We determine the dynamical black hole mass in NGC404 including modeling of the nuclear stellar populations. We combine \hst/STIS spectroscopy with WFC3 images to create a local color-\ml~relation derived from stellar population modeling of the STIS data. We then use this to create a mass model for the nuclear region. We use Jeans modeling to fit this mass model to adaptive optics stellar kinematic observations from Gemini/NIFS. From our stellar dynamical modeling, we find a 3$\sigma$ upper limit on the black hole mass of $1.5\times10^5$\Msun.
