Mayo once said, “There are two objects of medical education: To heal the sick, and to advance the science. Dean, Mayo Medical School Student Success • Eighty-six percent of Mayo fourth-year students report matching with one of their top three residency choices. Mayo Medical School uses a patient-centered focus along with the expertise, compassion, and traditions of Mayo Clinic to educate and prepare medical students to be physician leaders in 21st century medicine. Mayo Medical School Quick Facts Each year, Mayo Medical School enrolls a select class of 50 medical students. Our students are a diverse group of high-achieving men and women who possess superior academic credentials, leadership characteristics, and a sincere dedication to service. Mission - Mayo Medical School will use the patient-centered focus and strengths of Mayo Clinic to educate aspiring physicians to serve society by assuming leadership roles in medical practice, education, and research. William Worrell Mayo to Minnesota in 1855, medical practice in the United States underwent a radical transformation. When his two sons, Will and Charlie, joined the practice in the 1880s, Mayo Clinic, the first and largest integrated medical practice, was born. Will and Charlie Mayo helped found and develop the medical school at the University of Minnesota. Mayo Medical School has trained and graduated more than 1,400 students since 1972. Curriculum By deeply and broadly exposing our students to the many faces of human disease and health, the Mayo Medical School curriculum is designed to greatly improve students’ preparation for the complex challenges of 21st century medicine. They key to the innovative Mayo Medical School curriculum is the integration of labs and lectures with active, experiential learning in the Clinic with some of the many patients who come to Mayo Clinic annually. This tight linkage assures our curriculum is both relevant and evolving to accommodate patient needs, new disease tends, and scientific discoveries. D student Our Faculty Mayo Medical School faculty members are not only passionate about teaching, they are committed to helping every student transform information into enduring insight and understanding. This is accomplished through a variety of teaching methods suited to numerous learning styles. Also, active and cooperative teaching exercises, supported by a pass/fail evaluation system, fosters a learning system among students that encourages collaboration while eliminating competition for grades. Class of 2012 “The curriculum was very progressive and innovative and set up so classmates support each other. So say you had a block in hematology, then you would be in a hematology clinic that week, shadowing doctors and learning first hand. Class of 2010 Selectives Selectives enrich the Mayo Medical School curriculum by encouraging innovation and leadership while offering a tremendous variety of learning experiences. Selectives are a significant component of the Mayo Medical School curriculum because they - • allow students to develop important skills in professional interaction and management. Activities are not restricted to Mayo Clinic in Rochester and may be embarked upon at Mayo Clinic in Florida, Mayo Clinic in Arizona, Mayo Clinic Health System, or other national and international medical centers. Selective blocks may be self proposed or selected off a list of available clinical experiences organized through Mayo Medical School. At the conclusion of each Selective, feedback is expected from both the student and the mentor involved. Although Kayla has been extremely blessed, she was intrigued by her encounters with medicine as a child while her brother was being treated for lupus at many institutions, including Mayo Clinic in Florida. Between my father being a physician and the long illness with my brother, I had a lot of exposure to medicine and became fascinated by it. Our various conditions took us to Mayo Clinic for treatment at times, and the outcomes were always successful. The Mayo Medical School curriculum was a standout from all other schools I considered, especially with their Selective offerings. Also, I chose Mayo Medical School because of my familiarity and strong belief in the Mayo philosophy that the patient always comes first. Maybe it was the extra effort of her fifth grade teacher to make sure she caught up in her school work after years of subpar education. Maybe it was her high school teacher’s inspiring words “Mira, you have good ideas, you think very logically, you need to be more confident because you are talented. But it wasn’t until I witnessed a wedding speech in which the father of the groom asked a neurosurgeon in attendance to stand up and accept the praise and gratitude of everyone present for saving his son’s life a few years earlier that my decision was confirmed. I was overwhelmed by the emotion in that wedding hall and knew at that time I wanted to be a physician because then I could really help people experience life-changing moments. The curriculum was very progressive, innovative and set up so classmates support each other. Also, with Mayo’s dedication to public health and commitment to underserved communities, I was thrilled that a medical school shared the same ideals that I had. He enjoyed his busy life in the countryside where he learned all about hard work and discipline, but it was the respect and awe he felt for their family’s rural physician that stoked his passion to learn more and to try something different.
