Harshad Reddy is a third-generation scion of the storied Prathap C. Reddy family that runs India’s largest hospital chain—Apollo Hospitals Enterprise—with over 10,000 beds. Armed with a BE in manufacturing engineering and management from the University of Warwick, Harshad was the driving force behind the establishment of the Apollo Proton Cancer Centre (APCC) in Chennai in 2019—the first such facility in South and West Asia. Apollo is currently working to operationalise a second Proton Cancer Centre in the Delhi National Capital Region (NCR), which is expected to become functional in the last quarter of FY26. Proton therapy ensures zero entry or exit load from radiation and avoids exposing non-cancerous tissues—making it one of the most precise cancer treatments available. Setting up the Chennai centre was a complex, multi-year effort. “It was like installing a cyclotron—a nuclear reactor—in the heart of Chennai,” says Harshad. Securing approvals from the Atomic Energy Regulatory Board alone took two years. Built at an investment of ₹1,250 crore, APCC has treated 1,750 patients from around the world, including 500 in FY25 alone. Earnings from APCC rose 23.8% to ₹327 crore in FY25, up from ₹264 crore in FY24. On the personal front, Harshad is a sports enthusiast and a passionate supporter of Manchester United. He stays fit through running and cycling, having already participated in several half-marathons. His long-term goal: to run the Boston Marathon. Fortune India is now on WhatsApp!
