Welcome to Mary L. Welty Elementary School, home of the Roadrunners, where our motto is “Doing Your Best Every Day!” We are located about an hour south of Tucson in the beautiful mountains of southern Arizona in Nogales, just north of the Mexico border. Our highly qualified teachers and caring staff work hand-in-hand with the supportive families in our surrounding community. We serve our kindergarten through fifth-grade students with pride.
