In 2380, Captain Carol Freeman ordered her daughter, Ensign Beckett Mariner, to undergo therapy with Dr. Migleemo. He noted the frequent examples of insubordination in Mariner's report, and suggested that she make paella as a means of channeling her rage. (LD: "Crisis Point")
In 2381, when the bridge crew were discussing the Collector's Guild, Captain Freeman mentioned that the collectors all tried to collect Data. Migleemo regarded this with sadness, as he cried and asked why they could not simply leave Data alone, as he "just wanted to feel."
Later that same day, after the away team returned to the Cerritos from their away mission on Kerner Hauze's starship, Migleemo found Lieutenant Kayshon, who had been turned into a puppet, in sickbay. Migleemo contemplated using Kayshon for puppet therapy, but he was prevented from doing so by Dr. T'Ana, who told him to acknowledge the sign on Kayshon's biobed stating not to play with him, as he was not a real puppet.

Migleemo was voiced by Paul F. Tompkins.
