About Judge Cosby

     Judge Don Cosby was appointed as Judge of the 67th District Court by Governor George W. Bush in 2000. Since then, he has been honored to preside over 450 jury trials and has worked to exemplify integrity and a commitment to truth and justice in and out of the courtroom. Prior to his appointment, he served as an attorney with banking institutions and the Federal Energy Regulatory Commission during the Reagan Administration. During his tenure of service, Don has developed a reputation for being honest, fair, and compassionate. These values, that are clearly demonstrated in his work ethic, are a direct result of his upbringing.


Don’s parents met in Japan, where his father served during the Korean War. After marrying and relocating to the United States, his father left the family

when Don was just three years old, leaving the three kids with a mother who did not speak English alone in a new country. Soon thereafter, Don and his siblings were placed with Lena Pope Children's Home, where his mother was eventually hired to work doing laundry, managing the kitchen, and later as a houseparent. Even during hard times, Don’s mother demonstrated a sense of resilience and commitment to her children that helped shape Don into the man he is today. At the age of 10, Don was taken in as a foster son by former Mayor Bob Bolen and his wife Fran. Don’s mother, Asako, is now 91 and is still employed at Lena Pope.


         As a child, Don demonstrated leadership skills and maturity that far exceeded his years. He received a full scholarship to attend Trinity Valley School in Fort Worth, where he would go on to become an honor student, recipient of the Headmaster’s Award, the first recipient of the Fellowship of Christian Athletes "Athlete of the Year" Award, and student body president. After high school, he continued in his commitment to learning and excellence by working full-time to put himself through both Tulane University and later St. Mary’s Law School.


         Judge Cosby and his wife Kathryn have been married for 29 years and have two adult children. They are members of Christ Chapel Bible Church.
