Doc Holiday (Jeff Duncan) began his radio career at age 17, while attending high school in New Jersey. By 1990, Doc made his way to Orlando and WXXL-FM 106.7 for the "Doc and Johnny Magic Morning Show". After 17 years at XL106.7, Doc made the decision to leave WXXL and the morning show. Doc's credits include the announcer for the final season of "Family Double Dare",  arena announcer for the Orlando Predators, announcer for both the Atlanta Braves and  the Houston Astros spring training games and ESPN and Fox Sports Soccer TV work as well as freelance voiceover work. In September of 2007 Doc joined WWKA-FM 92.3 as the morning host. Doc has three children; Jeffrey, Gary, and Zachary.

8-2010 WWKA-FM 92.3 morning co-host Doc is no longer a part of the "K Morning Crew". Program director Len Shackelford told Scott Maxwell of the Orlando Sentinel "Doc’s no longer on the air. We appreciate everything he has done on for us, and we wish him the best." Doc did tell me he is still under contract with Cox, as Shackelford told Maxwell. The morning show is being handled by Grace Vasquez and producer Skid.
