Drama at Lo-Ellen Park covers a large range of curricular and co-curricular activities. The Grade 9 developmental drama course tries to ensure that students enhance their self-confidence and self-esteem while improving their problem-solving skills through constant group activities that are as entertaining as they are challenging. Students have the opportunity to work with tableaux, pantomime, improvisation, monologues, dialogues, script work, and scenes. Senior drama classes go deeper into character development and play production, and many of these plays are presented for the school community.

The LEP Theatre Company, through its Musical Theatre credit course, has been presenting large-scale musical productions since the mid-1980s, and people are always impressed by the polished professionalism of these productions. Some of the most popular and influential shows in the history of Broadway have been presented to great acclaim. Musical Theatre students also present an annual variety show of skits, sketches, songs, and dance numbers. The Variety Show plays to packed houses every fall.
