Doña Angelita, as her students called her, was born in León in 1895 into a well-to-do family (her father was a pharmacist and her mother a housewife). She studied higher education at the Escuela de Maestras de León, where she gave her first lessons in shorthand, typing and commercial accounting.
In 1917, she was appointed teacher and headmistress of the school of La Pola de Gordón (León) by unanimous agreement of its Municipal Board. In 1918, after winning a teaching post in the National Teacher Training Examinations, she settled in the A Coruña village of Santa Uxia de Mandía, near Ferrol (Galicia).
At the age of 40 she was widowed and in 1928 she moved to Ferrol. In 1934, she was appointed manager of the National School for Girls at the Hospice of Ferrol, an institution in charge of socially integrating abandoned children through primary education, musical education and training in useful trades for the city (shipyards and public works).
Between 1938 and 1970, she published 16 textbooks on various subjects such as spelling, shorthand, typing, grammar, history and geography.
In 1945, she was assigned to the Instituto Ibáñez Martín in the city of Ferrol, where she became its director (1949-1959), a position she held until her retirement.
At the same time, she gave free evening classes at the San José Obrero School (made up of students from the shipyards).
She founded the ELMACA Academy (named after his three daughters, Elena, María Elvira and Carmen). At the academy, located in her own home, she gave classes to candidates for customs, postal and telegraph examinations and for entry to higher commercial studies. She had the highest pass rate in Spain.
