Gabriela Peña's family believes some teachers may just be born with a special gene. Her grandfather, aunts and uncle all became teachers working in Mexico and the United States, she said. Peña, a Los Fresnos and Houston native who has been working at Harlingen High School for eight years, received the Claes Nobel Educator of Distinction award from the National Society of High School Scholars, an international organization that recognizes academic excellence at the high school level in over 120 countries.
