Greene said he was both "humbled and surprised" to receive the award, which is presented annually to a select number of pilots in the national air medical transportation community.
The 2011 award recognized five individuals who have displayed excellence in aeronautical achievement and contributed to the safety of air medical operations.
Greene serves not only as one of the pilots at the base, but is the safety officer for his fellow crewmembers.
Flight paramedic Stacy Fiscus nominated Greene for the award.
"I'm very grateful for the nomination and the award," Greene said. "I was really quite shocked. It's such an honor to have been selected and I'm at a loss for words."
Brazil Air Evac Lifeteam Program Director Nicole Shaughnessy said Greene was a deserving recipient and is highly respected among his peers.
"Corey is phenomenal, not only as a the safety officer, but he's just a wonderful pilot," Shaughnessy said. "I can honestly say he's one of the best pilots I've every flown with."
She noted Greene's work ethic, aviator skills and the "safety culture," he has helped instill at the base.
"This award speaks to how highly his colleagues think of him," she said.
Greene said his desire to fly was born out of a chance meeting as a young child with an air medical helicopter in Des Moines, Iowa. After receiving a tour of the aircraft, the crew departed for a flight and the then 7-year-old Greene "was hooked."
"Since then, I've loved helicopters," he said.
Greene was raised in Humboldt, Iowa.
In 2004, Greene began his pilot training in Florida, where he spent two years as a flight instructor before moving to Arizona to fly tourists over the Grand Canyon.
In 2007, after consulting with a friend, Greene joined the national air ambulance company Air Evac Lifeteam, which has 104 bases throughout 15 states in the central United States.
In addition to the Brazil base, Air Evac Lifeteam has bases in Rushville, Evansville and Paoli and is the largest independently owned and operated membership based air ambulance service in the country.
"It has been great working for Air Evac," Greene said. "The crews I've had the privilege of working with are the very best. It's very easy to come to work every day knowing we're fulfilling our mission of helping someone in their time of need."
