David Holtze: Food entrepreneur
David Holtze's career trajectory took an abrupt turn when he left a cushy job in interactive marketing to live on the road, slinging meat-free hamburgers and healthy grub in 2011. Now he’s the proud owner of a Green Truck, part of a fleet of biodiesel vehicles that have become staples on the Southern California food truck scene. As a business-oriented activist, he has a clear message: Be kind to your body and be kind to the planet. Taking a triple bottom-line approach, he believes profits come from being green, lean and crunchy.
