The mission of this non-governmental organization (NGO) is "to demonstrate the love of Christ to people affected by disaster, conflict and poverty." They provide humanitarian aid to people in need regardless of a person’s religious background, affiliation or experience.

Aid recipients are not asked to participate in faith-based activities in order to receive medical care or supplies. Volunteers are welcome regardless of faith as long as they can support the mission of Medical Teams International.

An Oregon businessman, Ron Post, founded Northwest Medical Teams (now Medical Teams International) in 1979, in response to reports of thousands of Cambodian refugees escaping the killing fields. Twenty-eight medical volunteers joined the first team to Thailand to care for survivors of the Khmer Rouge.

This work has now expanded beyond their International Headquarters and Distribution Center in Portland, Oregon. They now have offices in Seattle, Washington, D.C., Minnesota and Michigan. Additionally, Medical Teams International has field offices in Cambodia, Indonesia, Liberia, Mexico, Moldova, Sri Lanka, Uganda, Uzbekistan and Vietnam.

We use internationally accepted guidelines which are determined by the global health community. Our headquarters and field staff consistently review our commitments based on needs, capacity and potential for impact."

Their programs include:

Medical professionals from around the world volunteer on teams that address needs ranging from training midwives in Honduras to providing mobile medical clinics in internally displaced persons (IDP) camps in Uganda to forming emergency medical services (EMS) programs in Moldova.
