Guzman is one of seven children of Mexican immigrant parents. She was raised in Houston, where she graduated from the predominantly Hispanic Stephen F. Austin High School in 1979. Now a resident of Cypress in Harris County, she is the first Hispanic woman to serve on the Texashigh court. Another Hispanic, David Medina, was elected to the court in 2006 and served until 2012, the year he was defeated by John P. Devine in the Republican primary run-off for re-nomination to his supreme court seat. Guzman was recognized by the Hispanic National Bar Association as "Latina Judge of the Year" and as "2009 Judge of the Year" by the Mexican American Bar Association of Texas Foundation. At the time of her appointment to the supreme court, Perry called Guzman a "principled conservative with an "unmatched work ethic."
