From his first experiences as an entrepreneur, William Hagstrom, CEO of Crescendo Bioscience, relates the importance of strategy and its integration into the business model. Added to this vision, he believes a CEO of a healthcare firm must have a thorough knowledge and understanding of the technical and scientific aspects pertaining to the business. Because there is little margin for error, the company leader must also be a multitasking dynamo with sound judgment who can deliver results. In short, the CEO must do more than talk, he must act.
