Díaz was among the first seven recipients of the Profiles of Success Hispanic Leadership Award's in the Hall of Fame category.

His parents fled from Mexico in 1908 because they feared that Mexican dictator Porfirio Díaz would condemn them for their support of an armed insurrection against him.

[1][2][3] In 1910, the family moved to Phoenix, where his father José was hired as an Arizona Eastern Railway's roundhouse operator.

During this period of time, Diaz's siblings Salamon, Moises, Samuel, and Virgil Joseph were born.

[4] After experiencing discrimination there, Soledad and other Mexican women began selling enchiladas, tamales and other food to raise money to build a new Catholic church.

[1][2][3] Díaz met Feliz Amada and married her in 1929 in the newly constructed Immaculate Heart of Mary Catholic Church.

He decided to help feed the hungry children by setting up a food stand across the street from the school with the help of three companies who agreed to sell him hot dogs, buns, and mustard at discounted prices.

The council's objective was to bring both parents and teachers together in order to find a way to encourage kids to stay in school.

During this time, Díaz also became interested in the goodwill activities of the Friendly House and in 1948, headed the Board of Trustees.

[1][2][3] During the administration of President Bill Clinton, Díaz was appointed to serve in the National Council on Aging, a nonprofit advocacy and service organization that focuses its efforts on improving the health and economic security of millions of struggling older adults.

Members of the council participate in the White House Conference on Aging (WHCOA) which is held every 10 years.

[1][2] On September 1, 1994, he received a "Special Recognition of Excellence" which was presented by National Hispanic Heritage Month's Profiles of Success.
