Cozen O’Connor has picked up California’s Miller Law Group, one of the larger woman-owned employment law firms, to add 13 lawyers to its San Francisco and Los Angeles offices.

The consolidation bolsters Cozen O’Connor’s labor and employment practice, and adds seven women lawyers.

“A key element of our strategic plan remains growing our Labor & Employment Department nationally and, as part of our recent commitment to Mansfield 3.0 certification, continuing to diversify our leadership ranks and talent pipeline,” Michael J. Heller, Cozen O’Connor’s executive chairman and CEO, said in a statement.

While Miller Law Group had a broad array of clients to counsel about California employment law— ranging from Fortune 50 corporations to startups— founder Michele Ballard Miller said joining with Cozen O’Connor stemmed from the need to serve clients who had facilities in different locations.

“In order to meet these broader needs, we recognized that we needed to change. Cozen O’Connor was the obvious choice,” she noted in a statement.

She said linking up with Cozen O’Connor “gives our clients access to professionals who can advise on the full complement of employment issues, including immigration and OSHA and employee benefits.”

She also noted that Cozen O’Connor’s commitment to diversity and inclusion was also a key factor in the decision to join up.

“Miller Law Group is certified women-owned and active in many organizations that are committed to achieving diversity and inclusion in the legal profession. Cozen O’Connor’s commitment to this important issue, coupled with the myriad of programs they have instituted in furtherance of this goal, best reflected our core values,” she said.

In May, Cozen O’Connor, with more than 750 lawyers, signed onto the Mansfield rule certification initiative, which requires a firm to consider at least 30 percent of women and other diverse lawyers for hiring and promotion along with other commitments to broaden the diversity of its lawyer ranks.

Cozen O’Connor has 29 offices, including in Seattle, Las Vegas, San Francisco, Los Angeles and San Diego. Two years ago, the firm expanded its West Coast presence when it hired all the lawyers working at Gilchrist and Rutter, a real estate and commercial litigation firm, and opened a Santa Monica outpost.

Miller joins Cozen as a shareholder and chair of the firm’s West Coast Labor & Employment Practice.
