I worked with Mark for many years at USPS. I was a 204 b supervisor with Mark as my head clerk. He was very helpful, in many ways. He knew every postal regulation. I let him do his job and never bugged him. He was always there to help me out. The postal service will never be able to replace him. May you rest in peace my friend!!!

Mark was one of a kind. Very knowledgeable, filled with fun facts and his smirk just put a smile on my face. He will be missed deeply.
