Hear it From A Few
Of Our Clients

  • I can't thank Ernie enough for investing his time and sincere efforts to helping my family out. He truly is a master of his craft.

    “A few years back, Ernie Castillo represented a family member of mine who was charged with a vehicular offense. Although minor compared to the high profile cases Ernie is accustomed to, Ernie took the case with the utmost professionalism and was able to reduce the charge so that my family member's record was not affected. I can't thank Ernie enough for investing his time and sincere efforts to helping my family out. He truly is a master of his craft.”


  • I would highly recommend Mr Castillo to anyone.

    “Mr Castillo represented me on a criminal case in which I was falsely accused in 2012. He took over the case from a previous lawyer who was less aggressive and not actively pursing my defense. Mr Castillo is a confident, aggressive and very persistent lawyer. He kept my family and I up to date on the case and also returned our calls on time. Mr Castillo persuaded me not to take any deal and wanted take the case to trial because he was confident that he would win. With the Lord's guidance and Ernie's aggressiveness my case was dismissed. I would highly recommend Mr Castillo to anyone.”


  • I would recommend Mr. Castillo without any reservation.

    “Ernie Castillo was highly recommended to us. I researched and interviewed a few attorneys before making a decision of who we were going to select. It's so tough selecting when you're skeptical with the horror stories of attorney's not feeling the passion for their work but the money. After long conversations my husband and I decided to go with Ernie to represent our son in a serious case with multiple charges. We were not disappointed at all. Mr. Castillo expertise exceeded our expectations. His was thorough, he kept us up to date on the case, answered all our questions, returned our calls in a timely manner, he's truly a genuine and sincere person. Most of all his knowledge in handling the case was remarkable. I can't express thanks enough to Ernie for the spectacular job he did defending my son who was facing years in jail. He took a stressful situation and relieved it with a positive outcome. I would recommend Mr. Castillo without any reservation.”
