Professional background

Professional background

I am a Legal Director in the medical negligence team at Fieldfisher. I have practiced in this area since qualifying in 2010.

I have extensive experience of representing catastrophically injured claimants and their families, helping them to rebuild their lives through rehabilitation and substantial damages settlements. I have also represented many families following fatal accidents and the loss of a loved one as a result of substandard medical treatment.

I have dealt with a wide range of case types including delayed diagnosis of cancer, fatal accidents, acquired brain injury, amputation, spinal injury, birth injury, and cosmetic surgery. My experience in neurological injury, delay in diagnosing cancer cases and fatal cases is particularly extensive. For example, I have worked on many cases involving spinal injury caused by Cauda Equina Syndrome and substandard surgery. I have also represented many claimants who have sustained a brain injury as a consequence of substandard stroke treatment and falls in hospital as well as claimants who have suffered as a consequence of a delayed diagnosis of cancer including ovarian, oesophageal bowel and rectal cancer.

I develop strong working relationship with my clients and understand the life changing physical and financial circumstances they find themselves in. I work hard to provide them with direct, clear advice and closely support them through the litigation process.

Having contacted Fieldfisher to help deal with a personal injury case I was appointed Marcos Eleftheriou to carry out an investigation and deal with what was to me a very personal, serious matter. Having dealt with various different solicitors over the past few years with other family matters I can honestly say Marcos is the first person I honestly felt and believe had my best interests at heart, from start to finish I took his advice knowing that what he said or did was going to be the best option for myself, he listened, gave me good advice, and took a lot of stress out of my hands in what I can only describe as a very professional but caring manner. Now my case is finally at an end with a good outcome I can move on, I will always be grateful for the support and help he gave me. Forever grateful.

Client
Marcos, I can’t thank you enough for everything you’ve done for us and more so the way you have handled this case with such sympathy; you’ve been incredibly delicate throughout which has helped me massively. It’s been a tough road but I’m so relieved it’s over now. I couldn’t recommend you enough Marcos.
Client
From the very beginning Marcos was professional, informative and supportive. I felt very well supported throughout the 5 years of my case with frequent updates and a lot of support for my difficulties. I could not be happier and more impressed with the professionalism in handling my case. Marcos was so informative at every stage of the process. I never doubted him in fighting for my legal rights. I could not have more respect for Marcos as a professional in his job.
Client
Marcos is a great communicator. There has not been a single occasion where he has not responded to my emails or calls. He is highly professional, displays expert knowledge and gives me good legal advice to assist me in making decisions. He has a very caring and understanding manner and listens to my concerns. I could not be in better hands.
