El Mac began painting both smaller indoor works as well as public murals and graffiti in Phoenix in the mid 1990s, and since that time has developed his unique visual aesthetic and rendering style which utilizes repeating contour patterns. He is best known for his meticulous paintings and large-scale murals exploring feminine beauty and honoring ordinary, overlooked, or marginalized people. He has been commissioned to paint all over the world for museums, universities, and cultural institutions, including the Groeninge Museum (Belgium), San José Museum of Art (California), Northeastern University (Boston), University of California (San Diego), QAGoMA (Brisbane), Fondazione PRADA (Italy), and the Mexican Secretariat of Foreign Affairs, as well as murals in Belgium, Cambodia, Cuba, Denmark, England, Germany, Ireland, Morocco, Puerto Rico, Singapore, South Korea, Spain, Sweden, and Vietnam.
