Telnorri was a male counselor aboard Deep Space 9 in the 2370s. In 2372, Telnorri counseled Miles O'Brien after O'Brien experienced twenty years in prison as part of an Argrathi mind altering procedure. O'Brien was initially to see Telnorri for three counseling sessions a week, although after a series of outbursts and not attending Telnorri's sessions for at least ten days, Benjamin Sisko ordered O'Brien to see him daily for as long as Telnorri thought necessary. O'Brien was irritated by Telnorri's discussions on life in the simulated prison, the number of beatings he received and if he was distressed by the lack of toilet facilities. After contemplating suicide, O'Brien agreed to see Telnorri again. (DS9 episode: "Hard Time")
