About the Program

About Our Program

Nationally Recognized for Innovations in Sleep Medicine

With its pioneering history and forward-thinking approach, the Sleep Medicine Fellowship at Hennepin Healthcare trains the next generation of sleep specialists in all aspects of sleep-wake and circadian disorders, including sleep neuroscience, parasomnias, hypersomnias, sleep-related movement disorders, and sleep-disordered breathing in cardiovascular and pulmonary disease settings.

Our dual-site program delivers a wide spectrum of patient diversity and clinical experience. Fellows rotate at dedicated sleep clinics within two of the region’s largest academic training hospitals, Hennepin Healthcare and the University of Minnesota-Fairview. Fellows work side-by-side with staff who are leaders in the field and passionate about teaching. Together, we are actively re-envisioning how we can innovate care delivery in sleep medicine.

Our program was founded in 1977 and ACGME-accredited in 2005.


About Our Curriculum

A Forward-Thinking Approach to Sleep Neuroscience

The Sleep Medicine curriculum provides a comprehensive education in clinical sleep medicine for adults and children, with emphasis on sleep neuroscience. As an academic healthcare system, we maintain a well-earned reputation for our collegial atmosphere and supportive environment that fosters learning and discovery. Our forward-thinking approach emphasizes multidisciplinary collaboration, hands-on clinical skills, and the latest technology, all to deliver exceptional patient care.

We collaborate with the University of Minnesota’s Center for Magnetic Resonance Research to access the latest imaging technology for sleep medicine research. Fellows evaluate, monitor, and treat sleep disorders with cutting-edge equipment, including remote access to polysomnograms, and new home polysomnographic recording and interpretive equipment. Both sites incorporate the EPIC electronic medical records system.

We enthusiastically support scholarly activities and research pursuits of our fellows. The Minnesota Regional Sleep Disorders Center has a long history of discovery and innovation and participates in a number of ongoing clinical trials. We are actively investigating REM sleep behavior disorder and its relationship to Parkinson’s disease, as well as other parasomnias.

“The fellowship training I had in Sleep Medicine was singularly the most beneficial year of medical training in my career.  Understanding the role that sleep plays in the many capacities of human physiology and how, through Sleep Medicine, we may help patients through our knowledge was an incredibly rewarding experience.  The staff was nothing short of spectacular, and second to none.  I was well prepared to step into my role as a sleep physician and excel once training was completed.”

What Sets Us Apart?

History of discovery.

Hennepin Healthcare researchers were first to recognize several common sleep disorders, including REM sleep behavior disorder and its link to Parkinson’s disease, and sleep-related eating disorder and its relationship to restless leg syndrome.

Complex cases.

The sleep center draws national and international referrals for complicated conditions and rare disorders. Fellows gain hands-on experience evaluating and treating patients with severe conditions.

Patient diversity.

Fellows care for patients from across the spectrum of ethnic and economic backgrounds, with healthcare needs at all levels of severity. Rotations at the University of Minnesota include patients from across a large hospital network. Both sites feature comprehensive pediatric experience.

Post-fellowship opportunities.

More than 100 physicians have received advanced sleep medicine training at Hennepin Healthcare since our program was founded in 1977. Our alumni hold clinical and research positions around the world. Since 2005, 100% of our graduates who have taken sleep medicine board exams have passed.
