Mr Greg James

Consultant Neurosurgeon


Greg James is a Paediatric Neurosurgeon with clinical and research specialisms in craniofacial surgery, cerebrovascular surgery, complex cerebrospinal fluid (CSF) disorders, stereotactic radiosurgery and head injury.  

His surgical philosophy is built on three tenets: 

  1. Excellent surgical technique - augmented by the most advanced technology for safety and efficacy 

  1. Teamwork - with high volume, subspecialized multidisciplinary groups such as the Great Ormond Street Hospital Craniofacial Unit and Neurovascular Team 

  1. Open, honest and full communication with children and families at all stages of their clinical journeys. He encourages families to contact him directly with questions and values open discussion about the pros and cons of surgical decisions. 

In addition, he strongly believes surgical and academic excellence go hand-in-hand and regularly presents and publishes research internationally, as well as holding multiple local and national neurosurgical training roles. He is honorary Senior Lecturer at University College London, as well as honorary Consultant Neurosurgeon at the National Hospital for Neurology and Neurosurgery.
