Adrian G. Letz, MD

Dr. Adrian Letz enjoys the detective work involved in achieving relief from allergy and asthma, as well as the complexity of the immune system. His goal is to work with patients to help them live active lives, free of allergy symptoms, while minimizing medications through allergen immunotherapy (allergy shots). Furthermore, he is dedicated to the proper diagnosis and treatment of food allergy, as well as caring for people with immunodeficiencies to prevent recurrent, serious infections.

Procedures offered include:

• Allergy Skin Testing
• Spirometry (Pulmonary Function Testing)
• Allergy Patch Testing (Contact Allergens)
• Allergy Shots
• Oral Food and Drug Challenges 
• Biologic medications for asthma, urticaria (chronic hives), eczema, nasal polyps, and eosinophilic esophagitis

In his free time, Dr. Letz enjoys playing the French horn and is a member of the Julien Winds, Dubuque’s professional wind band. He is the parish priest of St. Elias the Prophet Greek Orthodox Church in Dubuque.
