In 2244, Mendez was a Commander aboard the USS Eisenhower. He commanded it during the Battle of Donatu V alongside the USS Patton's CO, Lt. Commander Matthew Decker.(ST reference: Federation: The First 150 Years)
At one point in his career, he served as captain of the USS Maine. (TOS video game: Judgment Rites) Circa 2264, Fleet Captain Christopher Pike checked in with Commodore Mendez after an assassination attempt on the Tellarite Administrator Muso at Babel. He asked Pike to watch Muso as a favor and sent additional security assets to the planetoid (ST comic: "Alien Spotlight: Orions").
In 2267, Mendez was assigned to command Starbase 11, following the departure of Commodore Aaron Stone. One of his many duties aboard the base was to care for the crippled Fleet Captain Christopher Pike.
A few weeks after his arrival, the USS Enterprise arrived at the base, and Captain James T. Kirk told Mendez that the Enterprise was ordered there by him. It was later revealed that the message was falsified by Commander Spock, in order to kidnap Captain Pike and transport him to Talos IV. To aid in his mission, the Talosians created an illusory Commodore Mendez to escort them. (TOS episode: "The Menagerie")
