Mammoth American Tattoo is a custom tattoo studio and art gallery in Denver's Whittier neighborhood. Established in 2014 by veteran tattooist William Thidemann, the shop features a tight-knit team including Matt Hays, Brett Herman, and Owlyn Madrone. The crew specializes across a wide spectrum of styles, from American Traditional to Japanese, alongside each artist's own distinct aesthetic, giving clients a broad range of custom work to choose from within one shop.
The studio maintains a friendly, professional atmosphere with a clean workspace and attentive service, creating a polished yet warm environment where creativity thrives. Clients are genuinely listened to and cared for throughout consultations and sessions, and the space doubles as a gallery, hosting rotating art shows alongside a solid music playlist for an inviting neighborhood vibe. Walk-ins are welcome Wednesday through Saturday from 11am to 7pm, with appointments also available for those who want to guarantee their spot for a custom piece.
