Arturo Diaz, born the third child of the late Mariano Diaz and Jovita De Guzman on December 15, 1928, in Manila, Philippines. He found love and was united in the holy matrimony to Emma Rey on the 14th of December 1957. This union was blessed with a daughter and four sons.

Arturo, at a young age, served in the United States Army during World War II and was deployed in Okinawa, Japan. After his military duties, he went to college and graduated with a degree in Bachelors of Science in Mechanical Engineering at Manuel L. Quezon University in Manila, Philippines. He worked as an educator in Guzman Institute of Technology.

Arturo is a quiet, strong, and humble individual. He lived a simple life with no interest in anything material. His family and their happiness were the most meaningful concern for him. He spent most of his life looking after his family, making sure that they are all fine. For him there are no riches and treasures greater than his own family.

Arturo quietly passed away on Sunday, February 20, 2022, at 11:14 in the evening in his home in Pittsburg, CA.
