Briner was born and raised in Maryland. He attended University of North Texas and studied theater prior to finding voice-acting work. In 2015, he starred as the voice of Mikaela Hyakuya, one of the two main teenage orphans who turns into a vampire in the anime series Seraph of the End, which was released through Funimation's broadcast dub Service. He voiced Elam, a boy who serves Arslan's main party member Narsus, in The Heroic Legend of Arslan. He voiced main protagonist Qwenthur Barbotage in the mech-themed anime show Heavy Object. A reviewer wrote on Anime UK News that she was impressed with the quality of the dub and that Briner and fellow voice actor Micah Solusod "have a lot to do with how instantly likably the characters come across, which helps carry the whole show".
