Neurosciences – Froedtert Hospital Clinic

Epilepsy exacts a horrible burden on quality of life. Thankfully there continues to be a steady stream of innovative treatments (both medically and surgically) to fight this disease. My role as an epilepsy surgeon is: a) to provide patients with safe access to the complete armamentarium of available surgical procedures; and b) to communicate an honest assessment about the risks and benefits of the available options. I see myself as a partner with both the patient and their epileptologist in reducing (ideally eliminating) the burden of this awful disease.
