Andrew was raised in Hillsborough, NJ, where he pursued filming short films and skits with his friends. He attended Bennington College, initially pursuing a degree in film and media studies, but quickly became an honorary member of the drama department. His senior work, a one man show titled "Where Are We Now", explored his diagnosis of autism and the concept of what it meant to "get better". This work caught the attention of Tectonic Theater Project, and he spent the next few years working with them on the Off-Broadway show "Uncommon Sense". He was featured in an Buzzfeed article that listed him as one of "the 5 Autistic Actors You Should Be Following Now", along with names such as Mickey Rowe, Alex Plank, Kayla Cromer and Coby Bird.
