Our Doctors
Sleep Testing Australia boasts a network of independent sleep scientists and sleep and respiratory physicians that provide sleep testing oversight, review and specialist consultation with our patients. This is an important distinction as the scientists and doctors are not employed by Sleep Testing Australia. This ensures independent governance of scientific analysis and medical review of sleep studies that form the service.
Our independent network of doctors are also available for consultation should your GP feel the requirement for specialist involvement in your sleep health.
