Arizona Asthma & Allergy Institute

"Met with Dr. Casper. He was patient, thorough and asked for my feedback. I really felt he wanted to help me get better. I wish all Dr.s were like that!"

"Dr Boesel has been taking care of me since 2017, when I developed a rare, life-threatening immune system disorder. Dr Boesel is one of the few doctors I know that, along with being crazy smart and a true expert in his field, is completely approachable and takes the time to listen to what is going on."

"This organization is incredibly understaffed. wait times in the office up to an hour and trying to get through to schedule is insane. took four days and four messages to get someone to call me back. (Update) Someone called me back today within an hour and possibly it was just a bad week when I had to wait so long from someone to call me back.. So much better! It felt like some of the like some of the prescriptions prescribed are just cookie cutter. I need to add that today Someone got back to me with an a couple hours to set an appt. Maybe that was just a very off day when I had to wait 4 days."

"The staff at AZ Asthma & Allergy Institute are top notch. They are professional and I was cared for with kindness and compassion. I have one word to describe Dr. Boesel - AMAZING!! I highly recommend Dr. Boesel as he is extremely knowledgeable in his profession, is an active listener and treats his patients like family."

"Great office staff and convenient location! Dr. Boesel is professional and listened to my concerns and answered my questions regarding an antibiotic challenge test. Nurse that administered testing was great and made me feel at ease throughout the process. Phone wait when calling for an appointment was way too long but Dr. Boesel assured me they are working on resolving it. Highly recommend the practice."
