of orbiting planets. And recent work is showing how host star composition serves as an important piece of the exoplanet composition puzzle. In this talk I will discuss how I am using high resolution imaging and spectroscopic studies of host stars to investigate the properties and diversity of exoplanets in the Galaxy.
