Berkshire Hathaway HomeServices Florida Realty purchased the John Naumann & Associates real estate brokerage a week before Hurricane Ian battered Sanibel on Sept. 28. More than three months later, after suffering light damage from the storm, the Sanibel & Captiva Islands Chamber of Commerce celebrated the opening of the real estate office. John Naumann & Associates served the island for more than 40 years before being acquired by Berkshire Hathaway.
