Neurosciences – Froedtert Hospital Clinic

I believe that treating patients is more than simply treating the problem they present with. Patients often come to my clinic with a new diagnosis and with complex histories that make each patient unique. The best way to treat each patient is to discover what is important in their lives, educate about the presenting problem, and formulate a treatment strategy that takes all of these things together to arrive at a treatment plan. Each patient needs to be evaluated independently to arrive at a unique treatment for each patient.
