My point was that DPM's are BETTER trained than businessmen to run clinical medical departments. A med school president doesn't deal w/ med issues (clinically, at least) perse but rather the day to day operations/administration. Thus he can be a lawyer, MBA or any other degree as long as he has experience in admiistration, but not necessarily clinical experience. A department head in a hospital MUST have med knowledge. An HMO, obviously, hires usually on basis of business ability -- NOT medical talent.
So... Chief (of ANY medical setting) and CEO have nothing more in common, except they begin w/ the letter C. What are you trying to say? You won't find too many lawyers running a Dept. of Surgery at a hospital, I assure you. But you most certainly can (and WILL) find DPM's running surg. depts., etc.
