Torvin was a Trill doctor living on the planet Trill in 2371.

When Jadzia Dax returned to Trill in that year to find out the cause of her strange hallucinations and she was having major difficulties, Doctor Renhol asked for Doctor Torvin to prepare a new host for surgery. Benjamin Sisko instead recommended to tell the doctor to get himself a cup of raktajino as he wouldn't be needed. (DS9: "Equilibrium")
