Making sense of digital accessibility

Let us help you feel less daunted.

Transformative Accessibility Consulting

Tamman believes digital accessibility makes your business better. Technology alone cannot guarantee compliance of your digital properties. So, as a creative, technical, and accessibility services firm, we take a human-centered accessibility first approach when partnering with funded startups, businesses, nonprofits, and enterprise-level clients.

We’re passionate about building digital properties that are available to everyone. 

We know you have competing priorities and limited time! Tamman’s consultants work within or beside your team to integrate an ethos of accessibility and inclusive design throughout your organization. As your comprehensive digital accessibility partner, we help you shift mindsets and enhance skill sets by offering:


Testing & Remediation

Ensure your digital properties, assets, and documents meet the necessary standards.

Using a range of tools and expertise, we elevate barriers and defects. Findings are outlined and prioritized, so a roadmap to address them can be established.


Common Sense QA

Optimize your digital documents and assets for your employees, partners, and customers.

Technology alone cannot guarantee compliance! Our human-centered process combines the best automated tools with manual testing procedures.


Training & Workshops

Build your in-house accessibility champions.

From executive briefs to individual coaching, we cover everything from the fundamentals to deep dives into tools. Share your priorities, and we’ll implement our curriculum or custom-create one for your team.


360° of Inclusion

Let us help you tap into the largest underutilized workforce in America.

The Sierra-Tamman Collaborative provides comprehensive accessibility to human resource and employment services, from individual accommodations and training to physical and digital solutions.


Technical Consulting

Tamman can successfully build and launch your accessibility solutions.

Our in-house solutions consultants, accessibility-certified software engineers, and technologists are ready to help meet your needs with the highest quality, highly customized digital development projects.


Team extension

Do you need in-house accessibility experts on your team?
