Meet Our Residents

The Adult Neurology Residency at the Medical College of Wisconsin is fully accredited by the ACGME as a categorical program. We take either six or seven residents per year (alternating years); 2022-2023 we will be welcoming six new residents. Our outstanding residents are the core of the program. To give you a better feel for our program, we have put together several videos to let you hear from some of our residents in their own words. Our Chief Residents, Dr. Jennifer Collins and Dr. Michael Dryden, have provided welcome letters as well to help you get to know them and our program better.

During our virtual interview process, you will have additional opportunities to speak with our residents (via telephone, video conference, or email). In the meantime, I invite you to view these videos to get to know us better.
