Brett Forrester

CEO & President
Born in South Africa to a father who headed the country’s largest aviation company, Brett Forrester has been surrounded by the aviation industry since childhood. Aviation is in the Forrester blood, as his brother owns an aviation financing and insurance company. Their father set benchmarks for sales and customer service that remain strong today, instilling the same principles in Brett.

Brett graduated from the University of Stellenbosch in South Africa with a degree in Commerce, majoring in Economics and Business Science.

Brett joined General Aviation Services’ market research department in 1994 under the watchful eye of NARA (National Aircraft Resale Association) co-founder Dan Dickinson. In his nineteen years at General Aviation Services, Brett completed, was involved in or consulted on over 300 transactions, including everything from light turbo props to intercontinental jets.

In 2013, Brett founded Jet Sense Aviation, LLC, realizing his vision of a full-spectrum aircraft industry firm. Our services include aircraft sales, acquisition, brokerage and consulting. 

Jet Sense is built on Brett’s belief that ensuring a smooth transaction and an outstanding experience for each and every client starts with accurate market information, and the process comes together perfectly, thanks to the passion and integrity he and his crew embody. Having seen every facet of an aircraft transaction from both sides of the table, Brett has a unique understanding of how to navigate through the complexities of these scenarios. 

With his combination of aviation genetics, a life immersed in aviation, broad international knowledge and 25+ years of experience and relationships to draw on, Brett is able to give his clients very detailed insight into the general, private and corporate aviation markets and brings a documented track record of successful transactions to the table at Jet Sense.
