Dr is a very friendly and human person, explained the problem and next steps of action to be taken very clearly. Dr performed surgery on my father on 13th August 2021.under local anesthesia. Post-surgery Dr was very caring and enquired about my father’s health over the phone. Thank you very much, Dr for the excellent treatment and personal attention.


    • Major Dr.Rengan, Notably he is very positive in his approach and honest in views and encouraging with words that make patients at ease. Would recommend Dr.Rengan for any complex issues in gastroenterology, laparoscopy, and abdominal problems, he also takes time and pain to explain the problems and options (patience and a humane approach is a rare commodity these days). It’s not out of place to mention, he is a very patriotic and devotional doctor which is one attraction to me.

    • Amazing doctor. He is thoroughly experienced in his domain. I took my mom for hernia and gall bladder surgery; she is obese and we were a bit scared on to proceed. The doctor really comforted us explaining the surgery in detail and also quoting examples of his past experience. He is really calm and has the knack of rightly dealing with his patients. It’s been 2 weeks since the surgery is complete and my mother is recovering and able to walk now. Thanks a lot, Dr. Rengan. You are awesome. I highly recommend Dr. Rengan as he is the best in his domain.
