Sunghak "Andy" Baik joined Mayer Brown as partner in San Francisco.

Baik has joined Mayer Brown's tax transactions and consulting practice as partner from Ernst & Young LLP. He is based in the firm's San Francisco office.
His first day was March 17.

Baik's practice is focused on advising foreign companies, primarily from Asia who are investing in the U.S., regarding U.S. tax and cross border tax matters. Additionally, he also works with U.S. and European multi-national companies, who have operations in Asia and are looking for expertise regarding cross border tax issues.

Baik said he was attracted to Mayer Brown's attributes, such as its "robust global platform" and "deep bench," which fit with his practice.

"I was driven to Mayer Brown because of the opportunity to advise, for example my Asian clients, not just on tax, but you know, related services, legal services that Mayer Brown has a lot of capabilities in."

Baik said he does not expect his focus to change with the move, but he does anticipate he'll "target a broader range of clients."

"I'm very much looking forward to continuing to serve clients with their best interest in mind, but I think the additional attraction, as I said earlier, is I'll be able to bring Mayer Brown's strength and capabilities in many legal areas to my clients."

Prior to joining Mayer Brown, Baik spent 25 years at very large accounting and audit firms. He spent nearly a dozen of those years working in Singapore and Korea, where he advised on tax matters.

For Baik, what makes his practice unique is his focus on Asia-U.S. cross border matters.

"I think a lot of U.S. companies when they're investing in Asia have the additional challenge of navigating through differences in culture, norms and legal system. The environment may be very different from the U.S. so that makes it often challenging for a lot of U.S. companies. So the ability to provide tailored guidance based on experience and expertise in this area, many clients find it valuable."

Robb C. Adkins joined Baker & Hostetler LLP as partner in San Francisco.

Adkins joined Baker & Hostetler LLP as partner, and he's also leading the firm's new San Francisco office.

"I've been brought on board for what I think is, at least in my view, a very rare experience to be able to open a new office in a major legal market for a national law firm," Adkins said. "In my experience, those opportunities don't come around very often, certainly with a firm of the caliber of BakerHostetler. And so, I'm just really excited to take on this role."

Adkins joined BakerHostetler's white collar and investigations group as well as its complex commercial litigation group. His first official day with the firm was Mar. 9.

"I'll be leading, the San Francisco office, both in terms of my day job being a lawyer and doing white collar work and litigation but also exercising different muscles to help recruit and grow and continue to grow the West coast presence," said Adkins.

Adkins' spent a decade as a federal prosecutor in positions such as chief of the U.S. Attorney's Office in Orange County and as a member of the Financial Fraud Enforcement Task Force. He moved into private practice in 2011 and since then he has handled white collar matters, complex civil litigation and trial work.

He was managing partner of Winston & Strawn's San Francisco office, head of its west coast litigation group and co-chair of the white collar practice before joining BakerHostetler.

In his new role as lead of the San Francisco office, Adkins hopes to help grow the office strategically with a focus on the core strengths BakerHostetler already has, but may not specifically have in the Bay area.

Adkins describes his move to BakerHostetler as an easy one because he worked with several people from the firm in the past. The move will not change the focus of his practice, Adkins said.

"The joy and the satisfaction I get from doing white collar work are those instances where you're really able to help people, where you're able to take what appears to be a very scary situation, usually one that a company or an individual has never seen before. To be able to help them through that process, which is new to them, but not new to me. And then get them into a position where they can move on with their lives."

Paul Hastings LLP
welcomes Steven A. Marenberg as partner
from Irell and Manella LLP

Marenberg, a litigator known for his work with Hollywood heavyweights such as United Talent Agency, Warner Bros., HBO and The Walt Disney Co. has joined Paul Hastings as chair of its Century City litigation group and as chair of the firm's new media and entertainment litigation group.

"Essentially I am moving my practice over from Irell. The goal long term is to build an even bigger litigation practice by adding other top-notch entertainment litigators and having synergy with the first class entertainment transactional and finance group that is already at Paul Hastings."

Although he admired Irell & Manella, Marenberg said the firm was narrowing its focus and concentrating on areas that did not "have a lot of synergy" with his practice. As that was happening, Paul Hastings offered him a unique opportunity, Marenberg said.

"[Paul Hastings] had opened up a Century City office a couple years ago, starting with a first rate entertainment and media transaction group that had moved over from Loeb & Loeb," he said. "But the firm still lacked any capability on the litigation side. So there was a unique opportunity for me to move over to build the litigation practice and create synergy with the transactional practice."

Marenberg describes his practice as a "general complex litigation practice."

"But, I would say that most of the work I do and the industry that I am best known in is in the entertainment and media industry, which I suppose is not surprising if you are an LA-based litigator."

Profit participation cases, copyright cases and contract disputes are some of the other matters he's handling. Marenberg is also working on the dispute between the Writer's Guild and the major talent agencies. Marenberg is representing UTA in an anti-trust and labor case.

In his new role, Marenberg aims to "help build an entertainment and media group that encompasses both litigation and transaction, that can be a powerhouse in Los Angeles even more than it is" and "also grow the litigation practice, generally, in the Century City office," he said.

welcomes Allison Martin Rhodes as deputy general counsel
from Holland & Knight LLP

Martin Rhodes is an ethics and risk management lawyer based in San Francisco, who has built a practice representing lawyers, law firms and legal tech companies throughout the nation.

Her new role as deputy general counsel will shift her focus from multiple clients to a single one: Sheppard Mullin. Martin Rhodes will run the firm's legal department and handle risk management and conflict analysis with her co-deputy general counsel Charlie Barker and Michael Stewart.

Martin Rhodes worked with Sheppard Mullin before officially joining the firm. She said her work with Sheppard Mullin led to her natural transition into the firm after its long-time deputy general counsel retired.

"Prior to this we had been outside counsel on a variety of issues supporting Sheppard Mullin's legal department for a number of years," said Martin Rhodes.

She describes her practice prior to the move as "doing the typical thing lawyers do, generating business and serving clients."

What excites her about her move is the ability to take everything she has learned throughout her career and put that knowledge into action at Sheppard Mullin, Martin Rhodes said.

Martin Rhodes is a speaker and author. The Northwestern University Pritzker School of Law alumna co-wrote, "Hillman on Lawyer Mobility: The Law and Ethics of Partner Withdrawals and Law Firm Breakups," along with Robert Hillman, a professor at UC Davis School of Law.

Sheppard Mullin announced Martin Rhodes joined on Feb. 25. She brings about 15 years of experience to the firm.

"I have represented law firms and lawyers in legal ethics regulatory issues, litigation and law firm reorganization as an outside attorney for many years. And so now I have gone from outside to inside."
