My dad was admitted under Dr. Mahadevan. We were really scared, but he took the time to explain everything to us in simple terms, not just once but every day. He was always available on the phone for our questions, even late. It made a huge difference for our family to feel included and not left in the dark.

First time seeing a doctor alone and I was a complete wreck. My stomach had been off for weeks. Dr. Mahadevan just had this calm way about him. He listened to all my weird worries without making me feel silly, and actually laughed with me about some of them. Walked out with a clear plan and finally felt like I could stop googling my symptoms at 2 AM.

Had a stubborn skin thing. Saw Dr. Mahadevan at Gleneagles. He figured it out fast, prescription worked. No fuss, got the job done. Would go back.

I'd been putting off a check-up for years, just feeling run down. The clinic was busy, I waited about 20 minutes past my slot scrolling on my phone. When I got in, Dr. Mahadevan didn't rush. He asked about my work stress, my sleep, things I didn't even think were connected. He ordered a few basic tests I was overdue for, and when the results came back showing a vitamin deficiency, he called me himself to explain it. It wasn't anything dramatic, but that thoroughness—actually looking for the *why* behind the tiredness—is what I appreciated. I'm on a simple supplement now and feel like myself again.
