  • Josh D Lee

    Mr. Barba is one of the new breeds of lawyers known as the lawyer-scientist. When defending a person accused of driving under the influence it is imperative that the lawyer have a deep understanding of the science behind blood and breath testing. Very few lawyers spend the time necessary to be a lawyer-scientist. Mr. Barba has and does. You are in good hands with Mr. Barba representing you on an alcohol related charge.
