Doctor: Dr. Naresh Trehan K Hospital: MGM Hospital Chennai

Needed to get a cyst removed. Honestly, I was nervous at first, but Dr. Swamikannu made it simple. The whole thing at MGM was over in what felt like an hour. He talked me through each step as he did it, which kept me calm. The stitches were so neat you can barely see them now. It was just a straightforward, no-fuss experience, exactly what you hope for.

Doctor: Dr. Naresh Trehan K Hospital: MGM Hospital Chennai

The parking at the hospital was completely full that day, which put me in a bad mood before my appointment. But the front desk staff helped sort it out, and the nurse who took my vitals was really kind. The waiting area was clean and quiet, which helped me settle down. By the time I saw Dr. Swamikannu, I was a lot less frazzled. It's the little things that make a difference.

Doctor: Dr. Naresh Trehan K Hospital: MGM Hospital Chennai

What stuck with me was how Dr. Swamikannu talks to you. He doesn't rush. When I was worried about some test results, he sat down, looked me in the eye, and broke down what all the numbers meant in plain Tamil. He has this calm way about him that makes you feel you're in good hands, not just another file on his desk.

Doctor: Dr. Naresh Trehan K Hospital: MGM Hospital Chennai

I've been seeing Dr. Sivaraj for over a decade now, ever since my diabetes diagnosis. He doesn't jump on every new trend, and that's what I like. He knows my history, remembers my family, and his advice is always steady and practical. The clinic at MGM can get crowded, but he never rushes our appointments. I trust him completely.

Doctor: Dr. Naresh Trehan K Hospital: MGM Hospital Chennai

I'd been to a couple of doctors for this nagging abdominal pain, and everyone just said it was stress. Dr. Swamikannu actually listened. He asked questions about things no one else had, ordered a specific scan, and found the issue—a tricky adhesion from an old surgery I'd almost forgotten about. He explained it with a diagram on his notepad, which really helped. Finally felt like someone connected the dots.
