Specialized Services

Dan Herrin is recognized as a Court Qualified Expert in the controversial and often confusing area of U.S. Sentencing Guidelines.

For seven years, Dan Herrin completed exhaustive investigation reports for the U.S. District Courts of Alabama and Mississippi, where he worked on some of their highest profile federal criminal cases. These reports consisted of comprehensive information on each defendant's social, criminal, and financial history necessary to calculate their ultimate sentencing range.

Today, Dan Herrin consults with attorneys regarding these matters and provides expert testimony when necessary. In the internationally publicized trial of a defendant known in the press as "the world's largest marijuana dealer," Herrin's testimony played a crucial role in the defendant's acquittal on the substantive charge.
