Dave is a considerate personal trainer who enjoys glamping.

Dave Griswold is a 40-year-old personal trainer who prior to the outbreak enjoyed glamping, travelling, and helping old ladies across the road. He is considerate and kind, but can also be very untrusting and a bit standoffish. When he was younger, he studied sports science at the University of Chicago but never finished the program. Physically, Dave is in pretty good shape but his knee was never the same after an accident he had while cycling. He is tall with bronze skin, brown hair and brown eyes. He grew up in a middle class neighborhood. He was raised by his mother (who he called everyday just to say hi), his father having left when he was young. He is currently single. His most recent romance was with a legal secretary called Hollie Byrne, who was the same age as him. They broke up because Hollie was fed up of friends getting on better with Dave. Dave's best friend was a personal trainer called Jaydan Russell. They enjoyed tennis together. They were inseparable. Prior to the outbreak he quit his job as personal trainer to travel the world. Feeling unease about his life, not really certain what was missing, he bought a one way ticket to Nyheim. Now, after six months on the road he is stranded in a foreign land, alone, trying to stay alive.
