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.

Always gracious and professional. Thank you!!
He was hands down the most genuine doctor I've ever met.
The MA was fantastic; she was enthusiastic, listened to me and very helpful. Gave me some water. Dr Zwagerman was so helpful put a STAT order in for my MRI and I got squeezed in early Monday. Great teamwork! Thank you
We appreciate Dr. Zwagerman's caring attitude & Sense of humor!
Dr Zwagerman is a outstanding dr he explains everything so that when you leave you feel more comfortable and confident.I would recommend him to anyone
I have not had a bad experience at all with staff or doctors. The care I received was excellent.
Dr Zwagerman is fantastic. I am positive he had a line of patients waiting in exam rooms but made me feel like he had all day to talk with me. He answered all of my questions and explained things clearly. Despite the probability that I will have to have surgery he made me feel so very confident in the process and at ease with how he will care for me. We are so very blessed to have him as my neurosurgeon
