Where Is William Thidemann's Tattoo Studio Located?

William Thidemann works out of Mammoth American, a tattoo studio at 1919 East 26th Avenue, Denver, CO 80205. If you want to visit or get tattooed, the site is clear on one point: all scheduling must be done by phone, not email, at 303-455-2855. So the practical answer is that the studio is in Denver, and a phone call is the required first step before any in-person visit.

Studio Details at a Glance

What This Means for a Visit

The location alone isn't enough to walk in. According to the site, appointments and consultations are arranged by phone, so the address is the destination after you've called, not a drop-in stop.

A reasonable sequence:

1. Call 303-455-2855 to schedule an appointment or consultation.
2. Confirm the time and any preparation details during that call, since the site routes all scheduling through the phone line.
3. Go to 1919 East 26th Avenue, Denver, CO 80205 for your confirmed appointment.

Common Pitfalls

• Trying to book by email. The site explicitly states scheduling must be done by phone, not email, so an email request may not get you on the calendar.
• Showing up without an appointment. Because booking runs through the phone, arriving unannounced isn't the intended path.
• Assuming the address is a separate gallery. Mammoth American is the studio tied to the contact and scheduling information, so treat it as the single destination.

Verifying Before You Go

Addresses and phone-based booking policies can change. Before traveling, call the number to confirm the studio is still operating at that location and that your appointment is set. The site also links to Twitter, Facebook, Instagram, and Flickr, which can be useful for checking recent activity, but the phone line remains the stated way to schedule.
