I will present distances to a sample of over 15 high redshift (0.14 \leq z \leq 0.78) galaxy clusters from a joint analaysis of 30 GHz interferometric Sunyaev-Zel'dovich effect (SZE) data and archival ROSAT X-ray data. These distances are used to place constraints on the Hubble parameter for three different cosmologies. Though dominated by systemaics, they can be addressed with current X-ray satelites (Chandra & XMM-Newton) and radio observatories (OVRO, BIMA, & VLA). We briefly discuss these systematics and their approachable nature.
