Please accept this Letter of commendation on behalf of Califon postal worker Greg. While I was out jogging I was confronted by a dog that I feared was about to attack me. Greg was on his normal route and immediately assisted me and prevented me from being attacked by this dog. He did not have to stop and help me and yet he did. As a retired government employee (county prosecutor) I feel it is important to recognize exceptional work and effort by fellow government workers. Please put this in Greg’s file.
