Adam Kaiser and John Aerni, two Winston & Strawn litigation partners in New York, moved to Alston & Bird on Thursday, and most of their business from two large insurer clients, CNO Financial Group and AIG, is coming with them, they said.

Kaiser, 49, and Aerni, 60, were among a group of 70 lawyers who moved from Dewey & LeBoeuf to Winston & Strawn in 2012 as Dewey was collapsing. Overall, the Dewey group at Winston & Strawn has seen little attrition.

Kaiser and Aerni said that their move to Dewey was part of a large group decision, and that they have been looking for a better platform for their insurance clients.

Kaiser said Alston & Bird has a deeper insurance practice, with more attorneys in regulatory, litigation and transactional practices. He said while he believes Winston & Strawn is a great firm, it was not focused on building out an insurance practice and had little firmwide coordination in insurance litigation.

Meanwhile, CNO and AIG have retained Alston & Bird for years for various matters, Kaiser said. “They [Alston & Bird] have the depth and expertise in the insurance arena and the existing relationships,” he said.

“It was appealing because Alston has a good insurance practice across the board,” Aerni said.

Kaiser said he defends AIG in class actions, while Kaiser and Aerni represent CNO in class actions, reinsurance and general litigation.

The two came to Alston & Bird after meeting John Cambria, a senior litigation partner in New York, through a mutual in-house counsel connection. Cambria said Atlanta-based Alston & Bird has about 125 lawyers in New York, including about 35 to 40 litigators.

A Winston & Strawn spokeswoman did not return a message seeking comment.
