Diamond Finance Corporation is a financial institution founded on August 2, 1976 by PMA Class 1942 classmates Colonels Felix Gonzalez and Mateo Dizon together with their supportive wives Aurora Gonzalez and Elma Dizon, along with Captain Demetrio Copuyoc and his wife Teresita Copuyoc. Other members of PMA Class 1942 became pioneer stakeholders of the company.  Altogether they built the foundation of Diamond Finance, a company committed to aid retired military men and their families with their financial needs. 

The primary clients of Diamond Finance were the retired personnel and beneficiaries of the Armed Forces of the Philippines. Through the years, its market has expanded. Today the company also services pensioners from the Bureau of Fire Protection, Philippine Veterans Affairs Office, Government Service Insurance System and Social Security System. The latest addition to the list is the Philippine Coast Guard, wherein we provide service to both its pensioners and active personnel. 

Today, the company continues to live up to the purpose of its existence and looks forward to new height, providing outright solutions to financial needs of its clients in an efficient and customer-centric approach.
