SAN FRANCISCO — Three women, all partners at DLA Piper, have broken out of Big Law to found a firm of their own.

Litigators Luanne Sacks and Cynthia Ricketts and employment partner Hope Case struck out about two weeks ago to launch Sacks, Ricketts & Case. With offices in San Francisco, Palo Alto and Phoenix, the firm will focus on consumer and employment class actions, employment counseling and commercial litigation. The firm counts eight lawyers, seven of whom came straight from DLA Piper, and expects to add another partner in mid-July.
