Deaf Development Programme

About Us

The Deaf Development Programme (DDP) is a project of Maryknoll Cambodia, a US-based Catholic Mission organization serving the poor in 35 countries worldwide.  At DDP, we are dedicated to: 1) working alongside deaf people and their families to assist them to integrate into society; and, 2) achieving independence and equality for the 51,000 plus deaf people in Cambodia.

We work to remove the barriers preventing deaf people in Cambodia from achieving equality by providing Cambodian Sign Language research and development, education and job training courses, community development activities, Cambodian Sign Language interpreting services and social services.


Deaf people are accepted, respected and included as equals in all aspects of Cambodian society.


Our mission is to empower deaf people to develop their education, language, employment and community, and to raise awareness and understanding of deafness, deaf people and their culture within Cambodian society.
