      Dr. Christopher Kellner is indeed most treasured of all Doctors that I have the privileged to meet. Dr. Kellner treated my mother as if she was family. He consistently displayed a genuine concern from the day my mother arrived in Mount Sinai West and he did save my mother’s life multiple times. Besides being a competent, extraordinary knowledgeable and a superior surgeon above all he is filled with kindness and compassion. Dr. Kellner and his powerful neurological team worked endlessly to help my mother and they were with us every step on the way. He listened, respected our wishes and consistently educated us to help make the hard decisions and get through the many difficult times we faced for that we are and will always be grateful and appreciative.

      Dr Chris Kellner was a brilliant brain stormer as well as a top notch neurosurgeon. I felt confident in his care and there was never a phone call that was not returned. I've been to all of them, but he is a healer.

      I have mixed feelings about this doctor. I suffered a stroke very recently and was treated by Dr. Kellner. I never was told what was done to me or explained the treatment plan. I think he relies on his PA to much. His PA is downright rude and doesn’t explain anything. Mount Sinai hospital where he is affiliated is understaffed, inexperienced, and not very unorganized.

      On the night my mother had her stroke we rushed her to Mt Sinai West. We were told action had to be taken asap. In the waiting room we expected to worst. Thankfully Dr. Kellner performed the life saving surgery that gave our mother her life back. After the procedure he showed us via a before and after screen on his phone, the arteries, the blood flow, and where the blockage was removed. Two months later mom is alert and thriving and her motor skills are stronger by the day. Dr. Kellner, in a follow up visit, walked us through the procedure, educating us on how the brain operates, how stroke victims are affected, and how to provide the care and attention our mom would need going forward. His professionalism and compassion, along with the dedication of his team were inspiring and reassuring to all of us. Thank you Dr. Kellner

      Dr Kellner is the exact right doctor needed in an emergency situation such as I had in February of 2017. I had a hemorrhagic stroke while working in New York City. I was taken to Mount Sinai Hospital Emergency, where, my hero, Dr Kellner was called in. He performed life saving surgery and subsequently through the months ahead, shepherded me through several tricky complications. His intelligence and compassion make him the indispensable man for complex neurological problems.

      Chris Kellner is the most dedicated, brilliant neurosurgeon. He saved my husband's life. My husband suffered from a hemorrhagic stroke, he was on a ventilator for weeks. He also suffered a respiratory arrest (actually stopped breathing.) He was one sick man. Chris was completely honest and explained exactly what was going on and what we could expect. He treated our family like his own his family. I have the upmost respect for this wonderful neurosurgeon
