“Science. Skill. Safety
For Every Child”
My Practice
I specialise in operating on children, right from the time they are born up to their late teens. Paediatric surgery needs care, commitment and a genuine love for what you do and that’s what I bring to every child I treat. I’m based in Chennai, India, and we care for children from all over India and from abroad, offering safe and reliable surgical care for every family that walks through our doors. I work as a team with senior pediatric surgeona and urologist Dr P Balamourougane at Dr Mehta’s Hospitals and Apollo Children’s Hospital in Chennai
