- Family Reunited— In 2011, Deirdre helped reunite a Mexican couple with their U.S.-born daughters after the parents were deported to Mexico and Chester County Children Youth and Families sought to terminate their parental rights. Since the parents could not travel to the United States to testify, Deirdre arranged for them to appear in court via Skype™ (online conferencing). The case was widely covered by the media as the first use of such technology for testimony in U.S. courts. In July 2011 the parents were awarded custody of their daughters. The children were brought to Mexico where they were reunited with their parents.
