J.C. grew up in the concession industry after his father, David C. Evans, started Gold Medal in 1931. He began working summers at Gold Medal in the 1940s, graduated from the College of Business Administration at the University of Cincinnati, and completed a two-year tour of duty with the Army's Counterintelligence Corp in Europe. He returned to the company as a salesman in 1950. J.C. was later promoted to sales manager, then to vice president and currently serves as Chairman.
J.C. was also the first recipient of the Outdoor Amusement Business Association's Pioneer Award, and received the Award for Entrepreneurial Excellence from the University of Cincinnati's College of Business. In 2000, he was honored with the NAC Bert Nathan Memorial Award, which recognizes leadership, significant contributions to the development and professionalism of the concessions industry and accomplishments and longevity in the theatre segment of concessions. With the Mickey Warner Award, he becomes one of only four people to receive both of the association's highest honors.
