Polsinelli, a national law firm, has announced the opening of a new office in Philadelphia. This expansion comes after the firm hired more than 20 partners, including shareholders, from Holland & Knight. The new hires will bolster Polsinelli's practices in corporate, litigation, employee benefits, and executive compensation. This move follows Polsinelli's recent office openings in Fort Worth, Texas, and Park City, Utah. The departure of these partners has led Holland & Knight to reconsider the future of its Philadelphia office. Polsinelli touts a 'meteoric rise' in revenue ranking with these additions.
