David McDonald started training for his job as president and chief operating officer of the OSI Group more than 25 years ago when he was hired as the company's first intern. McDonald ('87 animal science) grew up on a family farm in Northeast Iowa and initially planned on veterinary school after graduation from Iowa State. But with the help of career service director Roger Bruene, he landed the internship that would lead McDonald to becoming president of a $5 billion multi-national food processing company.
