Words from current residents
See what a few of our current residents have to say about why they chose to train in the Adult Neurology Residency at Mayo Clinic in Rochester, Minnesota.
As a Neurology resident at Mayo Clinic, I am privileged to train in an environment where the needs of the patient are always the highest priority. The commitment to patient-centered care is woven into every aspect of our work, from daily clinical practice to groundbreaking research. Mayo Clinic offers unparalleled educational opportunities, guided by a faculty that is both deeply knowledgeable and genuinely invested in our growth. The collaborative and collegial atmosphere among residents and faculty creates a supportive environment where learning thrives, and ideas flourish. I am honored to be part of such a distinguished Neurology department, and I am committed to using the exceptional training I receive to make a meaningful difference in the lives of our patients.

As a resident, I feel fortunate to learn from and work with a diverse patient population presenting with both common and rare neurologic disease. This occurs alongside collaborative faculty members who are not only dedicated educators and world-class leaders in the field, but also prioritize supporting the unique interests of each resident. The camaraderie with other residency programs creates an inclusive environment where residents can thrive and pursue their passions. Above all, Mayo Clinic's primary value of putting the needs of the patient first permeates through every aspect of clinical practice, research, and education. Experiencing this culture every day reaffirms that there is no other place I would want to complete my training.

Every day I go to work, I walk in with a smile on my face. The camaraderie between co-residents and faculty makes even the hardest of days enjoyable. Residency is hard, but to be able to form friendships through this contributes to a level of resiliency that I did not appreciate until I was already here. The breadth of pathology brings a sense of joy to my nerd heart. From learning to manage bread and butter neurology to the rare diagnoses, our faculty help us learn from every patient regardless of the complexity. We are lucky to have world-renowned faculty who are experts in the field and are simultaneously approachable, down to earth, and represent the core value of how medicine should be practiced: the needs of the patient come first. Beyond the excellent clinical training, there are endless opportunities to develop and shape our career to what we want it to be, whether that be research, education, community engagement, patient advocacy, and beyond. Professionally and personally, the opportunity to train here has been fulfilling beyond what I could have hoped for.

Santiago Martinez-Sosa, M.B.B.S (he/him)Hometown: Buenos Aires, Argentina Why neurology? The nervous system is the most fascinating organ! I am enthralled by neurology's breadth and depth. The ability to localize deficits to specific neuroanatomical sites through examination is empowering. The lesion differentials are challenging and engaging. The yet undefined edges of the field invite meaningful, novel research that will transform patient care. Through neurology, we can understand and treat this incomparable organ whose function we depend entirely on and whose injury or degeneration causes unparalleled impairment. Why Mayo Clinic? There are many excellent medical institutions in the U.S., but you would be hard-pressed to find a more wholesome one than Mayo. I was floored by Mayo’s culture of collaboration, the friendly atmosphere, the humility of their world experts, the warm and pleasant staff, and the palpable driving force at the center of it all: a genuine desire to help patients to the best of our ability.
