About Us

Deaf Defy is a Deaf-led team of language acquisition specialists, audiologists and interpreters who share a passion for improving the lives of Deaf children. Using a medical mission model, we travel to refugee camps and areas of conflict, bringing audiological care, hearing aids and, most importantly, sign language to Deaf children in need.
