Incorporated in 1991, International Medical Assistance Corporation (IMAC) a 501(c)(3) corporation was originally established to send medical equipment to third world nations including Ivory Coast, Nigeria, Ghana, Granada and Guatemala. After a few years the ministry began taking volunteer medical teams of doctors, nurses and lay people to countries in Central America.

The primary goal of IMAC is to spread the word of Jesus Christ around the world. Medical teams and medical equipment open the door for ministry. In this manner, individuals are ministered to both physically and spiritually.

Doctor Don and Sondra Barns are the founders of IMAC. Dr. Don practiced medicine for more than 40 years. Sondra taught school for more than 30 years.
