JACKSONVILLE, Fla. – He’s a full-time brain surgeon and part-time movie star. Dr. Alfredo Quinones-Hinojosa, a brain surgeon and researcher dean at the Mayo Clinic, came to the U.S. as a migrant farm worker and is now saving lives in the operation room. Both his research students and his colleagues at the Mayo Clinic call him Dr. Q, a name he didn’t expect others to call him.
