A residential treatment center in Missouri advertises to adoptive parents that it can help heal struggling children. Calo Programs is part of the so-called troubled teen industry that has been quietly institutionalizing adopted children at extraordinarily high rates. How Calo makes money and what happens to kids there offers a window into a larger phenomenon. Some youth treatment centers depend on government funding despite limited oversight. Calo is facing more than a dozen lawsuits and parents describe a chaotic environment that left their children more traumatized than before. Calo denies wrongdoing and says its treatment has helped many children.
