  • I consulted Dr. (Major) RS Rengan in 2022 for gallbladder stone surgery, which was successfully performed. In 2023, after a cesarean delivery, I faced a non-healing wound for two months. Despite my gynecologist’s assurances, the issue persisted. When I consulted Dr. Rengan, he immediately diagnosed it as NTM (Non-Tuberculosis Mycobacterial Infection), later confirmed through biopsy. Under his care, with antibiotics and injections, my wound healed completely. Dr. Rengan’s expertise, kindness, and positivity make him extraordinary. His care goes beyond medicine, inspiring confidence and hope. My family and I are deeply grateful for his support during our toughest times. Truly, he is a blessing to his patients and a remarkable doctor. Thank you, Dr. Rengan!

  • I visited Dr. Rengan for fixing my inguinal hernia condition. Doctor is top notch and takes superb care of the patient. He gave lots of post operative care and good follow up from both himself and his assistant is very good. Doctor Rengan shows pictures from the surgery too. Details of all the information related to the care are very well discussed. The amount of time spent to make the patient comfortable, and recommended post operative medicines to ensure best recovery, makes the entire experience a seamless journey. Thanks a lot to the doctor and his team.
