Occupation: CEO, Rehabilitation Institute of Chicago

This physician armed with an MBA is a fundraising force: In July, against the protests of some Streeterville residents (and with the help of M. Jude Reyes, No. 31), she plowed ahead with a $550 million expansion plan that, when completed in 2017, will triple the footprint of the nation’s top rehab hospital.
