Maria Canals Barrera (born September 28, 1966) appeared on George Lopez as Claudia Palmero, the deceased mother of Veronica Palmero, Angie's niece, who granted power of attorney of the trust fund of her daughter to George through her videotaped will, who could then grant the inheritance to Veronica only if he deemed her to be responsible enough to inherit it in the Season Five episode "A Funeral Brings George to His Niece" (episode #15). Maria is perhaps best known for her rola as Theresa Russo on the Disney cable network series Wizards of Waverly Place.
