How a Doctor Became a Healthcare Tycoon

But by the mid-1970s, he saw opportunity in hospital equipment — specifically specialized beds for patient care. In 1976 he purchased a struggling firm, rebranded it as Kinetic Concepts, and transformed it into a major medical-technology corporation focusing on wound care and hospital equipment.
