Mr Apostolopoulos is a Consultant Neurosurgeon sub-specialising in brain tumour surgery. He completed his neurosurgical training in London.

During the period of his neurosurgical training he also completed his Doctorate Degree in real-time navigation for brain tumour surgery at Imperial College London.

On completion of his neurosurgical training he was appointed as a Senior Fellow at the prestigious Royal College of Surgeons Fellowship in Brain Tumour Surgery at Southampton University Hospital, which he completed in June 2015. He was awarded the Royal College of Surgeons Certificate in Brain Tumour Surgery.

Since October 2015 he has been a Consultant Oncological Neurosurgeon at the world famous John Radcliffe Hospital in Oxford.

Mr Apostolopoulos has performed more than a 1000 brain tumour operations, has enormous experience in awake surgery and he is amongst the surgeons with the highest number of awake operations/year in the UK.

To enhance his surgical results apart from the usage of state of the art brain navigation, intraoperative ultrasound, and intraoperative neurophysiology he also collaborates with a great team of professionals with enormous experience in complex brain tumour surgery (surgeons, anaesthetists, neuroscientists, neuroradiologists).

He has been faculty in national and international courses in brain tumour surgery and intraoperative navigation for brain tumour surgery.

He carried out research on advanced real-time intraoperative brain navigation needed to carry out safe brain tumour surgery. He is currently involved in national and international research looking to improve the outcomes of patients with brain tumours by applying novel treatments.

He contributed in writing chapters in Neurosurgery textbooks, and he is involved with the teaching of the Oxford medical students on a regular basis.

The great results of his work are based not only on the technical aspects of the operations, but also on his meticulous approach for every aspect of the overall management of his patients. He is also a believer that the outcome of any treatment can be further enhanced by sincere and friendly communication with the patients and their families.
