Houston-based international aircraft brokerage Par Avion is marking a quarter of a century in business. The firm, started by president Janine Iannarelli in 1997, specializes in the buying and selling of preowned business jets.

“I have worked to build relationships and a company with a global presence that stands on the time-honored principles of honesty and integrity all while providing an exceptional transactional experience,” Iannarelli said. “Par Avion has prevailed through a number of economic cycles and other challenges, proving our longevity and relativity through the years in this demanding field.”

Rio Grande Pacific, a Texas-based railroad holding company, has worked with Par Avion for nearly two decades buying and selling corporate aircraft. “Par Avion and Janine Iannarelli have been trusted and invaluable advisors and representatives,” said Rio Grande chairman and CEO Richard Bertel. “Attention to detail, expert market analysis, and tenacious advocacy in multiple buy-side and sale-side transactions of increasingly sophisticated turbine jet aircraft have allowed our management team and executives to focus on our customers and building our businesses.”
