At Hartford HealthCare's Ayer Neuroscience Institute, we’ve taken the concept of a second opinion to a new level.

Each week, all our specialists—neurologists, neurosurgeons, neuropsychologists, neurointensivists, and neuro-critical care nurses—meet to review each individual case. Together, they pool their knowledge and experience to give you the most advanced treatment plan possible.
