Our 5-year-old, Arjun, had been running a high fever for days and was just so listless. We were really scared. Dr. Vaidhyanathan at Apollo Firstmed saw us, and the way he spoke to Arjun first, getting him to smile a little, put us at ease. He explained everything to us in simple terms—what it likely was, what to watch for. He didn't just treat the fever; he treated our worry. The follow-up call from his team the next day to check on Arjun meant a lot. He's back to his noisy, energetic self now.

Had a persistent stomach issue for weeks. Went to see Dr. D Vaidhyanathan at Apollo Firstmed. Clinic was busy, had to wait a bit. He listened, asked clear questions, ordered the right tests. Diagnosis was straightforward, treatment worked. No fuss, effective. Would see him again if needed.

I was quite anxious about my ongoing fatigue. Dr. Vaidhyanathan has such a calm manner. He didn't rush me at all, even though I know the waiting room was full. He listened to everything I said, and his advice felt very considered and kind. The hospital itself is large, but his clinic felt like a quiet space. I left feeling heard and with a clear path forward, which is what I needed most.

What a relief! I'd been to two other doctors for this nagging cough and nothing helped. Found Dr. Vaidhyanathan. Finally, someone who looked at the whole picture, not just the symptom. He figured it out in one visit. Started the new medication he suggested, and within three days I felt like a new person. So glad I went to Apollo Firstmed and got to see him. He really knows his stuff!
