A highly qualified and experienced hernia specialist

His MD thesis from the University of Cambridge and carried out at Charing Cross Hospital focused on the role of growth factors in breast cancer. He is Senior Consultant Surgeon with an interest in breast diseases and surgical oncology at the Colchester Breast Unit in Essex and has been a member of The London Breast Clinic and The Gilmore Groin & Hernia Clinic since 1999.

Mr Marsh's expertise in sports injuries, and groin and hernia treatment

Following qualification he developed an interest in sports medicine and has advised on many sports, including equestrian events, motorcycle speedway and rugby.

This expertise has ensured his success since joining The Gilmore Groin & Hernia Clinic where he has become adept and experienced in assessing, diagnosing and treating patients, not only with Gilmore’s Groin but patients with herniae of all types.

His general surgical background  has led to an expertise in minor daycase surgery under local anaesthetic. At the One Stop Day Surgery Centre at 108 Harley Street he provides same day consultation and surgery for patients. He is on the surgical panel of The Mole Clinic providing rapid surgical access for their patients with suspicious lesions identified as requiring excision.

In 2006 he halved his workload within the NHS to dedicate more time to the Clinics at 108 Harley Street. He retains an active interest in cancer research and is an Honorary Senior Lecturer to the Department of Biomedical Sciences in the University of Essex.

The Gilmore Groin & Hernia Clinic

The Gilmore Groin & Hernia Clinic was established in 1991 by Mr Jerry Gilmore.

In 1980 Mr Gilmore recognised the syndrome of groin disruption in sportsmen and undertook the first successful repair. The technique later became known as 'Gilmore’s Groin' or Sportsman's Groin (and also the misnomer sports hernia). This pioneering work which has resulted in the successful and rapid restoration of many sporting careers, was recognised nationally by the award of Fellowship of the Institute of Sports Medicine in 1995. 

In 1999 Simon Marsh joined the clinic because of his surgical expertise and knowledge of different sports and their associated injuries. He was appointed Surgical Director of the Clinic following Jerry Gilmore’s retirement from practice in October 2010.

People visit The Gilmore Groin and Hernia Clinic, for a variety of reasons, most commonly they have been referred by a medical practitioner because either they have groin pain which has not responded to physiotherapy and treatment or a hernia has been diagnosed and a repair is required.
