I was reading the top reviews and I was appalled. I have never had anything but great service at this office. The front office ladies are pleasant, the MA's are attentive and I could not love Dr. Casper any more unless he became family. He is literally the greatest. My son has been seeing him for 3 years and his allergies are now minimal and his asthma is completely controlled. I recommend Dr. Casper and Arizona Asthma and Allergy to every person I know. I am so grateful to have found them. People who complain about wait time; it's a doctor's office. Where do you go where you don't have to wait? I've never had to wait more than 30 minutes, regardless.
