It was in 1966 when a group of company physicians organized themselves to form the Industrial Medical Association of the Philippines (IMAP).
In 1976, Dr. Gregorio Dizon initiated the merging of the three occupational health associations:
- Industrial Medical Association of the Philippines (IMAP)
- Philippine Association of Occupational Health (PAOH)
- Phil. Association of Compensation Medicine (PACOM)
to become the Philippine Occupational and Industrial Medical Association (POIMA ).
The 350 physicians members of POIMA formed the first six (6) chapters, namely Baguio- Benguet, Cebu, Negros Occidental, Laguna, Southern Mindanao, and Northern Mindanao.
PCOM has been accredited by the Department of Labor and Employment (DOLE) as a training institution to conduct the Basic Course on Occupational Medicine (BCOM) for doctors and dentists. This training is mandated by the DOLE for those providing health services
in all workplaces. It has conducted this course all over the country both in Metro Manila and through its chapters.
