Associate Artists

Heartbeat Opera consists of an ever-growing, ever-deepening company of artists. Our Associate Artists are frequent collaborators who have played essential roles in defining our company and creating our body of work. We recognize their extraordinary contributions and commitment. Associate Artists do not necessarily work on every Heartbeat project, but they do take an ongoing, active interest in our growth.
