Big thank you to for bringing an ice cream truck to my office. We've been doing business with Sanctuary for many years. When we have clients facing six and seven figure bail bonds for very serious offenses, it's important that they hire a law firm that has a good working relationship with a reputable bail bondsman. When people are facing serious felony offenses, they trust the largest exclusive criminal defense law firm in Arizona to fight for them.
