Answer 1

"It is with deep sadness that we inform you that Art Berg, CSP, CPAE, and Speaker Hall of Fame unexpectedly passed away today. He became ill last evening and died in his sleep early this morning from what appears to be a possible reaction to medication. His passing leaves a void that will not be easily filled. His unconquerable spirit and his love for life will be with us and inspire us forever. INVICTUS!"
