The relative pronoun quien(es), meaning who and whom, refers only to persons and is commonly used as an indirect object or after a preposition. Use que to express who or whom unless the phrase is set off by commas or introduced by a preposition. (Note that you will never end a sentence with a preposition in Spanish.)
