Galaxy clusters are among the most sensitive dark energy probes, but their utility will be increasingly limited by systematic uncertainty in cluster mass estimation. The use of multi-wavelength cluster data is one way to mitigate this limitation. Such a combination will be possible due to significant overlap of current and near-future cluster surveys, particularly the South Pole Telescope (SPT) and the Dark Energy Survey (DES). I present the results of a pilot study that simultaneously uses optical data from the Sloan Digital Sky Survey and Sunyaev-Zel'dovich observations from CARMA to improve our understanding of joint cluster scaling relations. The results from this work will inform cosmological analyses of SPT+DES cluster samples.
