About Allergy Partners
A Network Built Specifically for You
Allergy Partners was created to do one thing: Bring the highest level of care and clinical expertise to as many people as possible living with allergies, asthma and other allergic disease. After 40 years, and after caring for hundreds of thousands of patients, our focus remains the same.
“You’re really getting 150 allergists, not just one.”
Stephen Shield, MD,
Chairman of the Clinical Governance Board
What began as a community practice in Asheville, North Carolina, has grown to become the nation’s largest and most trusted allergy and asthma practice comprising 150 of the best allergists and immunologists in the country. Each provider in our network understands the importance of working together to solve any complex problem brought on by asthma and allergies. This shared knowledge enables us to bring world-class medicine and leading-edge practices to communities across the country.
What Guides Us?
Our guiding light is you, our patient. In every decision we make, we ask, “Will this be better for those that entrust us with their care?” This guiding principle flows through every aspect of our practice, enabling us to remove the obstacles facing so many physicians today so they can focus on what matters most–caring for you.
To learn more about how we can help, find your local office and make an appointment today. Together, we will ensure that you receive only the best.
“Our goal is to be the absolute best place for a patient to receive care.”
David A. Brown, M.D., Founder & CEO
We Set the Standard
We work tirelessly to remain at the forefront of clinical excellence and technological advancements because we are committed to helping our patients find lasting relief. Today, we have developed multiple state-of-the-art programs and facilities dedicated to this very goal that include:
- An evidence-based and standardized allergy immunotherapy program, developed by our physicians and delivered through our centralized allergen extract lab.
- A robust clinical research program to provide real world insights into the conditions we treat and provide patients with access to emerging treatments
- A comprehensive program for the diagnosis and management of food allergies.
- A centralized program to improve access to biologics and other advanced medications for the treatment of severe asthma, hives, eczema, and other allergic diseases.
Each program was built to empower you to live without allergies and asthma discomfort.
Our Story is Just Beginning

Duane Keitel, M.D.
Dr. Keitel’s interest in Allergy and Immunology began in college researching Tcells, an important cell in the immune system. A practice focused in the field of allergy seemed natural through his nine years of medical training. After finishing his Allergy training at Vanderbilt University, joining Allergy Partners at the Northern Kentucky hub in 2003 allowed him to practice in a family-oriented area to help care for both kids and adults.
“After a decade treating allergic diseases, the satisfaction of helping patients improve their quality of life by controlling their allergy symptoms is very rewarding.”
Originally from southern Indiana, the Cincinnati Metro area provides many exciting opportunities for entertainment, sport, and dining that were not available to Dr. Keitel growing up in the “farmland.”
