I need to interview a physician and get their assessment of management in the healthcare field. do you believe your ceo should be a fellow physician?

No and yes: A ceo does not have to be a physician. Most are not physician. Chief executive officer has the function of overseeing the operation of a company, evaluating the finances, operations etc. Should be a person with business education and experience. Few doctors have that preparation in addition to their medical training.

No: Typically, the ceo has responsibilities as a communicator, decision maker, leader, manager and executor. The communicator role can involve the press and the rest of the outside world, as well as the organization's management and employees; the decision-making role involves high-level decisions about policy and strategy. As a leader, the ceo advises the board of directors, motivates employees.
