SAN DIEGO — U.S. Coast Guard Sector San Diego welcomed a new commanding officer during a change-of-command ceremony held on base Wednesday morning.
Capt. Jonathan S. Spaner assumed command responsibilities from Capt. Sean M. Mahoney as commander of Sector San Diego and San Diego Captain of the Port. The ceremony was presided over by Rear Adm. Joseph Servidio, Commander of the 11th Coast Guard District.
After more than 27 years of active duty service in the Coast Guard, Mahoney officially retired after the change of command.
Spaner reports to Sector San Diego from Washington, D.C., where he served as Director of the U.S. Coast Guard’s Office of Emerging Policy. In this role he was responsible for development of strategy on major issues including the Arctic, Western Hemisphere affairs, cyber security, and climate change.
The change of command ceremony is a time-honored tradition that ensures the continuity of command of the unit and its personnel. It is a formal ceremony and marks the transfer of total responsibility, authority and accountability for the unit and its assigned missions.
