Louise Williams studied violin at the Royal Academy of Music with Manoug Parikian and at the Juilliard School in New York with Ivan Galamian. She then became a founder member of the Endellion Quartet as its second violinist. After five years, she left music for a while to study organic horticulture in England and meditation in India. On her return to music she switched to viola and joined the Chilingirian Quartet, where she remained for five years until the birth of her three children. Despite working part-time since then, she was a member of the Raphael Ensemble and is currently in the Frith Piano Quartet.
