VISION: The Harlequin Theatre Guild, the only representative of the University where theatrical interests and rights are concerned, is guided by the Lasallian values. It envisions itself as a college-based theatre group that produces original Filipino works and stages local and Filipinized foreign plays relevant to the Lasallian academic community. It prides itself with premium theatrical productions while advocating Religio, Mores, and Cultura through service and social awareness.

MISSION: The Harlequin Theatre Guild exists as the revelation of the Lasallian community to social issues while interleaving fine theatrical performances. The guild acts as the nurturing place of gifted artists while carefully balancing the academics and art. It inculcates discipline and professionalism among its members through thorough trainings and workshops. The guild also promotes the distinctive Philippine culture in line with the Cultural Arts Office’s goal of advocating culture and art as key factors in the holistic development of an individual. The guild performs for the audience but continually serves God.
