Long-time radio personality Bill Heywood will be back on mornings each Saturday 5 to 8am 620 KTAR. Teri Dozer, wife of the Diamondbacks president Rich Dozer, has filled the post for the past several years. There will be some who feel this further entrenches KTAR as serving the senior audience, and so be it. Heywood, a radio professional for decades, will draw from all ages.
