Gabriel Gabriel

Gabriel is Head of the Guildhall's Personal Injury team. He has a longstanding specialist practice in personal injury and clinical negligence including catastrophic cases. He has broad experience of liability issues spanning fatal accidents, industrial injury, RTA/MIB claims, occupier/public liability claims, disease cases, cases of post accident clinical negligence or involving technical factual issues.

Gabriel has regular involvement in quantum disputes involving fatality, paralysis, traumatic brain injury, spinal injury, amputation and claims involving CRPS / Somatoform / or other chronic pain disorders. He enjoys a busy practice, is instructed by claimants and insurers and is described in Legal 500 as "highly effective" and "ultimately the advocate you want on your side" and is ranked at as a tier 1 junior.

He is ranked in Chambers UK as "Extremely thorough in his preparation, and knowledgeable of the relevant law" and "Always on top of the detail." Recent cases include a T12 paraplegic, a novel issue relating to contributory negligence in a lung cancer claim (destined for the Court of Appeal in 2017), a bilateral above-knee amputation and paralysing discitis caused by a workplace laceration with subsequent clinical negligence.

Alongside these less higher-end claims Gabriel's practice also includes cases spanning down to lower values - a consequence of loyal relationships forged over time. Solicitors particularly value his approachability, commercial awareness, and ability quickly to gain the confidence of the lay client, especially in cases where problems have arisen or where careful handing is required.
