I am a migrant who has learned and understood the needs and difficulties of my community and the limitations they face to sustain active participation in sports. I am interested in promoting academic success combined with the physical and emotional well-being of my community. I discovered that futbol is the opportunity for achieving these goals.” Noemi is a compulsive cook and baker, she loves guacamole, salsa and doing outdoor activities with her three daughters, biking and camping are her favorites.
