Longtime KFGO personality Larry Ristvedt announced his retirement today, leaving the radio station after 34 years.
He cited health reasons, having been recently diagnosed with ALS, also known as Lou Gehrig's disease.
Ristvedt, half of the station's popular "Tom-N-Larry" show, is known for his quick wit and good humor.
The 68-year-old steps aside as farm broadcaster and morning show host at 790 AM. Filling his spot will be Shawna Olson, who was named the station's agri-business and farm director.
Ristvedt will say his goodbyes from 11 a.m. until noon today on the "Jack and Sandy" show.
