Rojas lived with Willard and Bertha Shupe while in Colonia Juárez, and they convinced him to attend English-language LDS Church meetings in order to assist him in learning English.
Rojas married Marcella Burgos, a recent Benemerito graduate, in 1969 in the Mesa Arizona Temple.
Rojas continued to work for the Church Educational System and later in the area administrative offices.
In 1988, Rojas and his wife set up a business translating technical manuals from English for American companies with factories in Mexico.
When Rojas moved to Mexico City in 1964 he was immediately called as stake superintendent of the Young Men's Mutual Improvement Association, a calling equivalent to stake young men president in the current system of the LDS Church.
