Rob Parrish began his legal career in the Utah Attorney General's Office in 1980. In 1983, after representing the Utah Department of Public Safety as its sole counsel and presenting criminal appeals before the Utah Supreme Court, he became a prosecutor and managed trials of all kinds before specializing in child abuse prosecution in the late 1980s. Parrish has worked on both child protection cases and criminal cases involving proof of child abuse issues. He has successfully prosecuted child homicide cases that other people considered to be impossible. Because of his efforts, he has been nationally and internationally recognized as an expert on proving the medical aspects of all forms of child abuse in a court of law. One of his primary strengths is explaining complex medical concepts to an audience of laypersons.

While deputy director of the National Center on Shaken Baby Syndrome from July 2000 to 2002, Parrish consulted on hundreds of cases all over the world, authored a training curriculum for law enforcement and CPS investigators, and wrote articles and chapters for several prosecution and medical texts. He coauthored a CD-ROM that visually presents the medical issues in Shaken Baby Syndrome using diagrams, computer animations, and text. Parrish has presented training in England, Australia, and throughout the United States on a variety of topics relating to abusive head trauma in children and focusing on the legal system's role in responding to this severe form of child abuse. He continued to prosecute difficult cases of shaken baby syndrome in collaboration with local prosecutors in Utah through 2001.

In 2002, Parrish returned to state government as a Guardian ad Litem, representing abused, neglected, and delinquent children in juvenile court and managing six other attorneys and staff. He is coeditor of Abusive Head Trauma in Infants and Children: A Medical, Legal, and Forensic Reference, which was published by G.W. Medical Publishing in July 2006.
