Early in 1980’s, the Medical Mission Group Hospital and Health Services Cooperative Philippines (MMGHHSCP) was simply a vision. It was a time when Nationalism was THE issue and the young doctors from the state-owned Davao Medical Center (DMC), Mindanao's only medical training center, were not exempt from participating in the struggle to help improve the condition in the country, especially pertaining to the less fortunate members of society. Healthcare was one area that needed healing. People came in droves to the DMC to seek medical attention as there was a dire lack of adequate healthcare, both preventive and curative, in their communities and most of them could not afford the services of a private hospital.

The first Medical Mission Group hospital opened in Davao City. It was housed in a small rented commercial space along J.P. Laurel Avenue, beside hardware stores and in front of the Davao Mental Hospital. It was a four-bed hospital with modest amenities but with an operating room, X-ray and consultation room and was manned by volunteer residents and consultants, mostly from DMC's Department of Surgery.

MMGHHSCP transferred the hospital to an old house at Barrio Obrero, which the Carriedo family rented to the organization. It became an accredited special surgical hospital with 12 beds. Many of the patients were surgical cases. Specialists from other departments in Davao Medical Center (DMC) also joined the growing mission.

The first Medical Mission Group outside Davao City was established through the Medical Mission Hospital in Tagum. It was a 25-bed secondary hospital created to serve the working class in the area. The hospital was also manned by graduates from Davao Medical Center.

The creation of the Medical Mission Group Hospital and Health Services Cooperative. In May 1990, the MMG Board of Directors approved a move to cooperative the two hospitals, and so was born the Medical Mission Group Hospital and Health Services Cooperative (MMGHHSC). After a series of consultations, seminars, planning, discussions and prayers, the cooperative hospital movement continued to grow.

The first Medical Mission Group Cooperative Hospital, a tertiary care 80-bed hospital, was inaugurated on November 16, 1991 in Davao City.

The MMG concept, principles and practices were featured in the Philippines Daily Inquirer, inspiring doctors and health workers in various parts of the country to establish their own health cooperatives. The first Medical Mission Group Cooperative General Assembly was held in Davao City on March 23, 1993. Members from all over the country attended, bringing new ideas, commitments, investments and new areas of membership.
