Andrew J. West was born in Merrillville, Indiana and grew up in the nearby town of Lake Station. He was interested in acting from an early age, but he didn't actually get to throw himself into it until he went to Indiana University. At first he studied philosophy and anthropology, steering clear of the theatre department. However, that changed when he decided to start auditioning for university plays and began landing roles, including the lead in Eric Bogosian's "Suburbia". This marked a turning point in Andrew's life, giving him the confidence he needed to decide to pursue a career in acting. He began writing, producing, and acting in short films with his college friends, some of which went to the festivals and won awards.

After moving to LA with some of those same close friends, Andrew's talent and drive landed him a manager almost immediately and soon after he started landing roles. After he landed the role of the young "Christian Troy" in the cult classic FX show "Nip/Tuck", Andrew began to garner attention from producers and casting directors alike. He had simultaneous recurring roles on "Greek" and "Privileged", and landed guest starring roles on hit shows such as "Bones", CSI:NY, "Ghost Whisperer", "Castle", and "Body of Proof". Trying his hand at comedy, he landed the lead in the critically acclaimed web series "Rockville, CA" from Josh Schwartz. He also guest starred on "Shit My Dad Says" and "Suburgatory". These comedy shows led to him to scoring the lead roles in two network pilots: ABC's "Who Gets The Parents", opposite Jane Kaczmarek and Adam Arkin; and "Family Practice" opposite Christopher Lloyd and Jean Smart.

Recently Andrew shot the lead role opposite Jim O'Heir in the indie feature film "The Middle Man"; as well as the lead role in the Tom Kapinos / Warner Brothers pilot "Dead People" and a two-episode guest starring role on NBC's "Under the Dome". Earlier this year Andrew appeared in a multi-episode arc on the highly acclaimed, hit AMC series "The Walking Dead", playing the character "Gareth", the head of Terminus. He was voted #1 Villain of 2015 by Us Weekly. He also shot the lead role in the indie film "Walter" opposite William H. Macy.
