“Mayo Clinic in Arizona is a unique combination of a world-class medical institution with a mid-size hospital and staff. Training here, I had access to the highest expertise and boundless resources, and I came to know most of the neurology department and many hospital and clinic staff by name. I felt like I had every opportunity to succeed without getting lost in the crowd.”

“The field of medicine was suggested by a college professor who thought it would fit well with my endless quest of ‘how and why?,’ but ultimately I chose the profession for the opportunity to help people continue doing what they love in spite of illness. Neurology is intellectually challenging with a wide range of diagnostic mysteries. It provides the unique opportunity to care for patients who feel (and are vulnerable), as disorders of the nervous system affect our core being and how we interact with the rest of the world.”

"As a visiting student, I did a rotation at the Department of Neurology's headache division at Mayo Clinic in Arizona. That invaluable opportunity made me realize how tormenting headaches can be, and how adequate treatment can tremendously improve the quality of patients' lives. Most importantly, I was very impressed with how the consultants were devoted to the residents' education. I was convinced that Mayo Clinic in Arizona would be the perfect place for me to launch my career in neurology."
