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.

Due to my medical condition I have been a patient at Froedert for the past 20 years. This was my first appt with Dr Zwagerman. I have met many doctors over the years and am so confident and comfortable with the care I am receiving from Dr Zwagerman. He and his entire staff were above and beyond my expectations.

Dr. zwagerman saved my life. I had no idea I had a brain tumor. I fell, had a Ct scan at a different hospital and was immediately sent to Froedtert. Dr. Zwagerman performed a very delicate and difficult surgery where the golf ball sized tumor was hard as a rock. My MRI yesterday showed no tumor and my brain completely filled in. Thank God for Dr. Zwagerman. His whole team is amazing. A thousand thank yous to all of you.
