Department and Faculty

As one of the largest medical specialties of its kind, the Division of Allergic Diseases at Mayo Clinic in Rochester, Minnesota, has a rich history as a leader in the research and treatment of allergic diseases. Specific clinical interests include bronchial asthma, rhinitis, sinusitis, immunodeficiency, mastocytosis, anaphylaxis and other allergic diseases.

In any given year, the Division of Allergic Diseases performs approximately 100,000 diagnostic allergy skin tests and delivers treatment to thousands of patients, both at Mayo Clinic and in cooperation with local physicians throughout the United States.

The division's long commitment to the research and treatment of bronchial asthma dates back to 1950 when, immediately after the discovery of glucocorticoids at Mayo Clinic, several allergy consultants were the first in the world to demonstrate the benefit of these medications in the treatment of allergic rhinitis and asthma.

Miguel Park, M.D.From the program director

Welcome! Thank you for your interest in the Allergy and Immunology Fellowship Program at Mayo Clinic in Rochester, Minnesota. We offer an experience balanced between clinical work and research — our graduates go on to careers in academic medicine and community practice.  

The clinical experience includes complex cases as well as bread-and-butter allergy. The research opportunities include patient-oriented and laboratory-based projects. 

You’ll have the opportunity to train with many seasoned clinical faculty (pediatric and adult) and research mentors. Most importantly, you’ll work in a supportive, team-based learning environment. 

We look forward to seeing you here.

Advisers and mentors

The Allergy and Immunology Fellowship draws its faculty from the staff of experienced allergists and immunologists at Mayo Clinic. Advisers are chosen for their commitment to teaching as well as clinical practice and research. Many have published and lectured extensively and are highly regarded in their fields.

Fellows have access to these individuals throughout the training period — with the opportunity to learn directly from some of today's best practitioners in allergy and immunology.

Visiting professors

Many prominent professors visit Mayo Clinic each year. They present their work during noon and morning lectures and participate in hospital rounds. Fellows are encouraged to take full advantage of these opportunities.
