Dr Stefan Studnik is Consultant Paediatrician with long experience in Autism, ADHD and other developmental problems, based in St Marys Hospital, Paddington, London where he has built up a multidisciplinary team for Autism including Paediatrics, Speech & Language Therapy and Clinical Psychology.

Dr Studnik’s service is designed to meet the recommendations of the National Autism plan. We are now able to diagnose Autism earlier and help families to access help sooner. Families routinely give positive feedback to the team. As part of this services development, Dr Studnik also has trained referrers in screening and early detection of Autism and has facilitated training for the multidisciplinary team in diagnostic tests.

The service works across disciplinary boundaries to include Child Psychiatry, Education, Social Services and Charities.

Dr Studnik also has regular clinics to see these children jointly with Child Psychiatrists. Stefan Studnik is a Honorary Senior Clinical Lecturer with Imperial College, London and is actively involved in undergraduate and postgraduate recruitment, teaching and examination.
