What we do

For over 30 years, Tetra Society of North America has been connecting people with disabilities to technically-skilled volunteers who imagine, create, design, and devise one-of-a-kind gizmos to address physical barriers in a person’s lived environment, either by hacking existing equipment to make it accessible or by inventing a completely unique solution.

In its fifth year, TetraNation showcases the work of Tetra’s of compassionate, skilled volunteers – and celebrates the differences their inventions make in people’s lives. We can’t thank our volunteers enough for their amazing work, so we’ve created a friendly competition to share these inspiring outcomes and help spread their message.

Take a look at some of our recent inventions, and please show your support with a Thumbs Up!
