About
A surgeon focused on the person, not just the procedure
“The field of neurosurgery is not about the procedures but rather the long-term relationships I build with my patients.” Dr. Arnaout often meets with patients several times before discussing surgery, and stays closely involved throughout recovery — for surgical and non-surgical patients alike.
“The brain is the last and grandest biological frontier, the most complex thing we have yet discovered in our universe.”— James Watson
