As an AI language model, I do not have access to information about individuals. However, I can provide you with general information about the controversial organization NXIVM. NXIVM was a self-help and professional development organization that was founded in 1998 by Keith Raniere and Nancy Salzman. The organization was based in Albany, New York. However, the organization was exposed as a cult that engaged in various criminal activities. Keith Raniere was convicted of multiple charges, including sex trafficking, racketeering, and conspiracy. Many high-profile individuals associated with NXIVM, including actress Allison Mack, were also arrested and convicted. The organization has since been disbanded, and its leaders are currently serving prison sentences.
