John Van Wagoner, M.D.

Dr. Van Wagoner has been in practice since 1999 and specializes in adult and pediatric allergy, asthma and respiratory illness. Specific areas of interest include the diagnosis and treatment of allergy (respiratory, food, insect, and drug), asthma, eczema, respiratory illnesses, and chronic sinus disease.

“I chose a career in medicine because I love helping people feel better. My father suffered from asthma throughout his childhood and adult life, so I grew up seeing how this disease negatively affected his life. I understand that people with asthma or allergy problems often live with many bothersome limitations. In particular, asthma, food and drug allergies may pose life threatening risks. I believe people with these issues need effective and timely care. Using state of the art diagnostics and therapies, I can offer long-lasting relief to my patients with allergies, asthma and recurrent infections.

“It is such a joy to see people feel better because of what we do here at Southwest Allergy and Asthma Center. Our superb health care providers, coordinators and nurses carefully meet each patient’s specific needs. Taking time to listen and understand our patient’s issues guides our commitment to provide simple, written instructions for their care. We take pride in seeing our patients in a timely manner with minimal wait times for appointments. Furthermore, we schedule follow-up visits to ensure our patients are experiencing significant improvement and if needed, to tailor their therapy. Our entire team is compassionate and dedicated to our patient’s treatment. We take our role very seriously and treat each patient with respect and dignity. I am proud of what we do here at Southwest Allergy and Asthma Center and look forward to continuing to improve the lives of our patients.”
