We present charmed hadron spectroscopy results from the photoproduction experiment FOCUS (FNAL-E831). We report new, precise measurements of the masses and widths of the $\dmeson_2^{*+}$ and $\dmeson_2^{*0}$ mesons, evidence for the $\dmeson_0^{*+}$ and $\dmeson_0^{*0}$ broad states (the first such evidence in $\dzero \piplus$), and confirmation of the recently observed $\dmeson_s^+(2317)$ charmed-strange state.
