The AOPA Board of Trustees has selected Mark Baker as the fifth president and CEO in AOPA's nearly 75-year history. Throughout the past several months, the board searched for a pilot with true passion for general aviation and depth of involvement in the community. We were also looking for an experienced and seasoned business leader. Not only does Mark bring 35 years of involvement in the GA community as a pilot, he also has decades of experience in leadership positions in the home improvement industry, a business focused on the kind of service that has always been a hallmark of AOPA.
