Chartered legal executive Lisa is part of Thompsons Solicitors’ Medical Negligence and Personal Injury Teams. 

Based in Cardiff and covering cases across the South West and Wales, Lisa has eight years of legal experience and runs a varied high value caseload of clinical negligence matters as well as providing assistance to senior solicitors on more complex cases.

Lisa provides representation for clients who have suffered orthopaedic injuries, delayed cancer diagnoses, brain injuries, hypoxic brain injuries at birth, cerebral palsy and GP negligence. Lisa also represents a number of clients who have suffered as a result of receiving a mesh implant.

A tenacious investigator, Lisa is focused on ensuring clients who have sustained a life altering injury as a result of negligent treatment receive maximum compensation.

Kind and compassionate, Lisa is keenly aware that those who have suffered medical negligence are left to rebuild their lives after such trauma, with many requiring additional treatment or therapies which they would not usually have access to under the NHS. 

It is very rewarding for Lisa to see her clients’ lives change in a positive way during the course of a claim and being able to obtain justice for victims of clinical negligence is Lisa’s favourite aspect of working at Thompsons. 

Outside of work, Lisa volunteers at the Bridgend branch of the Headway brain injury charity, where she is also a committee member. As well as keeping active, travelling and exploring new cultures, Lisa also bakes in her spare time and enjoys rustling up treats for charity events. 


Failure to diagnose claim: Lisa secured a settlement of £140,000 for the family of man who died after medical staff failed to diagnose a malignant liver lesion. 

Cerebral palsy claim: Lisa’s client was left with cerebral palsy following a birth injury. The case is still ongoing but Lisa has secured a significant interim payment to enable the instruction of a case manager and therapies for her client. 

Surgical error claim: In an ongoing case, Lisa is acting for a claimant who had incompatible components inserted during orthopaedic surgery, a scenario classed as a “never” event by the hospital.

Mesh impact claims: Lisa is acting for a number of clients who have had mesh inserted during vaginal surgeries. These cases cover a multitude of issues including whether the treatment was appropriate, whether other treatment options were discussed and whether the claimant gave informed consent.


Lisa’s former client said: “I am so pleased that you came onboard with our claim. You are very dedicated and professional with a lovely easy to talk to manner. You are a credit to Thompsons!”

Another of Lisa’s former clients said: “I would just like to take this opportunity to say a very big thank you to Lisa Osborne who has helped me and my wife through the hardest times. From the day Lisa took over this case she contacted us on every issue and aspect. She explained everything very thoughtfully, nothing was ever a problem and she made home visits to save me and my wife travelling, even on the weekend so it would be more convenient for us.”

A third client said: "Thank you for not only the amazing result we got to, but the tremendous support you have given me. There have been many times during this process that I could have quite easily lost the plot but you kept me calm and focused.

"I will never forget what you have done for me and you fought all the way till the end!”
