Andrew J. Miller, known as Andy J. Pizza, is a New York Times Bestselling illustrator and educator who guides artists through the psychological hurdles of a professional creative career. As the creator of the Creative Pep Talk podcast, Miller utilizes high-energy metaphors and clinical research to bridge the gap between artistic intuition and consistent discipline. His recent project, the Invisible Things series, has evolved from a viral illustration set into a best-selling book that helps audiences visualize abstract emotions and traits. A verified Skillshare Top Teacher, he has transitioned from high-level commercial illustration for brands like Google and Starbucks to a video-first education strategy. He frequently explores the intersection of neurodivergence and productivity, specifically positioning ADHD as an asset in the creative process. His long-term collaboration with author Brad Montague and appearances at Adobe MAX highlight his role as a bridge between technical design industries and the mental health needs of contemporary creators.
