Mintz, Levin, Cohn, Ferris, Glovsky and Popeo is picking up new partners on both coasts, including from a San Francisco boutique that is shutting down with the move.

Stephen Osborn will join Mintz's San Francisco office, leaving the firm he co-founded, Osborn McDerby, to close its doors. In Boston, meanwhile, Joshua Fox is joining from Wilmer Cutler Pickering Hale and Dorr.

Osborn and Fox are the latest hires in Mintz's growing corporate practice, which also had two notable hires in March. The Boston-based firm is enjoying record revenue and profit highs after four straight years of growth.

“The addition of Josh and Steve further strengthens the firm in areas of strategic importance to our clients,” said Mintz's managing member, Bob Bodian. “Each attorney brings with them exceptional skills and impressive professional experience. We are delighted to have them join us.”

Osborn founded Osborn McDerby with Rich McDerby in 2012. His exodus marks the end for the boutique law firm, and he said all of his clients, including health and technology companies Partner Fund Management, Varex Imaging, Telegraph Hill Partners and Turing Enterprises, are moving with him to Mintz.

He said that the experience of starting his own firm and building his client base was gratifying but that he wanted more institutional support for his practice and clients.

“This allows me to look at clients from a more holistic perspective and bring in more partners to help with other aspects of their needs,” Osborn said about his move to Mintz. “This will make it feel like more of a team rather than a series of individual advisers.”

McDerby could not be reached for comment.

Prior to starting his own firm, Osborn worked in-house at a health care IT company and at Baker & McKenzie.

Fox spent 18 years at Wilmer, and he focused his practice on advising startups in the technology, medical and biomedical industries. He said he expected most or all of his clients, which include Aquinnah Pharmaceuticals, CozyKin, Asimov and PanTher Therapeutics, to move with him to Mintz.

Fox said he was eager to be joining Mintz because the firm placed such an emphasis on growing its corporate practice. “I see this as, largely, an extension of what I've been doing over time,” he said of his new role. “I'm just continuing my practice in another place I see as being able to support it.”

“Deciding to join Mintz was an easy thing to do,” he said.
