Can teach all schedules night or day. Born and raised in Chile, studied Architecture at the best university there, was an architect in Chile for 5 years, doing commercial banking. Lived in Houston TX for decades, was an exporter of MRIS's to small & large Latin American corporations plus all the american/japanese/german auto makers manufacturing there. Very well versed in high level spanish as in technocracy, politics, art, science, economics, science, philosophy, lifestyle, religion, engineering, etc, and decision making narratives. But I can teach any level for simple lifestyle purposes as well.
