Gary Doernhoefer


Gary graduated from Grinnell College and holds a J.D. from the University of Chicago Law School. Gary started out as a litigation associate for Mayer, Brown and soon moved in-house at American Airlines. At AA, he focused on major case litigation, antitrust, and, eventually, government affairs. In 2000, he became the initial General Counsel for Orbitz. After the Orbitz IPO and subsequent sale in 2004, Gary co-founded and served as General Counsel for Accertify, a credit card fraud prevention solution for internet merchants. Accertify was acquired by American Express in 2010, after which Gary served three years as General Counsel for IATA, the global trade association for the airline industry. Gary then joined the travel industry startup Journera as Vice President and General Counsel, until shifting his focus to developing ADR Notable. The catalyst for ADR Notable was collaborative work with faculty at the Moritz College of Law at the Ohio State University, studying the potential benefits of greater use of ADR by the airline industry.
