What Others Are Saying
I wanted to thank you for the terrific job Mente did helping us acquire our new G450. This being our first aircraft we had no clue where to start or how to avoid the pitfalls in the marketplace. Mente took us by the hand and led us through the process with tremendous patience. For us, Mente’s most valuable asset is your ability to read and react to market conditions quickly to provide strategic guidance. We got much more airplane than we dreamed possible by listening to your counsel.
Thanks again for a great experience!
Director of Marketing and Public Relations
I meant it when I said what a pleasure it was to work with professionals for a change. It was refreshing to deal with calm, rational people who worked towards mutually beneficial solutions.
Vice President - Aviation Lender
I would highly recommend Mente group in both the sales and acquisition of an aircraft. They took the time to clearly understand my needs, provide competitive information, assist in the negotiation process, and complete both a sales and acquisition process. Their follow up and communication was exceptional throughout the process and second to none. There is only one place I would turn for help in my next acquisition.
It has been great working with Mente Group. As always, they expertly handled the relationship piece and kept us in the loop so we could keep our principal informed and calm. I assumed from the beginning that Mente would be a good fit, primarily because I personally know most of the team quite well. That confidence was validated every step of the way.
Retired Aviation Industry Executive
Reflecting on the entire process, Mente Group saved us much more than their fees, gave us confidence throughout the process and continues to support us today. With Mente Group, we have developed a strong, lasting relationship that is so much more than transactional. Mente group is our long-term aviation partner.
Grant W., Director of Aviation
It was not just the very professional way that Mente Group handled the disposition of our current aircraft and the acquisition of the new aircraft that sets them apart. They provided us with an extraordinarily detailed analysis that helped clarify our decision. They also provided completion insight that I don't believe anyone else in the industry has resident in their firm. Finally, they helped our treasury department mitigate a tax issue on our existing airplane with the assistance of their asset advisory team. I simply don't know of any other firm that has the breadth of knowledge that Mente Group has.
