In 2011, she became as a youth volunteer for Techo to fight extreme poverty in Latin America, by constructing transitional housing and implementing social inclusion programs. In 2013, she was hired as Local Director for the volunteer team in Monterrey which, under her leadership, became one of the most recognized volunteer teams in the city.
