"All the webinars that I ordered were excellent, taught by high quality instructors. Each one addressed some (important technical) gaps. I was able to apply content from 'How to be an Effective Expert Witness' right away. It contains a wealth of information from beginning to end. I think it would appeal to many people from multiple technical disciplines who may testify in court."
