San Antonio Criminal Defense


About Us


I worked in the criminal justice system in England, as a police officer, for fifteen years. I moved to San Antonio and became a United States citizen in 2014. I have worked as a prosecutor and now work in the criminal justice system in a different capacity—as a criminal defense attorney. I truly believe that the United States is the land of second opportunities. I want to help you get your second chance.

My experience within the criminal justice system has helped me to develop excellent communication and advocacy skills. These skills led to me developing strong values of service, loyalty, discipline, and attention to detail. These skills continue to serve me to this day. I will use these skills to serve you. My passion, drive, experience, and dedication to standing up for people facing injustice and inequality will make you glad you chose me to stand up for you and to stand by your side.
