My 8-year-old son, Arjun, had been complaining of stomach aches for weeks. Our local doctor just said it was gas. I was so worried. We got an appointment with Dr. Rajiv Singh, and honestly, the waiting area was packed. But when we finally saw him, he spent a long time just talking to Arjun, getting him to relax. He didn't just look at the reports; he examined him so gently. He figured out it was a mild food intolerance, not anything scary. He explained everything to me in simple terms and even drew a little diagram for Arjun on what foods to avoid. I felt heard for the first time. He saw my child, not just a patient.

Had a persistent fever and fatigue for 10 days. Went to Apollo Lucknow. Saw Dr. Rajiv Ranjan Singh. He ordered the right tests, no unnecessary ones. Diagnosis was a specific viral infection. Prescribed clear medication and rest. Followed up in 3 days. Fever broke. Felt better. Efficient. No fuss. Good doctor.

I was quite nervous about my check-up, as I’d been putting it off. Dr. Singh has a very calm way about him. He listened quietly to all my little worries, even the silly ones about the blood work. He never made me feel rushed. His advice was practical—small changes to my diet and a short walk each day, rather than anything drastic. It felt like guidance from a knowledgeable friend. The hospital is large and can feel impersonal, but in his room, it was different. I left feeling reassured.

Wow, what a difference! I’d been dragging myself to work with zero energy, thinking it was just stress. Dr. Rajiv Singh actually dug into it. Turns out my vitamin levels were completely off! Started the supplements he suggested, and within two weeks, I felt like a new person. My family noticed the change immediately. He’s sharp, caught what others missed. The clinic was running late that day, but it was worth the wait. So glad I went to see him!
