To be considered a “voice of reason” in the midst of a problem, or a crisis, has allowed Mark Hooper to participate in resolving difficult reputational challenges. Building a strong complement of skills is only as good as having the tool that is foundational to strategic counsel: common sense. For more than 30 years, Mark has developed a diplomat’s ability to manage events and to get desired outcomes. This is his definition of tact and diplomacy: “The ability to assert your ideas or opinions, knowing what to say and how to say it without damaging relationships. Tact is the art of making a point without making an enemy.”

Mark has employed these skills while building a long and successful career at The Boeing Company. At Boeing, Mark led a team of 120 Marketing and Communication professionals responsible for media relations, crisis communications, executive communications, labor communications, employee engagement, and airline promotion and brand marketing. He has also advised other global corporations and has leveraged his radio and television experience to provide unique corporate opportunities to connect with audiences. Mark Holds a B.A. degree in Communications and an M.A. in International Politics from Washington State University.
