The SPT-SZ is, currently, the most powerful instrument for detecting galaxy clusters through the Sunyaev-Zel'dovich (SZ) effect. The SPT-SZ focal plane consists of over 700 background limited TES spiderweb bolometers observing in three different pass bands (90 GHz, 150 GHz, and 220 GHz) readout by a frequency domain SQUID multiplexer. Together with the 10-m South Pole Telescope, SPT-SZ has realized exceptional sensitivity at arcminute resolution over a one degree field of view and is the first instrument to discover new galaxy clusters through the SZ effect. We will discuss the SPT-SZ design and deployment, present initial results from the first two seasons, and outline future survey plans.
