Altrecht is an institution for secondary-level mental health care. Altrecht welcomes patients from all sections of society. All caregivers at Altrecht are expected to be able to provide good and effective care to all patients, irrespective of their cultural and religious backgrounds. Altrecht has an in-house centre of expertise concerning cultural psychiatry and recruits people from various cultural backgrounds. Referral to Altrecht is only possible by official health care professionals such as general practitioners, bureaus for child and adolescent welfare, independent psychiatrists, psychologists, psychotherapists and other institutions (for example the PAAZ). Registrations will initially be processed by Altrecht Entre, which is the entry point for the entire institution of Altrecht (with the exception of crises, the justice system and Top ggz).
