This year now marks 140 years of Ganahl Lumber being in business. The company has since grown to 680 local employees and 11 total locations, including a 50,000-square-foot store that opened in San Juan Capistrano last year. Ganahl took over Ganahl Lumber Co. when he was only 27 years old when his father, John Sr., died unexpectedly of a heart attack in 1973.
