Dr Ronnie Mathew

Dr. Ronnie Mathew is a Senior Consultant Surgeon with around 27 years of Surgical experience. He has dual Specialist Registration in General Surgery: from both United Kingdom (General Medical Council) and Singapore (Singapore Medical Council). Dr. Ronnie’s Sub-Speciality interest is in Colorectal Surgery. He is a keen proponent of Minimally Invasive Surgery, especially Robotic Surgery. Ronnie was amongst the first group of six colorectal surgeons in Europe to be formally accredited to undertake Robotic Colorectal Surgery by the European Association of Robotic Colorectal Surgery.

He undertook all his Surgical training in United Kingdom, including extensive training over 11 years. The last seven years of this was in a comprehensive Higher Surgical Specialist training in General Surgery and its various Sub-Specialities. He also spent additional three years primarily for clinical research in surgery.

Following his completion of training and attainment of Specialist Registration in UK in 2011, he undertook various International Fellowships over 2012-2013 (including in Singapore [SGH], South Korea, and Switzerland). In 2013, he then returned to take up a Consultant position in one of UK’s busiest Tertiary Hospitals (it usually comes within the top three in UK for Colorectal Cancer workload [as per NBOCA data] as well high Emergency General Surgery volume). Here he was instrumental, as a co-lead, in setting up the Robotic Surgery programme. He was also part of sub- specialist group in the regional county area for treating Pelvic Floor Disorders (for Leicestershire) and Trans-Anal Minimally Invasive Surgery for early rectal cancer (East Midlands).

Following an invitation from the Department of Colorectal Surgery at SGH, Dr. Ronnie came back to Singapore in March 2016 to join the Department as a Consultant. He became a Senior Consultant few years later. He held the post of Director of Research at Colorectal Surgery Department along with various SGH board memberships including in Robotic Surgery. After spending eight years at the Dept. of Colorectal Surgery at SGH, Ronnie left to start his private practice in April 2024.

In addition to his decades of clinical experience and specialist expertise, Ronnie has won multiple international awards/recognitions including ‘International Trainer of the Year’ (awarded by Association of Coloproctology Great Britain and Ireland. Till to-date, Ronnie is the sole recipient of this award outside of UK). He also won the prestigious ‘British Travelling Fellow to USA’ award in 2015 (awarded to only one person each year). As part of this award, he chose to undertake Travelling Fellowships to Cleveland Clinic Hospital and University of California Irvine Hospital. Nationally, he has won multiple awards, including the award ‘Top 10 most Impactful Healthcare projects’ at the Singapore National Healthcare IT summit in 2018. This was for the project led by Dr. Ronnie: ‘Artificial Intelligence in Colorectal Cancer: Prediction for Recurrence, Optimal Surveillance, and Treatment’. He has over forty publications including in Nature, Lancet, Annals of Surgery etc.
