Jenzo was an Earth-based counselor and a colleague of Deanna Troi. In 2376, as the USS Enterprise-E was seven light years away from Jupiter Station, Troi suggested to Reginald Barclay that she could refer him to Jenzo instead of attempting to counsel Lewis Zimmerman long distance. Barclay, however, wanted "the best", and declined her offer, preferring her advice to anyone else's. (VOY: "Life Line") This character was only mentioned in dialogue.
