Every day for the last two years, a Madison man has shown that through hard work anything is possible. “I know it sounds silly to you or crazy to you and you may not understand it,” 67-year-old Charles Satterfield said. “But, yeah, having a high school diploma and degree, ‘Charles G. Satterfield.’ Wow.” Satterfield received a GED diploma on Thursday at Madison College. The next morning, he went back to the school to work. He has been a custodian there for the last several years.
