John Killen

Clinical Negligence Solicitor

John has worked in the law since 1989, starting as a junior clerk and has dealt with virtually every type of litigation (and non-litigation) over the years, presently specialising in complex clinical negligence cases.


Using only the best barristers and experts, his caseload typically involves cases valued over £100,000 but takes a special interest, regardless of value, in the more difficult and complex cases and actively encourages Defendant Trusts and their solicitors to engage in ADR, undertaking his first successful mediation 15 years ago. Former voluntary pro-bono legal adviser to Age Concern in Southport.

Client Feedback

“John’s letter of claim in your case was the best I have ever seen in a clinical negligence case and a model of clarity, despite the huge complexity”

“Many thanks for your guidance over the last few years, and your continued efforts to get answers about Mum’s condition, diagnosis and care”

“John has forgotten more than most solicitors will ever know”
