I've been dealing with Arizona Asthma and Allergy Institute for over 3 years now, and while the…read moreactual allergy care and doctors are okay, their billing vendor/third-party collections system is an absolute disaster and borderline predatory. Every 2-3 weeks like clockwork, I receive yet another bill and a scary collection letter threatening my credit, even though I've called their office dozens of times, provided my credit card on file for auto-payments (multiple times), confirmed charges were processed, and received apologies each time: "We'll note it in your account and stop this." Spoiler: they never do. It's been the same cycle for three straight years -- pay the supposed balance, get assurances it's fixed, then boom, another collection notice arrives stressing me out and making me question if my payments are even being applied correctly. I've double-paid certain charges just to make it stop, but the letters keep coming anyway. This isn't "poor customer service"; it's incompetent, harassing, and makes you feel like a deadbeat when you're not.

I have very severe asthma. I went there on the recommendation of my pulmonologist at Arizona…read morePulmonary Specialists. I originally started out going to an asthma doctor in Illinois who was an allergy and immunology specialist for one of premier medical schools in Chicago. When I moved to Phoenix in 1996, I used an allergist my doctor in Illinois recommended. After 4 years, my allergist moved to Las Vegas. He suggested Arizona Pulmonary. I've been with them since 1999. I have been taking Fasenra since 7/2020, and my asthma dramatically improved. I even lost 180 lbs from not having to be on prednisone except if I got sick. Everything was great, I looked and felt terrific, until the Fasenra stopped working about 18 months ago. It wasn't sudden, but noticeable. My breathing got worse. I was wheezing and coughing more, which I blamed on a month-long stay in the hospital in 1/2023 due to double pneumonia. Nope. It continued to go downhill then finally dropped off a cliff. I was put back on high dose steroids, which triggered me eating everything in sight and at night, causing me to gain 55 lbs. I was taken off the Fasenra completely in February of 2025. I was put on a trial of Dupixant in late March, which worked great for my breathing almost immediately, but gave me every side effect in the book, also almost immediately, too. It was so damn frustrating. My doctor there, Dr. Mason, felt Dr. Manning might be helpful because he didn't want me to fail the last medication available, Tespire. Perhaps there was a systemic allergic response he could avert? I went there not expecting a lot. Wow-was I wrong!! The people in the office were friendly and welcoming. The doctor, Dr Manning, was amazing. I could even imagine myself going to him for my asthma if anything happened to Dr. Mason to make him leave the valley (as my last doctor there had done a few years ago. In all, I'm very pleased with the care I received from Dr Manning. I'm hoping he can get to the bottom of the allergic reaction I had to the medication and, perhaps, the downward turn my asthma has taken in the last 18 months.

The doctor and injection staff at Allergy, Asthma & Immunology Associates (the Scottsdale location…read moreoff Shea) have been great, and the treatment process itself has been convenient and well organized. Unfortunately, the billing department has been a completely different experience. "Incompetent" is the best word I can use to describe what I have experienced. I paid in full, upfront, for my entire allergy shot treatment plan as an out-of-pocket patient. I even received a discount for paying in full. Although at this point, I'm not sure it was worth the hassle. I have a receipt confirming payment in full, and the office has verified multiple times that my balance was satisfied. Despite this, I have continued receiving invoices for charges I do not owe - NINE so far and counting. I was also told several times that someone would call me back to confirm the issue was resolved, but no one ever has. They have had over a month since the first call and weeks since the second and third. At this point, I wish I could bill them for the amount of time I've spent dealing with their mistakes. I have contacted the billing department THREE separate times and was assured every time that the incorrect charges would be removed. Nothing was corrected, and I received yet another bill today. When I attempted to call for a fourth time, their automated system disconnected me. It is incredibly frustrating to repeatedly deal with billing errors after paying a substantial amount of money upfront and being told multiple times that the issue had been resolved. Great medical care is important, but competent billing and basic follow-through matter too. This ultimately comes down to honesty, integrity, accountability, and competence. Five stars for the doctor and the injection schedule. One star for billing. Management seriously needs to address this department.

Nice doc, nice staff, but they did nothing for my concerns. Doc said, "Well, I've never heard of…read morethat," and never addressed it. I paid co-pay, United Health Care/Medicare said that was all I needed to pay. The doc's office wanted another $50. I sent the billing dept two hand written notes about billing UHC again, which they ignored. The only communication from them is the threat of going to collection. The billing dept is inept, and the doc is unresponsive.

His reason being anytime we come, there is always a problem from check in to check out it's never easy. He is 100% correct. I said let's just see how today goes. We arrive to checkin and they mentioned doing a breathing test before seeing the Dr. I told them when I made this appointment this was to get information about a new medication, we did not want to do the breathing test. They said no problem they would make a note. When they called to confirm, I reminded them we did not want the breathing test. Again no problem we will make a note. At check in she said "we have you down for a breathing test and to see the Dr.". I reminded her we did not want to do the breathing test. The look on her face was awful, like I mortally offended her. She then tells us well if you don't do the breathing test there is going to be "a bit of a wait". Ok but we made it clear all along and yet it seems to be a problem. So needless to say they proved my son's point, and this will be our last appointment here.

She even managed to get me a next day appointment with Dr. Casper, which I was so grateful for. I went in suffering from extreme hives all over my body after being sick the week before and having what I believed was an allergic reaction to something I ate that caused my lips to swell. My primary doctor was unable to help and referred me here. The hives were absolutely miserable -- painful, uncomfortable, and so severe that I couldn't sleep for days. It turns out I wasn't allergic to any food. Dr. Casper explained that my immune system was in a heightened response after the virus, and in some cases the immune system can misfire and begin reacting to healthy cells, triggering severe hives and inflammation. Having someone finally explain what was happening and know exactly how to treat it was such a relief. The moment Dr. Casper saw me, he immediately knew what to do to help. He was knowledgeable, compassionate, and reassuring during a very stressful time. After starting the medication he prescribed, I finally began to get relief, and I have not had hives since being on the treatment plan. Thank you so much, Dr. Casper. You are incredible at what you do, and I'm beyond grateful for the care I received. My husband struggles with asthma, and we will absolutely be returning to this office for any future allergy or asthma needs. I highly recommend this office to anyone looking for knowledgeable doctors and truly compassionate care.

First, I received a bill for $50 which I was told covered the allergy skin test I had received. I explained to the billing department that when I checked in for my appt, I was told that my co-pay covered the skin test (the receptionist specifically stated this). I never heard back so I assumed that phone call had taken care of everything. However, a couple months later, I received another bill for almost $300 and have been receiving monthly statements for this "balance." I will never visit this office again. They clearly do not have their act together and the right hand doesn't know what the left is doing. Now I have to take time out of the things I have going on to call and deal with something that is due to their incompetence, not mine. Insanely frustrating.
