Graduated in Chemical Engineering with 22 years of professional experience in Refining and Petrochemistry and 17 years of academic experience in universities and high schools. Classes only in Spanish.

From my personal experience with Waldo during my degree I could learn a lot with him about the chemical basis and and the on industry field because it's a person who has a big experience in the chemical industry and has also vocation to teach in different ways with the best attitude. I really respect him because it's kind, friendly, dedicated and passionate talking about his work. Then because of that I consider Waldo would be a key person in any organization.

I confidently recommend Professor Waldo Urribarri, who was my professor in Natural gas Processing, Industrial Chemistry and Chemical Technology back at the university, and most recently in The Petroleum Refining Indutry course. He is articulate and his teaching material is based on recognized theoretical foundations, adding current knowledge on the subject, which is of most interest in the current times we are leaving. In addition to the above mentioned, his reception was always excellent and he clarified all my concerns promptly. This is due to his vast experience in the oil refining industry and natural gas processing fields, both in terms of technical issues and industrial projects.
