MCK

Mckesson Corporation

One of the world's largest healthcare companies, McKesson distributes branded, generic, specialty, and over-the-counter drugs to retail chains, community pharmacies, hospitals, and clinics across the U.S. and Canada, and supplies medical-surgical products to doctors' offices and other non-acute care settings. It began in 1833 in New York City as Olcott & McKesson, a drug import business founded by John McKesson and Charles Olcott, becoming McKesson & Robbins in 1853 when apprentice-turned-partner Daniel Robbins joined. Fun fact: the name "Robbins" comes from that early partner, and the company once made its own consumer medicines such as cough syrup and Epsom salts.
