Message from Dr Adrian Saurajen

"I have been very blessed and humbled to have been given the opportunity to study medicine and in particular ENT, pediatric ENT and Sleep Surgery. I believe that the practice of Medicine is a calling, a great honour and a very precious gift from God. So many people have either mentored me or been so generous and kind with their time in taking me under their wings and teaching me what was often not found in textbooks but what they learnt from experience. In treating patients, I have truly learnt that the practice of medicine is one of humility, of serving and that with time and experience; medicine moves from just being a science to also truly becoming an art. I thank God for having led me on this road; which at times has been challenging but ah.....always so fulfilling!  I also want to thank the many patients who have taught me that we are not merely treating diseases but that we are treating people..."
