Tetra Society of North America

The purpose of Tetra is to recruit skilled volunteer engineers and technicians to create assistive devices for people with disabilities.

This unique program was developed in response to difficulties that people with disabilities experience in their search for greater independence and integration within their communities. The solutions are often simple but can change someone's life.

Tetra recognizes that people are not handicapped by their disabilities but by obstacles or barriers in their living environment. Volunteer engineers, design technicians, and health professionals work one to one with their clients to make assistive aids or modifications to their environment so that greater independence can be achieved.
