Fernando worked for a short period of time in the Oil Fields of Ecuador, Peru, and Brazil. He came back to America in 1974, and went to LSU to study Chemical Engineering.  He worked for three oil companies, and retired from Murphy Exploration and Production after 25 years of service with Murphy in July 2005.  Throughout all those years he resided in New Orleans a City that he promised himself that he would never leave.


August 29, 2005 “Katrina”.  Newly retired, Fernando dedicated his time to reconstruct his house.  He noticed that there were a great number of Latin American people working in the New Orleans area cleaning, and rebuilding.  Fernando thought he could volunteer, assist, and translate for people within the Latin community.  Eventually Fernando was hire by the Louisiana Department of Health and Hospital.  That is how a new carrier came to Fernando. He has been working in the community for about 10 years with different agencies including Louisiana BEST, Children’s Bureau of New Orleans, and at present for Tulane University as a Community Health Worker.  Fernando still volunteers in different capacities any time he has an opportunity.


Somewhere between all those years he married a beautiful girl from Colombia, and had three wonderful boys of whom Fernando is a very proud.  He is the father of three son Fernando, Michael and Javier.  Proud Grandfather of two handsome boys Oscar and Nicholas of Chicago, IL, three Grand-dogs, and one Grand-cat.  We do not think Fernando is planning a full retirement for at least the next 20 years.
