Lisa's former client

I appreciate your wishes and obvious feeling of care and regret for me. I very much also appreciate the work that you have done on my case to get to this point. I know it hasn’t always been easy to access the information you needed to, but you have clearly tried very hard and got there in the end, even pursing avenues that I didn’t realise or wasn’t aware of. I am very grateful to you for the effort you have put in. I do believe you have done your utmost.

Lisa's former client

We are very grateful for the practical assistance you have given us in circumstances that were very difficult for us and for the manner in which you have handled my mother's claim which has been both professional and sympathetic. I appreciate that you will have done far more than has been immediately apparent and believe the outcome to be far better than might easily have been the case. We have indeed been fortunate to have had you acting on our behalf.

Lisa's former client

Consistent support and advice has been shown since my accident three and a half years ago, to concluding with a settlement. I am indebted to Thompsons Solicitors for the professional, calm and realistic approach from a fantastic team.

Lisa's former client

After a work related fall, I contacted my trade union, Unite, and was represented by Lisa Gunner and her friendly team at Thompsons in Bristol. Throughout the process, I was kept well informed of developments and had to meet with a number of excellent specialist clinicians who were caring and informative. I felt that, through the whole case, the support and my wellbeing was at the heart of Thompsons business ethos. The case concluded, to my satisfaction, in less than two and a half years. I cannot thank and praise Lisa enough.

Lisa's former client

The staff at Thompsons did an excellent job of bringing a complex and difficult claim to a very successful conclusion. Going to Thompsons was a life-changing decision. I’m so glad we did it.

Lisa's former client

When my son was the victim of a serious RTA in October 2021 it was the most traumatic and difficult period. I was recommended Thompsons Solicitors by a family friend and I shall be forever grateful. It has been a very long road to successfully conclude the civil claim due to a variety of reasons but thankfully from the very beginning I was able to leave everything in Lisa’s (Lisa Gunner/Bristol Office) capable hands and focus on my son and his recovery. Lisa has guided us through the whole process and is extremely knowledgeable, kind and empathetic with nothing being too much trouble, she has taken the time to explain processes in detail, in a way we understood and out of hours if necessary. Lisa is a credit to your company and we would not hesitate to recommend Thompsons to anyone that found themselves in the position of needing a Law Firm.
