Sebastian trained as a paediatrician in Germany and is a European Specialist in paediatrics. After a year in paediatrics in the UK he underwent a second specialisation in audiovestibular medicine, which he finished in 2004 after having also completed a Masters in the field in 2003.
He lead a North Central London Service for the Royal Free London for 16 years, but alongside it worked also at the Royal National Ear Nose & Throat Hospital (UCLH). Since 2020 he has consolidated his NHS work at Great Ormond Street Hospital.
Outside of medicine, his passions are spending time with his 2 daughters and sailing an old wooden Mirror dinghy.
And his Twitter feed, of course.
