Our History

Over the past three decades, Quintiles has pioneered new ways to tackle big healthcare challenges, starting with the way new drugs are developed

Born from the spark of statistical insight in a small university trailer, our company has grown significantly and strategically. Still, our goal remains the same: to make a meaningful difference in health and patient outcomes.
