He graduated from Poly Prep Country Day School in Brooklyn in 1963 and earned a B.A. from New York University. After attending New York University Law School, he left to take over his family's pharmacy business. He transformed the small business into Kinray Inc., a major pharmaceutical distributor.

Rise to Success

Under Rahr's leadership, Kinray Inc. became a leading pharmaceutical distributor, serving over 2,000 pharmacies in the Northeastern United States. Rahr's strategy included stockpiling pharmaceuticals and leveraging drug price inflation to maximize profits. This approach, while successful, later attracted controversy due to consumer ethics concerns. In 2010, he sold Kinray to Cardinal Health for $1.3 billion, which established his status as a billionaire.
