Sarah Edmondson, a Canadian actress who had been an ESP participant since 2005, said that she left the group after Mack inducted her into DOS the preceding March at her Albany house. Edmondson alleged that participants were blindfolded naked, held down by Mack and three other women, and branded by NXIVM-affiliated doctor Danielle Roberts, using a cauterizing pen. (Edmondson subsequently filed a complaint with the New York Department of Health against Roberts, but the agency replied that it lacked jurisdiction because the alleged actions did not occur in a doctor–patient relationship, and advised Edmondson to report the matter to the police. [better source needed]) Appearing on an A&E show about cults, Edmondson would provide additional context on the use of the "collateral" concept, stating that it was used in innocuous forms from the earliest, outermost stages of NXIVM in order to acclimatize victims—for example, collateralizing small amounts of money that one might forfeit if one did not go to the gym one day. The Times would later report that "hundreds" of members left NXIVM after Edmondson went public about her experience.
