Amy B. Briggs joined Farella Braun + Martel LLP as partner in San Francisco.

Briggs advises clients on complex business litigation matters related to insurance coverage and bad faith disputes. She represents policyholders in the real estate, construction and healthcare sectors.
Briggs, an insurance recovery litigator, joined Farella Braun + Martel as partner in San Francisco from Manatt, Phelps & Phillips. She joined Manatt in 2008, when it merged with Steefel Levitt & Weiss PC.
Her move comes after Manatt decided to move away from policyholder representation in favor of insurance companies, she said.
"That presented a conflict with my clients and so, I moved to a firm that I knew would be dedicated to maintaining an insurance recovery practice on behalf of policyholders," she added.
What attracted her to Farella was its status as a regional firm with a national reputation.
"Notwithstanding that they are regional, they have a national reputation particularly in the area of insurance recovery. A number of their lawyers are routinely ranked at the top of their field and that really spoke volumes to me," she said.
Briggs represents clients in the real estate, construction and healthcare sectors. Her recent work includes the representation of San Francisco construction contractor Webcor Builders in connection with the Millennium Tower litigation.
"I have always thought that this was a really interesting area of practice because it generally involves two layers of the law. You have the coverage issues that are involved in your dispute with an insurance company over what the policy covers, but then you also have to understand the underlying claim that is giving rise to the insurance claim," she added. "I've always felt like it was a two for one deal and I've always found that intellectually challenging and fun to work on."
Her first day with Farella was July 1. Farella announced the move Wednesday.

Barbara Kosacz joined Kronos Bio Inc. as chief operating officer and general counsel in San Mateo.

Kosacz stepped down as chair of the global life sciences industry practice at Cooley and retired from the firm's partnership to serve as chief operating officer and general counsel at Kronos Bio Inc.
Her first day with the San Mateo-based clinical stage biopharmaceutical company was July 15.
"You reach a certain point in your life and a certain age where you do start to really think about how do I want to be spending my time. I've achieved a certain level of competency and for me, it's always been important to me to try to make an impact and I was trying to think about how do I want to continue to do that as my career, you know, at some point kind of slows down," said Kosacz.
Kosacz will continue in a consulting and advisory role at Cooley as senior counsel.
She was with Cooley for 28 years and joined its partnership in 1997. As chair of the global life sciences industry practice, she was responsible for an interdisciplinary team of over 30 lawyers. Kosacz' career in life sciences began when the patent law and corporate work her friends were doing for biotechnology companies sparked her interest.
"I found what they were working on as a young lawyer, extremely interesting and I really thought, how great it would be to be able to work with companies who were creating these incredibly novel therapies," she added. "And when I first started my career, I was working with more computer companies and that kind of thing, which was fun and interesting, but it didn't feel as compelling and so I got pulled into a couple projects for [biotechnology] companies. And I just thought, 'Wow I love this' and so I started learning as much as I could about the industry and talking to people and trying to sort of raise my hand to say 'Hey, if we have this kind of a project, I want to work on that' and then it ended up becoming a whole specialty."
At Kronos, she will handle legal matters in addition to overseeing the company's operations outside of research and development including human resources, IT, facilities, health and safety and public relations.
