V838 Monocerotis is an eruptive variable which gained notoriety in 2002 when it brightened by 9 magnitudes in a series of outbursts, and eventually developed a spectacular light echo. The star's mid-IR flux increased by a factor of 2 between 2004 and 2007, suggesting that new dust was condensing from the expanding ejecta of the outbursts, while more recent optical spectroscopic observations suggest that these expanding ejecta have engulfed the system's B3V binary companion. We present new optical, near-IR, and mid-IR spectroscopic and mid-IR photometric observations of V838 Monocerotis obtained between 2008-2009 at the Apache Point Observatory 3.5m, NASA IRTF 3m, and Gemini South 8m telescopes. We discuss the chemistry and continued evolution of recently formed dust in the system in the context of previously published photometric, spectroscopic, and spectro-polarimetric observations of the system.
