Hilda Roberts competed in the arts competition at the 1932 Los Angeles Olympic Games, one of eight Irish artists who entered nine exhibits in the painting competition staged at the Los Angeles Museum of History, Science and Art from 30 July to 31 August 1932.

Roberts studied at the Metropolitan School of Art in Dublin. She worked as a portrait painter but also created illustrations, drawings, embroideries and sculptures.

Roberts married Arnold Marsh, the headmaster of Newtown School, Waterford, in 1932 and was involved in setting up the Waterford Art Exhibitions, which later led to the establishment of a permanent art collection in Waterford City.
