Welcome to my website.

This website is a private website for the practicing criminal defense attorney. DUI cases constitute the primary focus of the information contained in the website but any criminal case involving alcohol, drugs, Standardized Field Sobriety Tests (SFST’S), closed head trauma or any other neuro-psychiatric issue may be addressed.

Contained within the website is a collection of my intellectual property of PowerPoint slides, custom animations, recorded presentations, and answers to relevant technical questions and is available for each attorney to learn from and to add to their own knowledge base, and for use as demonstrative aids in any case we are working on together.

This website requires registration by the criminal defense attorney and an understanding and agreement to follow the website conditions.

The conditions for registration and membership are simple.

  1. Your membership is free.
  2. You are a current practicing criminal defense attorney in good standing with your state bar association.
  3. An invitation from me to join.
  4. Your membership and the website and the website contents are not to be used by anyone else without my express written permission.
  5. My intellectual property is not for sale or distribution, but it may be used in a specific case we are working on together.
  6. I may terminate anyone’s membership at any time for any reason.
  7. The Question & Answer Forum (Q&A Forum) is not a discussion board, it is designed to answer a specific question about a given issue in a criminal case. Your question should contain enough information for me to consider the issue and respond with an appropriate answer, and references if necessary. Many responses require considerable thought and research. Often they are repetitive, so a simple search of the Q&A Forum may reveal the same question already answered. Searching the Q&A Forum before asking a question is therefore encouraged.
  8. Anything I share or suggest is based on hypotheticals or assumed facts supplied to me by the person asking the questions, and no one may rely on them for the purposes of imposing liability or of seeking damages. No warranty of correctness or accuracy is made by my giving my input about anything posed to me. I merely suggest an opinion based on matters supplied or told to me.
