Recommended Paediatricians

[Osospecial1]

Hi all, could anyone recommend a Paediatrician who specialises in ASD/ADHD please? Preferably around Cardiff or London. I have previously seen Dr Daphne Keen to diagnose my daughter when she was around 4yrs old and found her very good. She is now 7 and we don't have a local nhs paediatrician, haven't for years (and to be honest they were never much good when we did) Id like to see a specialist for general advice on a few different things that a gp just cannot answer. Can anyone help? I've googled a bit and Dr Stefan Studnik came up, anyone have any experience of him or any others you can recommend please? Thanks
