For the first time ever, Law360 has ranked the 100 best U.S. law firms for women, based on the firm’s female representation at the partner and nonpartner levels and its total number of female attorneys.

Almost all of these firms buck the sobering findings of Law360’s 2015 Glass Ceiling Report, which found that just 33 percent of all attorneys — and a scant 22 percent of partners — at U.S. law firms are women. At many of these 100 firms, there are more female nonpartners than male, a rich potential pipeline of future female equity partners and executive committee members.

Leading the pack are Westlake Village, California-based Adelson Testan Novell Brundo & Jimenez and New York-based immigration boutique Fragomen, Del Rey, Bernsen & Loewy LLP. At both firms, more than 54 percent of nonpartners, 49 percent of partners and 40 percent of equity partners are women. 
 

Methodology: Law360 surveyed 308 U.S. firms, or vereins with a U.S. component, about their overall and female head count numbers as of Dec. 31, 2014. Only U.S.-based attorneys were included in the survey. Firms are ranked based on four factors: 1) the percentage of partners, both equity and nonequity, who are women; 2) the percentage of nonpartners who are women; 3) the split between the firm’s female partner percentage and female nonpartner percentage; and 4) the number of female attorneys at the firm.
