What Our Patients Are Saying…

Dr Konz and Dr Wendelborn are amazing doctors. The kind of doctors that really take the time to listen and help. I have never been to a doctor who made me feel more like I was important. The staff always goes above and beyond to help with insurance and billing and they are always friendly and accommodating. I always recommend allergy and asthma associates to all my friends and family.
