In Memory of Preston G. “Gil” Gaddis II

Preston G. “Gil” Gaddis II
September 20, 1938 – May 23, 2024

It is with a heavy heart that I pass along news about the passing of our long-time friend and colleague, Preston G. “Gil” Gaddis II. Gil joined the firm of Crowe & Dunlevy in 1965, after graduating with a Bachelor of Arts degree from the University of Oklahoma and his Bachelor of Laws degree from OU in 1962. Before joining Crowe & Dunlevy, Gil also served in the Office of the Army Judge Advocate General in Washington D.C. from 1963 to 1965, and he attended Georgetown University where he received a Master of Laws degree in 1965.  

Gil built our Firm’s Aviation Practice Group from the ground up, becoming a nationally recognized expert on commercial aircraft financing. Leveraging Oklahoma City as the location where the Federal Aviation Administration’s record-keeping center is located at the Mike Monroney Aeronautical Center, Gil became the master of all aspects of aircraft transactions. A great story about Gil’s practice and how it came to be, can be found here – Financing Specialist Fills Friendly Skies Lawyer Arranges Aircraft Purchases ( 

Gil only stepped away from his practice earlier this year when his health began to fail. During his 60 years at Crowe & Dunlevy, Gil developed a vibrant Practice Group, but more importantly, he mentored and befriended generations of lawyers, bankers, financial professionals and created business relationships and friendships that span the entire world. I consider it a privilege that I was able to be mentored by Gil and I am so thankful for the years I was able to work beside him. His generosity, laugh and sense of humor (not to mention his homemade ice cream) are so greatly missed and my life was richer because I knew him and had him as a friend and confidant. I am sure that I speak for everyone who knew Gil Gaddis when I say that the aircraft industry was forever changed by his wisdom, his work ethic and, most importantly, his integrity. Those who follow in his footsteps at Crowe & Dunlevy only hope to leave half the impression that Gil left on so many.
