Sports Medicine Fellowship

About the Fellowship

Twin Cities Orthopedics offers a one-year ACGME accredited Orthopaedic Sports Medicine Fellowship beginning August 1st and concluding July 31st.

Twin Cities Orthopedics is a renowned center for orthopedic care, treating everyday people, alongside professional and recreational athletes. This fellowship will, therefore, provide extensive training in musculoskeletal clinical experiences and surgical procedures.

The faculty is composed of orthopedic sports medicine and team physicians working in collaboration with one another and with our medical partners in the office, in the training room, on the playing field and in an educational setting, with a commitment to the pursuit of clinical excellence. Education and research are integral to the commitment.

Current Fellows

Nathan Jacobson x

Nathan Jacobson, MD
Nathan Jacobson was born and raised in South Dakota and comes here by way of South Dakota Mines for undergrad, University of South Dakota Sanford School of Medicine Medical School, and the Mayo Clinic for his orthopedic residency. He is married to his beautiful wife, Breanna, and they have two daughters (Emery and Ivy), and are expecting another daughter in November. Nate enjoys his role as a “girl dad” and spends the majority of his free time with his family doing outdoor activities. They have a mini-golden doodle, Bridger, who doesn’t miss a beat with family activities. They are looking forward to their year in the Twin Cities before returning to Rapid City, SD to begin his practice in their hometown.



Erik Slette x

Erik Slette, MD
Erik Slette was born and raised in Moorhead, Minnesota. He attended Moorhead High School, where he met his future wife, Morgan. They attended Concordia College-Moorhead together, running cross country and track. After college, he attended the University of Minnesota Medical School-Duluth. Following his second year of medical school, Erik and his wife moved to Vail, Colorado for a year, there he worked in the biomechanics lab at the Steadman Philippon Research Institute while his wife taught third grade at a local school. He completed his last two years of medical school at the University of Minnesota-Twin Cities before moving to Austin, Texas to complete an orthopedic surgery residency at the University of Texas-Austin. In his free time, he enjoys running, hiking, skiing, and spending time with his family. Erik, Morgan, and their four kids, Anja, Christian, Soren and Bode are thrilled to be back in Minnesota and to be joining the Twin Cities Orthopedics Family for a year.


Educational Experience

Our fellowship values and supports professional development by ensuring our fellows participate in:

Sports Medicine fellows function, with supervision, as team physicians for local high schools and colleges. The fellowship also provides exposure to the care of professional athletes from several different sports teams as well as other world-class competitors.

A Week in the Life of an Orthopedic Sports Medicine Fellow

“I am extraordinarily fortunate to be receiving advanced training from world-renowned faculty in orthopedic sports medicine here at Twin Cities Orthopedics. My time is spent in the clinic seeing patients, in the operating room, working on the sideline or training room, and doing research.” 2020-2021 Fellow

In the words of our 2020-2021 Fellow, here is a weekly breakdown:

Research Studies & Publications

Faculty and fellows are dedicated to and highly involved in research throughout the year. Fellows are given dedicated academic time for research projects, data collection, and manuscript submissions. Fellows are encouraged to develop their own potential research projects in collaboration with faculty or to join in with ongoing faculty research projects. Our Research Department will support the fellows research activities with power analyses, statistical analysis and figure composition as needed. Fellows are required to participate in a research project and to submit to a peer-reviewed journal.

Faculty and fellows work collaboratively to understand the physical examination, plain and stress radiographs, and CT/MRI scans for the workup of simple and complex sports medicine pathologies. It is expected that this collaboration will lead to future interactions between faculty and the sports medicine fellows as they initiate their career.
