Care Philosophy

This content was provided by Dr. Souweidane "I have dedicated my career to the surgical treatment of children with brain and spinal disorders. I'm a father myself, so I pride myself on treating each patient with the compassion I would want for my own children. I like to say that a child who becomes my patient is my patient for life - the best gifts I've ever received have been the wedding announcements of my former patients!"
