Dr. Dattatray Mazumdar

Dr. Dattatray Mazumdar is one of Mumbai's most experienced neurosurgeons, with over two decades dedicated to complex brain surgery, neuro-oncology, and epilepsy care. He is best known for championing the routine use of Intraoperative Electrocorticography during epilepsy surgery — a precision technique that helps surgeons map brain activity in real time and improve outcomes for patients who haven't responded to medication. Between 2001 and 2019, he performed over 600 epilepsy surgeries as part of the first comprehensive epilepsy surgery program in Western India, with a strong commitment to making this care accessible to underprivileged patients.

Dr. Mazumdar's academic credentials are extensive — MBBS, MS, FCPS, MCh in Neurosurgery, DNB, MNAMS, and fellowships from both the International College of Surgeons and the American College of Surgeons (FACS). His career has been shaped by a spirit of collaboration as much as clinical excellence. In 1999, he was a founding member of the Joint Neuro-oncology Tumor Board between KEM Hospital and Tata Memorial Hospital — a landmark initiative that brought together neurosurgeons, oncologists, and other specialists under one roof to plan care for brain and spine tumor patients. He is also a founder member of the Indian Society of Neuro-oncology (ISNO).

Patients and families often appreciate Dr. Mazumdar's ability to explain complex neurological conditions in straightforward terms, and his calm, methodical approach in high-stakes situations. He currently practices at Gleneagles Hospital, Parel, Mumbai, and remains actively involved in academic medicine — having published over 170 research papers and contributed around 20 chapters to neurosurgery textbooks. He serves on the editorial boards of reputed medical journals and holds memberships in several leading national and international neurosurgical societies.

For international patients travelling to Mumbai for brain tumor surgery, epilepsy care, or skull base procedures, Dr. Mazumdar offers the reassurance of deep subspecialty experience, strong institutional affiliations, and a proven research-backed approach to treatment. GAF Healthcare works closely with his team to help overseas patients navigate consultations, hospital admission, and follow-up care smoothly from start to finish.
