Chicago Slim aka Daniel Anthony Ivankovich (born November 23, 1963) is an American orthopedic surgeon, humanitarian and blues musician.
He is best known for his advocacy of the underserved in Chicago’s inner city as leader of the Bone Squad, a group of medical professionals who treat the city’s uninsured and underinsured.
From 1981 to 1987, between undergrad and medical school, Daniel Ivankovich worked as a radio announcer, production engineer, and graduate advisor at WNUR-FM in Evanston. He produced several shows at the CMJ-awarded station, most notably as host (under the moniker The Right Reverend, Doctor D) of Out of the Blue, which featured Chicago blues music, live performances and interviews.
The all-night show was picked up by KOST Broadcasting for syndication and ran in over 60 markets across the country from 1985 to 1987. Ivankovich later worked as an announcer and producer for WCKG, the top-rated rock music station in the Chicago market. While there, he met Stephanie Miller, who was then the station’s morning host. When Miller went to New York to work mornings at WQHT, Ivankovich partnered with her and produced the Hot 97 Morning Show with Miller and Howard Hoffman.
Ivankovich has subsequently appeared as a guest on Miller’s talk and music shows. In 2013, he and his wife Karla Ivankovich started hosting the radio show Life & Love With Karla & Dan on WVON.
