David Rimmer is a successful, innovative and highly respected business aviation executive and investor.
His aviation career began more than two decades ago after a successful 25-year career in media, which included programming and leadership positions at ABC, NBC, Bloomberg and Sony as well as several local radio stations.
David’s passion for aviation and his deep understanding of the needs of high net worth and high profile colleagues and customers has led to senior leadership roles at three large aircraft charter and management providers: ExcelAire, Alerion and Talon Air. Beginning as a charter sales executive, David quickly rose through the ranks, becoming president at ExcelAire and the companies that followed.
During his decade-long tenure at ExcelAire, the company’s fleet tripled in size while charter sales increased dramatically. He remained closely involved with the charter sales and customer service delivery process, specializing in complex domestic and international itineraries, working closely with performers, political and religious figures, business leaders and ultra-high net worth individuals. David’s subsequent companies achieved similar successes.
Among the aircraft David has managed at the three companies: Sikorsky S-76, King Air 200, Lear 55 and 60, Cessna Citation Bravo, CJ3 and Sovereign, Hawker 800/850/900, Gulfstream G200, Bombardier Challenger 601, 604, Global Express and 5000, and numerous Embraer Legacy 600s and Gulfstream GIV/GIV-SP, 450, GV and G550. He is known as a discreet and trusted adviser to aircraft owners, charter brokers and charter clients.
David is a battle tested leader with an intense focus on high standards and safety. In 2006, he was one of seven survivors of a major aircraft accident in Brazil that made worldwide news. He used his media and interpersonal skills to help overcome the accident and, in the process, became a leading aviation safety proponent, speaking to aviation groups and global media about his experience.
David remains committed to personal and professional growth. He became an NBAA Certified Aviation Manager (CAM) in 2020, is a Fellow at the prestigious Royal Aeronautical Society (FRAeS) and previously served as a board member of the Air Charter Safety Foundation, NBAA Corporate Aviation Management Committee and was Chairman of the NATA’s Air Charter Committee.
He also serves as a Senior Advisor at GoCrisis, a leading provider of crisis and emergency management services and on the Board of Advisors for Hopscotch Air.
