SHELLI PARKER As the year draws to a close, we say goodbye to 2020 and that chapter of our lives. Mark Hall, the Henderson County District Attorney, is closing the door to his 26-year legal career and his four years as District Attorney. Hall originally graduated from Texas A&M University with a business degree and started working at General Electric where he stayed for 10 years. Although he liked his job, he decided to attend law school at 32. âI enjoyed my job, but felt there was something more,â Hall said. âI thought of the legal field as a challenge and something I would like to do.â
