Leah is a British-Indonesian immigrant who moved from England to the United States in 2016. As a psychiatric survivor, childhood domestic violence survivor, former foster youth, and a person who has previously experienced homelessness, Leah is working towards a world free of oppression and injustice. She believes that promoting psychological and social approaches to psychosis is equity in action towards this vision.

Trained as an Occupational Therapist, Leah primarily worked in clinical mental health settings until she came to the United States, where she found a home working in nonprofit leadership. Leah has worked in an array of settings with people diagnosed with psychosis, including working in early intervention in psychosis, assertive outreach, a mental health recovery café, a high-secure forensic hospital, and homeless emergency shelters.
