I have tried many of these cases and the most valuable asset when I do is Dr. Pierce. He has testified in many of my cases with the outcome being
      the two word verdict my client so badly needs. The most clear and concise witness I have ever used. I have come to the point where I feel the only way to be truly effective is to have him on our team when we go to trial. He is approachable, understanding,
      and infinitely knowledgeable.

    <h1 style = "text-align: center;  text-align:justify; font-family: avenirnext; font-size: 20px; line-height: 1.5em; color: #54595F;">Dr. Pierce is my ONLY expert for child abuse cases. He is a national leader in understanding false accusations based on fear of the boogey man/family dynamics/hyper-sensitivity to touching based on past trauma. I have been doing sex defense work for
      20 years. Dr. Pierce is the expert I rely on to help me understand the intricacies of my cases. He is a straight shooter. And perhaps more importantly, he speaks very well to juries in common language which is clear, concise, and not elitist. I
      have 5 cases pending with Dr. Pierce and have yet to lose one where he has consulted/testified.
