He has also accompanied critically acclaimed artists, including Steven Sandoval, Shaila Dúrcal, Lupita Infante, Ana Bárbara, Yuri, Beatriz Adriana, Juan Valentín, Leo Dan, and many others.

Garibay is a pioneer in mariachi education. Under the mentorship of José Hernández, the director of Mariachi Sol de México, Garibay became one of the founding teachers of the José Hernández Mariachi Academy. This experience led to his appointment as Orange County’s first full-time mariachi director. He currently serves as the director of Santa Ana College’s Mariachi Dons, CSU Fullerton’s Mariachi Titans, and Chapman University’s Mariachi Panteras, all of which are Orange County collegiate ensembles.

Garibay also owns and directs three professional mariachi groups in Orange County. His company serves as a bridge between student musicians and the professional mariachi industry, offering a pathway for student artists to become professional mariachis.

In addition to his commitments in Southern California, Garibay is collaborating with the Davis Joint Unified School District and UC Davis as their mariachi director to establish a citywide mariachi program in Northern California.
