Smiles on Wings was founded in October of 2003 by Dr. Usa Bunnag, a native Thai dentist living and practicing in Maryland. In March 2004 the organization received 501(c)(3) tax-exempt status as a non-profit organization. In October 2003 a team of volunteers set out on the first in-country mission in Maesariang, a small town in Northern Thailand. Within a year and a half Smiles on Wings had gone back to this region two more times to provide care. When a devastating tsunami struck Southeast Asia on December 24, 2004, Smiles on Wings arrived in Southern Thailand within two weeks to provide immediate, direct, hands-on relief aid to the victims of the disaster.
