She not only created the first educational facilities in Uruguay to teach those with disabilities, but she developed job placement programs and parent support groups to help children integrate into the larger society.

She studied to be a teacher, graduating in 1941 from the Instituto Normal María Stagnero de Munar,[2] Her first job was in Isla Patrulla and after a few months there she transferred to Santa Clara, where she first encountered developmentally delayed students.

She began working with Dr. Emilio Mira y Lopez in 1945 at the Laboratory of Psychology researching "marginal cases" and was awarded an authorization to perform professional guidance counseling for schoolchildren.

[3] From 1945 to 1946, she worked in the Marlboro Psychiatric Hospital in New Jersey and simultaneously at the International Institute of Education (1945-1947), receiving a certificate of mastery of Mental Hygiene and Abnormal Children's Organizational Services.

The focus was on information, and sharing of experiences, because even the medical community did not know what caused a lot of the developmental delays or what the learning capacity of the children was.

[13] That same year she launched a public awareness campaign hoping to build an infrastructure of care, integration, protection and support for people with disabilities.

She founded the Asociación Nacional pro NiñoRetardado Mental (ANR) to promote the general welfare and development of programs and research to benefit developmentally disabled people.

[15] García began working with the Organization of American States Inter-American Children's Institute (IIN) in 1966, as the head of the Special Education and Early Childhood Division.

In 1988 she was honored by the OAS with the Andrés Bello Award for her regional contributions to the education of disabled people; that same year she was awarded a medal from the Government of Ecuador for her efforts in special education; and the following year the University of Kansas created a scholarship through the Bureau of Child Research in her name, which is granted to professionals wishing to study early intervention and stimulation.

The Uruguayan government renamed the Educational complex of Special Schools Nº203 and 280 in Montevideo after her in 1994 and in 1995, she received the Royal Association for Prevention and Care of Persons with Disabilities Reina Sofia Award for Rehabilitation and Integration in Madrid in 1995.
