She was the daughter of Luisa Teresa de Montemayor Núñez and Dr. Andrés Pietri Méndez, an otorhinolaryngologist and the founder of the Simón Rodríguez Benevolent Institute.

She was also the niece of Luis Gerónimo Pietri Méndez, who held the positions of Minister of the Interior and Governor of the Federal District during the governments of Eleazar López Contreras and Isaías Medina Angarita.

Upon her husband's victory in the 1968 Venezuelan general election and her role as First Lady, she continued the work initiated by her predecessor, Carmen América Fernández Alcalá, in the presidency of the Children's Festival Foundation.

Other additions were the "Week of Art and Culture for Children", the "Pages for Imagination" editions, "Pocket Parks", and the educational television program Sopotocientos, among others.

The museum became a trailblazer in Latin America and served as a mentor for similar institutions established later in the region, including in Colombia, Argentina, Mexico, and Puerto Rico.

Additionally, she initiated the "A Fondness for My City" program, a public-private partnership aimed at revitalizing green spaces and public squares in Caracas.

At the end of her husband's second term on February 2, 1999, Alicia Pietri withdrew from public life and returned to her home in Tinajero, located in the Los Chorros neighborhood of Caracas.

Instead, she tirelessly advocated for the rights of the most underprivileged children," states the biographical review found in the book "200 Venezuelan Educators: 18th to 21st Centuries" (2016), published by the Empresas Polar Foundation and Andrés Bello Catholic University.
