“Working with 11 Aviation was truly exceptional. Mark and his team found me an off-market Kodiak at a fantastic value and guided me through every step of the acquisition. The transition into management and training was seamless — I was flying confidently within days of closing. They continue to handle everything behind the scenes to protect the airplane’s long-term value. It’s rare to find a group this experienced, hands-on and committed.”
— Brett Ekblom, Kodiak 100 Owner
