Marcelo Masri



I am a solicitor specialising in medical negligence, based in our Sheffield office. I am bilingual in English and Spanish and I am also registered as a practising solicitor in Spain, England and Wales.

On a day-to-day basis, I represent clients who have suffered an injury as a result of negligent medical treatment. I have a varied caseload, including delays in diagnosis and treatment, surgical negligence, failed orthopaedic treatment and fatal cases.

I also assist Julianne Moore on particularly complex and high value cases.

Client Testimonial

“I would like to reiterate my positive experiences when dealing with yourself and Irwin Mitchell. I consider your firm to have the highest standards of integrity and honesty.

“You definitely go the extra mile and I think the service you gave was exceptional.” – Vivian, Hinckley

What Inspired You To Get Into Law?

I studied Law with Hispanic Law at University College London, before going on to complete the Legal Practice Course at the University of Law. 

One of my favourite subjects at university was Medical Law and Ethics. I was attracted by the interplay of medicine and law and the difficult ethical questions that can arise from the practice of medicine.

What Is The Most Rewarding Aspect Of Your Role?

Health care often impacts on aspects which are intimate and central to a person's life. This is why I strongly believe in patient autonomy.

I enjoy finding answers for my clients and helping them understand the treatment that they have received. In cases where there has been clear substandard medical practice, I am rewarded when I see that justice is ultimately achieved and any inbalances are corrected meaning that individuals can move on with their life even after injury.

What Do You Like About Working At Irwin Mitchell?

I enjoy working in a great team of knowledgeable, innovative and experienced lawyers.

What Do You Do Away From The Office?

I enjoy travelling (particularly if there is skiing involved), languages and discovering new cultures and places.
