weekdays 6am – 10am

It all began in a rice paddy outside of Tokyo, Japan. Actually, I was born on a military base there in 1956. My mother and father were born and raised in Polk County, Nebraska, which makes me a full (Big) red blooded Nebraskan!

I got my start in radio in 1974 in Salinas, California. That’s where my two sons were born…Dustin in 1983 and Cory in 1987.

I arrived in Central City, Nebraska, May of 1995 and started Mid-Days here at the ‘ole radio ranch. Now doing the “Morning Show” 6am-10am weekedays. Love to hear from you either by phone or email and thanks for listening!
