We met with Dr. Rupasinghe in person in June and had a follow-up consultation in August. Throughout both appointments, he provided excellent advice and recommended targeted tests, which have significantly improved my son's situation.
What a wonderful doctor - would highly recommend. Very open and transparent and easy to talk too.
10/10 experience seeing Dr Kush. He took loads of time to go through everything with us and I left the appointment feeling so much better and clear on next steps. He was really lovely with our baby too. Would 100% recommend!!
He’s the best doctor I ever had he really made me feel comfortable with ulsrritve colitis and coliac disease and was really helpful
Dr Kush is great with kids and parents alike, kind, friendly, extremely professional and patient. Highly recommend.
Dr Rupasinghe developed a really good rapport with my son and was very approachable, putting him at his ease talking about his medical condition. He was also clear with his explanations and gave us the time to ask questions. Thank you very much for your help and support.
Dr Rupasinghe was so friendly and professional. Answering any questions asked and giving a clear plan what will happen next . He is so understanding , a lovely Dr .
Dr Kush has a wonderful approach with my daughter—and with her anxious mum, too. He has a great ability to communicate the key aspects of her diagnosis and its treatment in a way that is both clear and reassuring, while tailoring his manner to what works best for my daughter. His professionalism, empathy, and ability to build trust gives us great confidence in the care he gives my daughter.
Dr Kush was so good with my daughter, she’s only 8 and he made sure that he spoke with her not just with me which was so important to make her feel part of the process. His swift work and diagnosis will have life long impact.

Thank you! I so pleased that she trusts in me, and of course she is the most important person involved! I will always have her front and centre of everything we do. So pleased I was able to help her so much.
Our visit was very professional. Not rushed and great care taken. Test were done and results were shared very quickly. Highly recommend. My daughter has autism, anxiety and adhd and felt as ease and comfortable in her appointment.

Thank you so much for the kind words. So so pleased we built a great rapport together and I'm so glad she trusts me so much. Thrilled I was able to help her.
Dr Rupasinghe is a very skilled, knowledgable and caring doctor who I would trust with my own child. Always a pleasure to work with!
