Missionaries to the Preborn is an American pro-life advocacy group based in Milwaukee, Wisconsin. It was founded in 1990 by Rev. Matthew Trewhella. This organization, as visible in names and faces of their membership, is closely tied to the Faithful Soldier School of Evangelism, which is run by his son-in-law, Jason Storms.
In June 2005, the group held a nine-day campaign in Michigan, dubbed the "American Atrocity Tour". The group is known for displaying signs featuring graphic photographs of aborted babies along roadsides.
Trewhella has served 14 months for blockading clinics. In 1994, he was a featured speaker at the U.S. Taxpayers Party convention. He has expressed non-condemnation of those involved in abortion-related violence, stating, "I don't condemn people who use force to try to protect babies, because they are human beings. And if someone uses force to try to protect those babies, it would be as if someone used force against Dr. Mengele, from Adolf Hitler's era. If someone used force against him, would I condemn the person for stopping Mengele from all the atrocities he did? No, I wouldn't condemn that person". However, he tempered these remarks by claiming that he does not advocate violence.
Trewhella currently hosts a weekly television program in Milwaukee, called "In Focus."
