Daniel Anthony Ivankovich (born November 23, 1963) is an American orthopedic surgeon, humanitarian and blues musician.

[9][10][11] His mother, Olga Ivankovich, is a primary care doctor and the clinical director of the Rush University Pain Center.

[14][15] Ivankovich completed additional fellowship training in adult joint reconstruction,[14] with research emphasis on osteonecrosis and hip replacement in medically co-morbid populations.

[4] From 1981 to 1987, between undergrad and medical school, Ivankovich worked as a radio announcer, production engineer, and graduate advisor at WNUR-FM in Evanston.

[6][13] Ivankovich later worked as an announcer and producer for WCKG, the top-rated rock music station in the Chicago market.

The full-time staffers call themselves the Bone Squad,[3][24][25] "a consortium of surgeons, primary-care doctors, and other medical professionals who treat the city's low-income population.

[29] He also spends time helping aging local blues musicians navigate the healthcare system, providing many of them and their families with free care and financial assistance.

[7] On April 9, 2016, he gave a TEDx talk at Northwestern University titled Transforming Chicago: OnePatient at a Time, as part of the TEDxNorthwesternU event Beyond Boundaries.

[30][31] Ivankovich also founded the Chicago Musculoskeletal Initiative, which has a goal of making healthcare for the poor population in the US a basic human right.

[4] After the 2010 Haiti earthquake, Ivankovich and his team airlifted thousands of tons of medical supplies to the country's capital, Port-au-Prince.

[26][33] While making rounds through the multiple tent-city medical camps, he and colleagues from Handicap International discovered nearly 50 patients with severe spinal cord injuries.

[15] After his appearance on the program, Ivankovich was contacted by "Massive" Mike Williams, a retired power forward who played in the NBA for the Sacramento Kings and Atlanta Hawks.

Williams had been shot eight times and paralyzed from a spinal cord injury suffered in 2009, when he tried to break up a fight while working as a security guard at an Atlanta nightclub.

[41][42] In July 2015, Ivankovich was featured on CNN Heroes, a series spotlighting "everyday people changing the world," for his nonprofit medical work.

He was honored on CNN Heroes: An All-Star Tribute, which took place at the Museum of Natural History in New York City, with his award presented by the rapper Common.

[46][47] He also supported organizing activities by a physicians' union, and criticized Cook County for spending too little on patient care and too much on administrative salaries and non-patient costs.

Ivankovich started going there twice a week, jamming with and learning from such blues luminaries as Junior Wells, Buddy Guy and Magic Slim.

[50] Ivankovich and his longtime musical collaborator "Killer" Ray Allison are founding members of the Chicago Blues All-Stars, and are the group's principal instrumentalists and vocalists.

[54] The band also features guitarist/vocalist Allison, singer Anji Brooks, Carl Copeland on bass, Daron Walker on drums, harmonica player Scott Dirks, keyboardist Roosevelt Purifoy, Jr., and a brass section with Johnny Cotton on trombone, Kenny Anderson on trumpet and Garrick Patton on saxophone.
