I had colonoscopy done with Dr Dennis and everything went smoothly. He gave assurance all throughout and sure enough, it was completely painless and worry-free. Dr Dennis is an expert in his field and you will be in good hands, I'm sure. I'm also really grateful for the fact that he goes beyond what is expected of him by even sharing his Whatsapp number and making himself available for queries and such. My first time seeing a doctor, more so a specialist, sharing his personal WA number to patients honestly. It made a lot of difference. It was both a pleasure and honour having him as my gastro in Malaysia and would happily recommend him to anyone looking for a trusted gastro in PJ. Thank you so much Dr Dennis and please stay healthy so you can keep helping more patients 😊

Dr. Dennis did a great job with my first ever gastroscopy. He has been really professional and has shown true commitment to solve my health issues and explained everything to me in a very clear manner. All of the staff was great – they were helpful, patience and helped with my insurance. They ensured I had a smooth prep and follow-up. I am so glad I chose Dr Dennis and would highly recommend to anyone.
