What is William Thidemann?
William Thidemann is a tattoo artist and visual artist based at Mammoth American in Denver, Colorado. His site William Thidemann functions as a portfolio and contact page: it presents a tattoo gallery, a featured-work section, and brief About and Contact information. The page also links to his presence on Twitter, Facebook, Instagram, and Flickr, so the site acts more as a hub pointing to his work than as a booking platform.
What the site is set up to do
The practical detail on the page is how appointments work: scheduling is handled by phone only, not by email, through Mammoth American at 303-455-2855. If you are trying to book, calling is the intended route; email is explicitly not.
Who it is for
- Prospective clients who want to see tattoo work before booking a consultation.
- People researching an artist's style rather than a shop's general services.
- Followers of his broader art, who may prefer the social links over the site itself.
How to use it
Start with the gallery to judge whether the style fits what you want, then call Mammoth American to ask about availability, consultation, and any deposit or preparation requirements. Because the site does not appear to list rates or a booking form, treat the phone call as the point where those questions get answered. If you are not local to Denver, ask directly whether the artist takes out-of-town clients and how scheduling works for that.
How do I book a tattoo appointment with William Thidemann?
Booking with William Thidemann is by phone only. According to the site, all scheduling must be done by phone, not email. Call Mammoth American at 303-455-2855 to set up an appointment or consultation. The studio is at 1919 East 26th Avenue, Denver, CO 80205.
What to do before you call
- Have a clear idea of the tattoo: subject, approximate size, placement, color or black-and-grey, and any reference images you can describe or send later.
- Know your availability and any hard deadlines (travel, events, healing time).
- Ask what deposit is required and whether it is applied to the final session or non-refundable, plus the shop's rescheduling policy.
- Confirm the artist's current books: some artists open limited windows, so ask when the next booking period starts.
- Ask whether a consultation is needed first, especially for large-scale or custom work.
If you prefer email or social media
The site lists Twitter, Facebook, Instagram, and Flickr, but these are not the scheduling channel. Use them to view healed work and current projects, then call the shop to book. If you reach voicemail, leave your name, number, and a short description of the idea; expect a call back rather than an email reply.
Practical next step
Call 303-455-2855 during shop hours with your idea and availability in hand. If you are not local to Denver, say so up front and ask whether the artist accepts traveling clients or requires an in-person consultation before scheduling.

What tattoo styles does William Thidemann specialize in?
The page for William Thidemann does not state a specific tattoo style or specialization. It presents the artist as a tattoo and art practitioner with a featured work gallery, and directs all booking to a phone call at Mammoth American in Denver — no email scheduling. So if you are trying to match a style to an artist, this site alone will not tell you.
How to judge the fit anyway
- Look at the gallery first, not labels. Style names vary between artists and clients. The featured work on the site is the most reliable signal of what this artist actually produces.
- Check the shop context. Work is scheduled through Mammoth American in Denver, so the shop's roster and environment shape the kind of projects available.
- Call rather than email. The page is explicit that scheduling happens by phone only. Have your reference images, placement, approximate size and budget range ready before you dial.
A practical next step
If you already have a style in mind — say, traditional, blackwork or fine-line — describe it on the call and ask directly whether it fits the artist's strengths. That answer, plus the gallery, will tell you more than any style list on a website.
For cross-checking an artist's style and reputation, official artist or shop profiles are more useful than directory listings:
Can I see examples of William Thidemann's tattoo work?
Yes. The site functions as a portfolio: it has a gallery of featured work, plus a link to a larger Tattoo gallery. That is the fastest way to judge his style before booking.
H3 What you can actually browse
- Featured Work — a curated selection on the main page, useful for a quick first impression.
- Tattoo gallery — the broader body of work, better for comparing consistency across subjects and sizes.
- About / Contact — background and studio details.
- Social accounts — Twitter, Facebook, Instagram and Flickr, where tattooers often post the most recent pieces.
H3 How to use the gallery well Look for healed photos, not just fresh ones; healed work shows how linework and shading settle. Compare several pieces of the same type (for example, black-and-grey versus color) rather than one standout image. If a design you want is close to something in the gallery, that is a reasonable basis for a consultation.
H3 Booking Scheduling is handled by phone only, not email, through Mammoth American in Denver at 303-455-2855. Have your idea, approximate size, placement and availability ready when you call.
For outside reference points on the same craft, you can compare portfolios at Instagram or browse artist profiles on Flickr.
Does William Thidemann accept walk-ins or is a consultation required?
A consultation is required. William Thidemann's page states that appointments and consultations are scheduled by phone through Mammoth American in Denver, and that all scheduling must be done by phone rather than email. There is no mention of walk-in availability, so the safest assumption is that you need to call ahead rather than stop by and hope to be tattooed.
Call Mammoth American at 303-455-2855 to ask about consultation timing, availability, and whether any walk-in slots exist. The page indicates phone is the only scheduling route, so emailing will not get you on the calendar. The site also links to Twitter, Facebook, Instagram, and Flickr, which can help you review his style before calling, but they are not scheduling channels.
If you are set on a specific artist and design, treat the phone consultation as the required first step. If you are flexible and nearby, you could still call the shop the same day to ask whether a cancellation or walk-in opening exists, but do not treat that as a standing walk-in policy.
