Medtronic CEO Omar Ishrak takes to Twitter in answering the call to protect and spread company founder Earl Bakken’s message of corporate citizenship and public good around the world. When former Medtronic (NYSE:MDT) CEO William Hawkins passed the torch to Omar Ishrak last year, he charged him with a mission - to protect company founder Earl Bakken’s message of corporate citizenship and public good and share it with the world. Ishrak has certainly taken that to heart, spending his days jet-setting around the world (Bangladesh, Spain and Mumbai in the last month alone) - and he’s been Tweeting all the while.
