Trevor Van Winkle, Photo & Digital Asset Manager
Trevor moved to Mammoth after graduating from Biola University with a degree in Film Production & Editing. Falling in love with the area while visiting family and exploring the backcountry, he chose to remain in town rather than return to Los Angeles – a decision he's yet to regret. First coming into contact with MLTPA staff through the Mammoth Lakes Film Festival, he has since worked as a field photographer, photo librarian, and digital assets manager. He also works as a freelance photographer/videographer, post-production media specialist, and as a stage manager and lighting technician for Mammoth Lakes Repertory Theatre. In his free time, he can often be found running the MLTS (particularly the Town Loop), and has self-published his first novel, a high-fantasy epic entitled "The Gräzland Tales", largely inspired by the grandeur and beauty of the Eastern Sierra.
