Meet the team

Our smile maker’s are coming from all over the world and based in France and in Vietnam.

We are currently building a training curriculum. Every volunteer in our organization will need to take this training if they want to participate in our activities. This will provide information about safety in a hospital setting, basic information on ethics and appropriate social interaction with vulnerable populations. 

Each person involved in One Kid One Smile (OKOS) must read and sign an “Ethic Obligations” form and a “Declaration of Criminal Record” form. This is to ensure that every member of our team understands the sensitivity of our work and accepts to follow the rules we have put in place to ensure the children’s security. 

Most of the Vietnam’s based team members are in charge of at least one workshop. Our goal is that everyone involved in OKOS deeply understands the work we do by experiencing fieldwork with the children.

Jean-Yves Boulain

President of the French Organization

As graduate of the Lille School of Journalism, Jean-Yves pursued his career in media: radio, television and national daily press. Retired since 2004 in the Paris region, he wishes to devote his time and experience to people in need. As longtime friend of Grégoire, it was only natural that he took over the presidency of One Kid One Smile to ensure the link between France and Vietnam. According to him, the laughter of a child is a universal reward that does not need translation.
