Greenberg Traurig is expanding its litigation practice in Miami with a new shareholder who previously helped lead Pennsylvania-based Buchanan Ingersoll & Rooney’s class action practice.

Before arriving at Greenberg Traurig, A. Sheila Oretsky already had experience representing clients like Twitter and winning disputes like one that got her client a nearly $1 million refund for his downtown Miami condo. Her move comes amid a tightening labor market in Miami’s legal market that shows  no signs of loosening, causing firms to scramble for quality talent.
