Lisa Loomer is an American playwright and screenwriter who has also worked as an actress and stand-up comic. She is best known for her play The Waiting Room (1994), in which three women from different time periods meet in a modern doctor's waiting room, each suffering from the effects of their various societies' cosmetic body modification practices (foot binding, corsetry, and breast implantation). She also co-wrote the screenplay for the film Girl Interrupted. Many of her plays deal with the experiences of Latinx and immigrant characters. Others deal with social and political issues through the lens of contemporary family life. Beyond that, Loomer's play The Waiting Room discusses issues such as body image, breast cancer, and non-Western medicine.
