My father suffered a major stroke at 3 AM. Dr. Tiwari's team performed mechanical thrombectomy within hours. Today, my father walks and speaks normally. We owe his life to this team.
I suffered from severe back pain and sciatica for years. Dr. Tiwari performed endoscopic spine surgery — just 8mm cut! I was walking the same day and back to work in 10 days. Miraculous.
Brain tumor surgery — words that filled me with fear. Dr. Tiwari explained everything clearly, operated with neuronavigation guidance, and the tumor was completely removed. Outstanding surgeon.
I was told I needed open spine surgery abroad. Dr. Tiwari performed endoscopic PELD under local anaesthesia. No big surgery, no general anaesthesia, home the same evening. Life-changing.
Trigeminal neuralgia — the worst pain of my life. After failed medications, Dr. Tiwari performed MVD surgery and I woke up pain-free. I can finally eat and smile without agony.
My brain aneurysm was found incidentally. Dr. Tiwari discussed coiling vs. clipping in detail, performed coiling, and I never had the rupture that could have killed me. Eternally grateful.
