Christopher Sparkman was seriously injured when he was one of six employees shot in April by their co-worker, Geddy Kramer. Kramer then killed himself, but no one else was fatally injured.
 
Sparkman was shot in the stomach at close range with a shotgun. He is set to undergo his 14th operation on Tuesday.
 
On Monday, he and his wife, Jamie Lynn, celebrated their anniversary at WellStar Kennestone Hospital.
