Mr Simon Marsh has been an integral part of 108 Harley Street since 1999. He is the Surgical Director of the Gilmore Groin and Hernia Clinic and a member of the Breast Clinic and the Skin Clinic. He also chairs the MAC and is a Non-Executive Director of 108 Medical Ltd.

Having trained at Trinity College Cambridge and the Clinical School, Addenbrooke’s Hospital, he was one of the few students to be awarded the William Harvey Studentship in consecutive years.

He qualified in 1987, receiving the London FRCS in 1992.  In 1996 he was awarded an MD on the Molecular Biology of Breast Cancer by the University of Cambridge and received the Intercollegiate Fellowship in General Surgery. In 1999 he was appointed as Consultant Surgeon in Colchester.

He is an Honorary Senior Lecturer at the University of Essex and established the MD research programme for surgeons in training to support their continuing education. Mr Marsh is a founder member of the Essex Biomedical Sciences Institute, the Royal College of Surgeons of England, the Association of Surgeons of Great Britain and Ireland, the British Association of Surgical Oncology, the Association of Breast Surgeons, the Royal Society of Medicine, the Hospital Consultants and Specialist Association and the British Association of Sports and Exercise Medicine.

He has a keen interest in medical education (not only for doctors, but also for the general public) and has lectured both nationally and internationally on aspects of breast disease and Gilmore’s Groin and produced articles and videos that are available on the internet as well as publishing papers on breast diseases, the molecular biology of breast cancer, Gilmore’s Groin, hernias and minor surgery.

The Gilmore Groin and Hernia Clinic has treated more than 9000 people for groin problems, including over 500 internationals, since it was founded in 1980. It pioneered the team approach to diagnosis and treatment of groin problems. The standard anatomical repair of Gilmore’s Groin is now termed the Marsh Modification of the Gilmore Technique, reflecting the adaptations that have been made since 2010.

His wife, Fiona Rowe, is a GP and senior partner in her practice. He has two grown up daughters, Grayling, a vet at a large country practice (“The Barn”) on the Essex/Suffolk border (large and small animals) and Freyer, who is Head of Science at The Felixstowe School in Suffolk. Thanks to Mrs Marsh(!) they also have 4 dogs, 5 cats, 4 horses, 2 donkeys and 2 pet pigs!
