About
A career built on volume, precision, and academic rigour.
From establishing a department single-handedly at a regional cancer centre to leading a surgical oncology directorate, every step has been shaped by patient outcomes and continuous learning.
Currently, I serve as Consultant Gastrointestinal & Thoracic Oncosurgeon at Zydus Hospital, Ahmedabad — a high-volume centre where I focus exclusively on cancers of the oesophagus, stomach, colon, pancreas, and lung, with strong emphasis on robotic and minimally invasive approaches.
My MCh in Surgical Oncology was completed at Gujarat Cancer & Research Institute, Ahmedabad — one of the largest cancer centres globally — after securing the 1st position in the All India MCh Entrance Examination. The training there shaped much of my expertise in head & neck oncology and microvascular reconstruction.
Earlier in my career I had the privilege of establishing the Department of Surgical Oncology at the Regional Cancer Centre, Raipur, as the sole surgical oncologist — managing a centre that served around 30,000 cancer patients annually with roughly 50 major cancer surgeries each month.
My approach is multidisciplinary, evidence-driven, and patient-first. I work closely with medical oncologists, radiation oncologists, pathologists, and reconstructive surgeons to ensure every patient receives a treatment plan tailored to their disease and life context.
The surgical videos shared on this site are educational in intent, drawn from my work and the work of my mentor Dr. Mahesh D. Patel at Zydus Cancer Hospital, Ahmedabad — where I am part of the GI, Thoracic, and Robotic Surgery team.
