Welcome to the 50 Most Powerful Physician Executives recognition program. Modern Physician and sister publication Modern Healthcare co-sponsor this annual recognition program. Readers vote for one of 100 physician executives who make up the final ballot. The 50 physicians who receive the most votes make the final list, with the ranking determined by the number of votes received. Modern Physician and Modern Healthcare reserve the right to resolve voting irregularities. The nomination period for the 2008 competition closed on Dec. 7, with more than 7,300 nominations received. Voting will begin Dec. 23 and run through Jan. 25, 2008. The final ranking will be published in the April 7 issue of Modern Physician and the April 14 issue of Modern Healthcare.
