Getting to know Mr Alexander von Roon…
When not at work, he tries to spend time with his two boys, who are starting to beat him at table tennis with alarming regularity. He keeps fit and is passionate about cooking, wine, travel and, occasionally, windsurfing. He has taken up playing the piano again recently and is grateful to his family for their forbearance with his efforts!
“I joined OneWelbeck Digestive Surgery because I was very excited about the opportunity to be engaged as a clinician in the development and design of a state of the art diagnostics and day surgery centre from the very beginning. There is a uniquely collaborative spirit at OneWelbeck which in my opinion is unrivalled in private or public healthcare in the UK. As a group of clinicians, we are empowered to bring our many years of collective experience at the frontline of delivering healthcare to bear in the design process. As a result, we have been able to build excellence, beautiful design and efficiency into every step of the patient journey through OneWelbeck.”Mr Alexander Von Roon
