Experience You Can Trust
I am a general surgeon with over 40 years of clinical experience, now fully focused on medico-legal report writing. My NHS and private medical background includes serving as Lead Consultant for the Breast Unit at Homerton University Hospital and as an Honorary Senior Lecturer at Barts Cancer Institute.
Since retiring from surgical practice, I have dedicated my time to medico-legal work, delivering over 100 detailed reports each year.
Marcus Ornstein
I work closely with solicitors and agencies across the UK, offering reports for both personal injury and clinical negligence matters.
I am regularly instructed by a wide range of clients, and I pride myself on offering clear, well-structured, evidence-based reports, with rapid turnaround times when needed. My background gives me a broad and mature perspective on clinical cases, supported by years of academic research and teaching.
I Analyse Without Assumption
Every report is built from facts, not assumptions. I examine all available records carefully before reaching any conclusion, ensuring my opinions are grounded, not guessed.
I Remain Clinically Sharp
Despite retiring from surgery, I remain immersed in the academic and clinical world. I regularly attend medico-legal symposia and continue postgraduate teaching to stay current.
I Present With Clarity
Reports are structured, readable, and legally compliant — designed to be understood by solicitors, clients, and courts alike, without unnecessary jargon.
I Respect Every Instruction
Whether instructed by claimant, defendant, or jointly, I treat each case with the same objectivity, discretion, and professionalism.
Your Case. My Expertise.
