Meet Leonard Schleifer
“My luckiest break was convincing George D. Yancopoulos, Regeneron’s President and Chief Scientific Officer, to partner with me to found and build Regeneron. At the time, he was heading toward a prestigious career in academia but, somehow – with a little help from his father – he made the decision to instead pursue breakthrough science at our entrepreneurial biotech, through which we have helped millions of patients since.”
