Anthony Castillo (left), manager of Norfolk's 911 center, gave Rotarians an insider's look at the inner workings of the city's emergency response center. It receives more than 500,000 calls a year and is staffed around the clock by workers trained to calmly and quickly get callers the right help in situations requiring police, fire or emergency medical personnel. Rotarians Michelle Nettles and Will King were among the group visiting the 911 center.
