  • Christopher Michael Villasana

    Having observed and interacted with Spencer in the courtroom, I endorse him as one to seek out if you desire competent and thorough representation of your legal needs. Spencer may not always tell you what you want to hear, but he will provide you with an accurate assessment of your situation as well as your available options to resolve your matter. Often defendants have a misconception as to what is really in their best interest. Spencer works with you throughout your case to protect your legal interests.
