Designing with accessibility in mind adds about 20% to the workload. But... 'Accessibility at the end' can add up to 80%.
Work smarter not harder.

The Short Story of Us

How Chad and Dax joined forces:

As accessibility professionals in our own rights, we shared many conference stages and over time became friends. We often chatted about accessibility solutions for each of our clients and one day we thought, "Ya know, I bet other people might like to hear what we have to say!" A few weeks later we started an accessibility podcast (Chax Chat). Fast forward two seasons and 65 episodes later and we realized we could take it a step further. So we joined forces and struck out on our own and Chax Training and Consulting was born.



What clients say?

Whether our clients are from conferences, private coaching, in-person or online training, the feedback we get continues to prove we solve accessibility problems and transfer knowledge that equates to more productivity and less accessibility compliance risk.

I just gave a training on PDF accessibility starting from InDesign, and my last advices were... if you properly followed the training steps and it still does not work, contact Dax or Chad!

I can wholeheartedly say I wouldn't be where I am in my accessibility journey if it wasn't for you two. The content shared via LinkedIn courses, FB group and the podcasts have made the world of difference, and the support along the way has been so appreciated... it's great to have you both supporting the cause and helping all of us in our journeys.
