Getting to know your SD team

John Kummer & Keith Shelburn

We are thrilled to announce that two business aviation veterans have joined the SD executive team – Keith Shelburn as VP of Aviation and John Kummer as VP of Strategy and Programs. Their first-hand knowledge of the demands faced by today’s flight departments provides invaluable insight that will help us keep our products and services responsive and relevant. Their aviation and management skills will be used to help SD stay focused on the needs of its customers.

Keith will be responsible for managing SD’s flight department, which also serves as the test bed for all new SD products and services. John will oversee commercial strategy and new program development with the customer in mind.

John most recently worked for 3M as director of aviation, training and chief pilot flying Gulfstream IV, V, 550 and 650 aircraft. Keith comes to SD from DuPont where he began working in 1981 as a pilot, and served 11 years as aviation director. He has flown numerous corporate aircraft including all Gulfstream types, from the Gulfstream GI through to the Gulfstream G550, on which he is currently qualified.
