Grossmann’s collage elements include her collection of found photographs that become a catalyst for her works in oils and mixed media on paper. Curator Martha Langford states in her text, Image & Imagination, that adolescence struggles in the "large-as-life figures whose postures and gestures express feelings ranging from solidarity and isolation, shyness and impertinence; the excitement of transformation, as well as fear". Her Alpha Girls series grapples with issues such as the disappearance of childhood as teenagers are targeted with media/ popular culture enforcing the premature sexualization of young teenagers. Robin Laurence in his Georgia Straight article, Girls Caught in Market’s Tide, states that in Grossmann’s young girls, "innocence plays again knowingness, confrontation against seduction, individuality against conformity.
Grossmann’s past series of works have included themes of imprisonment, war and the Holocaust. Grossmann first received attention as part of the Vancouver Art Gallery’s 1985 Young Romantics exhibition. She has exhibited extensively for the past fifteen years throughout Canada, the US and internationally.
