Mathes grew up a feral child in the deserts of the American Southwest who loved to read library books and take photographs. In 2019-2020 he was awarded a PEN America Writing for Justice Fellowship. He has worked as a screenwriter with Rehabilitation Through the Arts, is a two-time recipient of the Norman Levan Grant, a Jack Kent Cooke Scholar alumnus, an award-winning author of four books, photographer, book critic, screenwriter, and librettist. Although Mathes still struggles with subject-verb agreement and where to put commas, he is working with The New Press on a book/memoir, ILL SERVED, about veterans, mental illness, and mass incarceration. He loves his two daughters very much.
