A message from our founders

“As Group CEO of Sentry Aerospares,  I am truly passionate on the company fulfilling our value proposition of supporting aircraft operators across the globe with an industry-leading 24/7 AOG service for latest generation aircraft parts.

The merger of Aerospares 2000 and Sentry Aerospace to form Sentry Aerospares was a perfectly aligned strategic move for both companies which has accelerated our combined growth through the pooling of expertise, resources and multiple synergies.  

I derive a tremendous amount of pride from how our relatively small yet highly motivated team has made such a profound positive global impact in the Used Serviceable Material market and continues to innovate and push new boundaries.”

Adam Nemenyi, Group CEO

“When Acorn Growth Companies and Adam Nemenyi first presented the idea of a merger between Sentry Aerospace and Aerospares 2000, my two sons and I immediately saw the potential and benefits it would create for both companies. We have far surpassed all our expectations after one full year of operation. We are now a dominant player in the aviation aftermarket worldwide. It is a very exciting time for all of us.

I started in the aviation business in 1964 and this merger has rejuvenated me, even after all those years. As Executive Chairman, I have the pleasure of watching Adam Nemenyi, Tony jr. and Chris DiSimone take Sentry Aerospares to new heights and propel us into the future.”

Tony DiSimone Sr, Executive Chairman
