BUNNELL — Walk into Robert Snyder Jr.'s office, and there's a good chance you won't be the only one on your feet.Snyder is likely to be standing behind his desk. For the past two years, he's used a customized work station designed to promote healthier living. It's a practice Snyder picked up from his predecessor, Patrick Johnson, who served 11 years as Flagler County's public health director before retiring in June.
