Upcoming Conferences


Members of the Chax team speak at or attend most premiere accessibility and Adobe innovation events. As the pace of technology continues to evolve exponentially, so does how the experts on our team integrate accessibility into our clients’ digital experiences. From updates to Title II of the ADA to assistive technology advancements and training program initiatives to artificial intelligence (AI) the future of accessibility unfolds rapidly. This year, our experts are presenting topics designed to shape your thinking about how to continue to integrate accessibility and technology.

Our Speakers


We have presented at conferences and hosted workshops all over the world. Whether it is a presentation, webinar, or training class, our subject matter experts customize their talks to meet the unique needs of your audience to ensure maximum impact either in person or online. We are available to speak in person or online, covering the prescribed topic and incorporating learnings that can be immediately used by your team.

Document Accessibility

The costs of externally remediating assets can compound exponentially over the years. To maximize return on accessibility investment (ROAI), we like to establish a framework to educate your team and partners to produce and maintain a more compliant digital ecosystem.

We specialize in accessible documents. Our expert designers are available to train, coach, and directly assist you through collaborative educational sessions.
