Lisa’s former client 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 she 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.”

Another of Lisa’s former clients 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!”

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!”
