- I was worried about seeing a consultant for my problems as they were personal and not nice to talk about. But he put me at ease straight away with his positive manner. He took time to carefully listen to my issues. Treatment was performed sensitively with good care.
- Very professional and cheery manner, explains things clearly in layman terms. He quickly establishes empathy to put at you at ease. I asked for him for specifically for my treatment following positive experience by my wife Marina Hosgood for recent treatment by him.
- Warm, knowledgable, reassuring - interested in preventative care too
- I selected Dr Arun based on reviews I had seen online, and he entirely lived up to my expectations. He was clear with me at our first outpatient what treatment was necessary and added on a colonoscopy to rule out any serious conditions. The procedure was conducted perfectly.
- I highly recommend Mr. Shanmuganandan services as he is world class healthcare provider taking in consideration even the smallest or concerns raised. With an impeccable attention to details he addressed all of my current but also future concerns which made me feel reassured.
- I received the best care and advice and would recommend to anyone
- I went to Mr Arun for a second opinion and although I have to wait for the result of tests before Mr Arun is able to give me a diagnosis, he is a very kind and compassionate Consultant. I wished he’d been my Consultant from day one.
- Dr Shanmuganandan is a consummate professional. He explained things to me clearly, treated me with the utmost respect and care and made what could have been a stressful experience almost pleasant. Highly recommended.
- I am very happy with the care I received from Dr. Arun. He is very knowledgeable and friendly and seemed genuinely interested in my case and family history, which is not very common these days. He made me feel at ease during a delicate procedure. I am grateful I have found him!
