Neuroscience Center - Froedtert Hospital Specialty Clinics (414) 805-3666

I aim to provide exceptional quality care for patients with movement disorders. My goal is to develop a working partnership with patients through education and active engagement in their care. I believe in collaboration with patients' primary care providers, other consulting specialties and ancillary services. Together, I believe we can maximize quality of life in patients suffering from movement disorders.


Dr. Brennan was born and raised in Kalamazoo, MI. He completed his undergraduate and medical school at Michigan State University. During that time he developed an interest in Neurology and movement disorders in particular. He went on to complete his Neurology residency at the Medical College of Wisconsin and his fellowship training at the University of Nebraska Medical center in Omaha, NE.

*Dr. Brennan is the best neurologist I have seen I rated a "9" because of the time in between appts. He is booking 7-8 months out. That is too long in between visits.

He is always very attentive and listtens carefully. I never feel rushed and all of my questions are addressed.
June 3, 2019
Because I have a rare neurological disease, we discussed a medication which might be causing very low blood pressure while standing. I am trying to use less and possibly eliminating it. He has encouraged me to continuing to see a behavioral therapist to help me live with this disease.

Too many tests with undesirable results, need second opinion. Do not feel they work well with the V.A. thats the Veterans Administration.
