Our story
Before she became a lawyer, Cynthia Mazariegos already knew the immigration system from the other side: the side of the families living through it. As a first-generation Guatemalan American, she understands what every form and every wait means to the people behind them.
That is how we work at Grupo REU: we explain every step in plain words, in Spanish or English, and we charge fair fees. Since 2017 we also handle family law, because the two so often go hand in hand.
