Para nosotros, la familia es la célula principal de la sociedad, es donde se aprenden los valores y la práctica de éstos constituye la base para el desarrollo y progreso de la sociedad. Es, quizá, el único espacio donde nos sentimos confiados, plenos; es el refugio donde nos aceptan y festejan por los que somos, sin importar la condición económica, cultural, intelectual, religión a profesar o preferencia sexual. La familia nos cobija, apoya, nos ama y respeta.
