Jeff was born March 10, 1962, in Chicago, Illinois, to John and Mary Segner. He spent his childhood in Illinois and Michigan, completing his undergraduate degree at the University of Michigan in 1984. He then relocated to New Orleans where he met and married Denise Henderson on June 17, 1989. She was the love of his life the entire 33 years they were together. Their beloved daughter Ashley was born December 4, 1991. He worked for several years tending bar at The Port of Call and as a registered EMT. Jeff graduated from Tulane University with a Master of Public Health in 1994 and worked as a clinical research site director at Benchmark Research for 18 years. He maintained his love of learning, especially in the sciences, throughout his life. 

Jeff was an avid scuba diver and he and Denise traveled the globe to dive in some of the world’s best sites. He was also passionate about photography, including underwater photography, and never went anywhere without his camera. Whether catching shots of jellyfish in Palau or just family gatherings around the pool, Jeff could be counted on to get the best pictures at every event. 

Jeff absolutely loved to fly and was fascinated with old planes. He was a licensed pilot, a charter member since 2017 of the Big Easy Wing and a Colonel in the Commemorative Air Force. He functioned as the Big Easy Wing Photographer and the Marshaller for wing. He was also a member of the Hammond Bayou State Escadrille and the Experimental Aircraft Association. 

He was an avid car enthusiast, and his prized possession was his 1989 Mark 3 Toyota Supra Turbo. Along with his close friends Dave and Thomas, he founded Crescent City Supras which eventually grew to include Supra fanatics throughout Louisiana, Mississippi, Alabama and Texas. He loved sharing his passion for fast cars with anyone who had an interest.  

Jeff was a loving husband and father and an amazing big brother. He had a larger-than-life personality that left a positive, memorable impact on those around him. Jeff’s intelligence, kindess and sense of humor will be remembered by everyone who knew him. 

He was preceded in death by his father, John Segner; and his brother, Scott Segner. Jeff is survived by his wife of 33 years, Denise Segner; his daughter, Ashley Segner; mother, Mary Emerson; sister, Laura Sullivan; brother, Chris Emerson; and other relatives.

His family is planning a private Celebration of Life.
