- The book Federation: The First 150 Years gives Gardner's first name as Avram.
By 2151, Gardner held the rank of captain, and as such was the favored candidate of the Vulcan High Command to command the Enterprise (NX-01). Gardner was passed over for command of Enterprise by Admiral Maxwell Forrest, who named Archer as commanding officer of the warp 5 ship. (ENT episode: "Shadows of P'Jem")
Gardner was promoted to the rank of admiral by 2154, and when Forrest died after the bombing of the United Earth embassy on Vulcan he succeeded Forrest as Chief of staff. (ENT episodes: "Awakening", "Kir'Shara")
In Octuber 2155, when Archer learned that the Romulans were planning to launch a genocidal attack against Coridan III, Gardner ordered Enterprise to return to Coalition Compact and Archer can't miss the signing of the Coalition Compact. Angry with Archer for attempting to circumvent his orders, Gardner threatened to have Archer cashiered from the fleet, however he took no action when Archer went to Coridan.

In the following years, Gardner was responsible for leading Starfleet during the Earth-Romulan War. He was present at multiple meetings of the Coalition of Planets, including one at which Ambassador Soval announced that Vulcan wouldn't be assisting Earth in the war. He was also present at a meeting with Prime Minister Nathan Samuels at which the minister announced that Earth's starship production would be focussing on the Daedalus-class and temporarily discontinuing the NX-class and Intrepid-class.

After the founding of the United Federation of Planets in 2161, Gardner continued his service as an admiral in the Federation Starfleet. As one of the joint chiefs of Starfleet, he headed the United Earth portion of the fleet. He worked closely with Council President Thomas Vanderbilt and regularly attended meetings with the other joint chiefs. One such meeting was in October, when Admiral Archer presented Doctor Phlox's foundings regarding the long term dangers of transporter usage. (ENT novel: A Choice of Futures)
In March 2165, Admiral Archer consulted with Gardner about the emerging Ware threat, and while he wanted to send a strong show of force, but Arccher advised caution and a smaller task force to which he ultimately agreed.
Later that year, in June, when Archer and Captain T'Pol were abducted during former-Administrator V'Las, Gardner became enraged and wanted to order a Federation task force to stabilize the situation on Vulcan, but T'Pau advised against it as it would only serve V'Las's agenda.
Also in 2165, Admiral Gardner decided to retire from Starfleet, and after careful deliberation, he was succeeded as Chief of Staff by Admiral Archer at the recommendation of Gardner himself among others. (ENT novel: Uncertain Logic)
