Afterwards, he attended San Diego State and graduated with a BA in 1974. Ochoa became involved with Chicano activism while he was in college. In April 1970, he saw fliers at the City College Student Center for a park take-over for what would later become Chicano Park. Ochoa recalls leaving class to go to the protest. He and other artists added their own stamp to the protest by starting murals on the park. Along with Guillermo Aranda, Mario Acevedo, Tomas Casteneda, Salvatore Borjas, Ochoa began painting the retaining walls and pylons near Logan Avenue, claiming the park for the neighborhood. As the park was recognized by the city, Ochoa continued to help improve the art and the organization of Chicano Park. He later became part of the steering Committee for Chicano Park. Ochoa has continued to be involved with the park and its restoration, including writing a manual for how to restore the murals. Ochoa was part of the founding group of the Centro Cultural de la Raza called Tolecas en Aztlán. to. As controversy surrounding the creation of the Centro in Balboa Park escalated, Ochoa became a key negotiator during the protests. Later, he served as a director for the Centro from 1970-1973 and again from 1988-1990. Ochoa has been teaching in many different capacities throughout the years. He states that he never wanted to be a full time teacher, but when his son was born, he was wanted to ensure that he had a steady income. Ochoa has taught at the MAAC Community Charter school for 13 years and retired in 2014. He taught at Grossmont College for about 23 years. Ochoa also taught at UCSD and San Diego Mesa College. Many of his teaching jobs had a community function, like when he worked with youth to create murals with a grant from the Jacobs Foundation in the Diamond Neighborhoods located in southeastern San Diego. Ochoa and other artists would bring free paint and work on the area surrounding Chollas Creek. The program was named Graff Creek. His teaching youth how to paint decreased the amount of graffiti the neighborhood received. He worked as an art consultant for the Jacobs Foundation for 11 years. He has since retired from formal teaching, but plans to continue to paint and work with children's art classes and workshops. He has a son, Victor and a daughter, Xochitl. Ochoa has always felt that public art, like murals, is a very important teaching tool for members of his community.
