Doctor: Dr. Mahesh Janarthanan Hospital: Apollo Children's Hospital Chennai

My son had a fever that just wouldn't break, and as a new mom, I was a complete mess. The hospital was busy and I was so nervous waiting. Dr. Mahesh came in and just had this calm way about him. He explained everything about viral fevers in kids in a way I could actually understand, without making me feel silly for worrying. He didn't rush us at all. I left feeling like I could actually handle this, which was a huge relief.

We've been bringing our daughter to Dr. Mahesh for a few years now. He always remembers her, which is so nice. He speaks softly and really listens to our concerns, even the small ones. Last visit, my little one was scared of the stethoscope, and he was so patient with her, letting her hold it first. It's just a very gentle experience. We're very grateful for his care.

Doctor: Dr. Mahesh Janarthanan Hospital: Apollo Children's Hospital Chennai

What a difference! My teenager had been feeling run-down for weeks, and our usual doctor was stumped. We got a referral to Dr. Mahesh. He actually sat us both down, went through everything again, and asked my son questions directly. He ordered one specific test that finally gave us an answer—it was a simple vitamin deficiency! Started supplements and my kid is back to his old self. So glad we saw him!
