Erissa Duvall

Erissa Duvall

Everyone has their niche in the world where they find the most joy and fulfillment. For me that has become Accessibility. Some of my experience comes from my personal ordeals I have gone through as I have steadily learned more about what makes my brain tick and what makes my joints throw a temper tantrum. My professional experience has helped me along the way because it is where I learned just how diverse the options were for accommodations, treatment, and more.

I was initially thrown into the deep end during my amazing journey with the American Printing House for the Blind's Internal IT department. I gained insight to some of the struggles caused when environments, processes, technology, and attitudes are not accessible. However, I also experienced great joy every time I managed to help make someone's day easier by helping them be more independent and confident in themselves. Since then, I have held many other Accessibility related roles and made it my mission to spread Accessibility awareness. I've done so through by improving Code Louisville's Accessibility policies and coursework as a mentor, speaking at domestic & international events, providing support online, and so much more. I plan to continue to do what I can for as long as I am able.

I inspire people to embrace the potential of today!

This is what it means to me, broken down word by word.

Inspire - This is the method I trust and believe in. By inspire first (the why), I'm confident people will find instructions after (the how).
People - I don't work with organizations. I work with people! We should listen to hear, not to be able to respond.
To embrace - For you to be fully motivated, I want you to drive your practice from within. For your own reasons. That's why it's important that you embrace.
The potential - This could be so many things! Productive ways of work, applications, methods and much more. I want you to reach your highest potential and be the best you.
Of today - Whatever potential is available, I want you to be inspired to embrace it. In an evergreen world, everything constantly changes. This keeps me on my toes and keeps you informed on the latest and greatest.
