After proudly graduating from Pilot Point High School, Dwight served his country as a Sergeant in the United States Marine Corps from April 1966 to April 1968, including a tour in Khe Sahn, Vietnam. His dedication to serving his country was a testament to his character, and he carried those values of honor and integrity throughout his life.

On November 18, 2000, Dwight married his beloved wife, Mary Lydia Robertson, in Nocona. Together, they created a warm and welcoming home on their ranch, where they shared their lives with a variety of animals and a deep love for one another.

Dwight was an avid fisherman and hunter, often embarking on adventures to Colorado with his friends, where he created lasting memories in the great outdoors. After a fulfilling career as an insurance agent with Texas Farm Bureau, where he dedicated 34 years of service, he enjoyed retirement surrounded by family and the beauty of nature.

A member of the Montague County Cowboy Church, Dwight found a second family among his friends there, sharing his faith and love for the Lord. His unwavering devotion to his family, friends and faith defined his life.
