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
In our quest to continuously improve patient care, Allergy Partners has partnered with B-FLEXION, a leading global technology and innovation organization. As a family-owned business with a long heritage of involvement in life science, B-FLEXION shares our desire to bring more advanced allergy care to people across the country.
This collaboration ensures that you and your family receive the most up-to-date treatments and resources while maintaining our commitment to offering compassionate, patient-centered services.
Looking to the future, we are poised to continue revolutionizing the way allergists serve patients and diagnose and manage allergy symptoms. As the leader in allergy and asthma treatment, we remain dedicated to developing and delivering the most advanced care available.
Physician Leadership
Christopher Copenhaver, M.D.
I initially moved to North Carolina to attend medical school at The University of North Carolina in Chapel Hill. After completing my allergy training at the University of Wisconsin and practicing back in my home state of Pennsylvania for 5 years, my family and I were excited to move back to North Carolina in 2009.
My interest in treating allergies and asthma stems from my personal experience as a patient. I have experienced firsthand the great improvement in quality-of-life patients have with proper treatment of their allergies and asthma. I believe that patient education and involving patients in making decisions are key components of medical care. By listening to patients and families, I work with them to develop an individualized treatment plan.
I care for patients of all ages for a range of allergic diseases and have particular interest in asthma, allergies, sinusitis and bee sting allergy. Outside of work, I enjoy mountain biking and hiking with my wife, who is a local family doctor, and our 3 children.
