Leadership
Team

If my 25 years of experience in finance, marketing, and aviation have taught me anything, it is that great relationships are the keys to success. Creating connections with customers is what fuels my passion for Magellan Jets, where I’ve had the privilege of uniting people across the world through private aviation ever since we launched in 2008.

During my time as Founder and CEO, I have had the honor of learning from the best and brightest minds on the Magellan Jets’ team, as well as industry titans and global change makers we have had the pleasure of serving each and every day.

These crucial relationships with colleagues and clients are what inspire me. They are also the reasons why Magellan Jets is the powerhouse brand that it is today, consistently growing year after year earning recognition on the Inc. 5000 list of Fastest Growing Private Companies in America, Boston Business Journal’s Pacesetters (now Fast 50) list and SmartCEO’s Future 50.

Continually learning, innovating, and cultivating connections are the foundation on which I’ve built my career, beginning with my time in the world of finance on Wall Street at Paine Webber/UBS and Shearson Lehman Brothers. After leaving investment banking for advertising, I started to learn how to think outside the box, which helped me to lead a highly successful marketing team at America City Business Journals. Applying what I have learned to private aviation, I founded Jets International in 2001, where we successfully aided customers in achieving their goals, as well as optimizing their operations and revenue. Overall these experiences have taught me how to be a better leader, a better businessman, and a better person.

In addition to helping clients through Magellan Jets, I aspire to be a positive influence for my family, friends, and community. Currently I serve as Chairman on the Magellan Jets Board and Founding Chair of the Alumni Advisory Board for Raising a Reader Massachusetts. I’m also a member of the Young Presidents’ Organization (YPO) and George Washington University’s Advisory Board for Transformative Leadership in Disruptive Times, as well as the former Chairman of the Air Charter Safety Foundation (ACSF).

In 2002, Anthony made his mark at Jets International serving as the Executive Vice President, he helped the company to become one of the leading jet brokers in the country. Since 2008, Anthony has grown Magellan Jets in the same fashion. Experiencing 122% growth in 2015 and featured on Inc. 5000’s Fastest Growing Companies in America list two years in a row, Anthony’s dedication and leadership play an important role in Magellan Jets’ growth and success.

In addition to his success at Magellan Jets, Tivnan spreads his leadership beyond company walls into the Boston community. Anthony has served as a board member of the Entrepreneurs’ Organization and currently serves on the board of Camp Harbor View. His experience and mentor capabilities have granted him speaking engagements at countless organizations including Harvard University. He has been interviewed by Fox News and CBS and was named one of the 10 Boston Men of the Moment by Boston Common Magazine.

Before securing his role as Executive Vice President of Magellan Jets, Gregory Belezerian garnered experience in the world of finance as an analyst and financial advisor.

In his six years at Jets.com, he led the sales team as Senior Vice President in drastically increasing and sustaining their growth.

In 2008, Belezerian joined his Jets.com colleagues, Joshua Hebert and Anthony Tivnan, as founder and Vice President of Magellan Jets. As VP, he works in close collaboration with the executive team to manage the company’s development.
