‘Dr Nicolas Priestley has been my professional colleague for over 20 years. We share an interest in those who have suffered traumatic brain injury. As a neuropsychologist, Dr Priestley has accumulated a wealth of understanding and experience of the long-term effects of head injury, encompassing the entire spectrum from the subtle to the most severe. He has a fine ability for interpreting cognitive test results in terms of their impact on the day-to-day life of the patient. I have always had confidence in his judgemental skills and opinions and I frequently recommend him to instructing solicitors especially for the more complex or challenging cases.’

‘His opinions have invariably been arrived at after meticulous consideration of all the available evidence and a thorough and fair assessment of the individual Claimant. Without trespassing into other areas of expertise, he provides a helpful and practical approach when discussing matters with experts from other disciplines when considering the day-to-day consequences of injury on a particular Claimant.  I always feel confident that Dr Priestley will be able to explain his opinions cogently, clearly and persuasively, even under the most challenging questioning in Court.’

‘Dr Priestley is one of the leading neuropsychologists practicing in the medico legal area in the UK today. His approaches to evidence gathering, reasoning and decision making exemplify good practice in this often complex arena. His work has helped to set the barr over many years for neuropsychologists wishing to help inform the Court on neuropsychological matters. His professionalism means that he is a highly sought after expert, clinician and professional mentor. Only a select group of other practitioners could claim similar experience and expertise. His reports are of the highest standard, robustly supported by rigorous evidence collection and sound reasoning.’

‘I consider Dr Priestley to be an extremely able and knowledgeable Neuropsychologist.  His reports are meticulously prepared.  He is always clear in terms of his recommendations and the reasons for these, always giving consideration to the appropriate legal principles involved.  Dr Priestley maintains very good relationships with those instructing him and the other relevant experts both within his field and other specialisms associated with brain injury. He is always focused on the relevant issues, and produces his reports within the appropriate timescale.

With experts instructed for the opposite side, Dr Priestley’s approach is always well-reasoned.  He has a very clear view even where there may be fundamental differences between experts of the same specialism. Dr Priestley’s understanding of current PI law and procedure is comprehensive which assists me as a lawyer when instructing him, and his overriding duty to the Court is unquestionable.

He is simply a leader within his field.  His  insight and consideration of clients who have been through and survived such life-altering injuries is a huge credit to himself and his profession.’
