Thai Union Group has announced Bryan Rosenberg has decided to step down as CEO of the Thai Union North America (TUNA) region, effective 1 January 2025. Rosenberg will remain with the company as Executive Director and Founder, supporting the frozen business with managing key customer relationships, coaching and mentoring its leadership team, and supporting Thai Union’s strategic interests in the North American market.

Rosenberg co-founded Chicken of the Sea Frozen Foods (COSFF) with Thai Union in 2006. In 2020, he assumed leadership of Chicken of the Sea International (COSI), when he became President and CEO of TUNA.
Daniel Halford, COSFF’s Senior Vice President of Operations, has been appointed as its new President. Halford will report to Rittirong Boonmechote, President, Thai Union Group, Frozen Business.
Earlier this year, Andy Mecs was appointed as COSI President.
“It has been our intent for some time to transition the leadership in North America,” Rosenberg said. “I remain fully committed to the long-term success of the business and have complete confidence in Andy, Daniel and their respective leadership teams to drive the next phase of each company’s growth.”
Under Rosenberg’s leadership, COSFF grew to be the top importer of shrimp and crab meat in the US.
“I want to thank Bryan for his leadership, partnership, and tenacious spirit in building COSFF to be one of the premier seafood importers in the US,” Thai Union Group CEO Thiraphong Chansiri said.
“He has worked tirelessly and been a key contributor to our success, most recently guiding COSI to the path of sustainable performance. I am grateful that he remains committed to our organisation, working with us on key strategic issues in the North American market.”
Rosenberg added: “I’m extremely proud of our accomplishments during my leadership tenure with Thai Union and would like to thank the executive team for the confidence they have always placed in me. Like many others, I’ve spent my entire career in the seafood industry and plan on remaining connected to it for many years to come as part of this next phase of my career.”
In addition to his role at Thai Union, Rosenberg has served on the National Fisheries Institute’s Executive Committee and Board of Directors, and the Seafood Task Force Board of Directors.
