Greg Goldner

Age: 44

Occupation: CEO, Resolute Consulting

Goldner took a bit of a hit in 2013 when City Hall cut ties with his client Redflex Traffic Systems, the city’s red-light camera provider, after a bribery scandal. Nevertheless, the longtime Democratic operative and CEO of the public affairs powerhouse Resolute Consulting remains an influential mayoral consultant and played a key role in bringing ADM’s headquarters to Chicago.
