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.

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.

I did these things because I had a great relationship with Dr. Erdos. He is kind, supportive, thorough and listened to all of my feedback about my care and the runnings of the practice. He was a fabulous partner is diagnosing and helping me manage a complex immune disease. At one point, he put me in contact with the CEO so I could help her troubleshoot where things were going wrong with patient communication. This year, things went even more downhill. I stopped getting calls back. Out of six phone calls, ONE was returned. I left multiple messages to get them to send the prescription that I needed. I left multiple phone calls about the patient portal that was broken and never heard from anyone. After I decided to seek care elsewhere, they contacted me to see how I was tolerating the new medication! The medication that they never sent in! And the person who called me referenced a note from a doctor that I do not and have never seen. I physically went there to get a copy of the prescription and then magically, the pharmacy received it! All of this further validated my decision to leave. I shouldn't have to work this hard. Neither should you.

There is no way to reach a person at this office because all phone calls are routed through an automated system with extremely long wait times.

I have no doubts as to the competence of Dr Erdos but the way the office is managed could be improved.

They won't do the skin pricks for food allergy testing if you were an adult at this facility because they say all food allergies are developed when you're a child. Then they will lecture you on the difference between food and intolerance and allergy. Lastly, you'll leave with a pamphlet on why testing for food allergies isn't a good idea if you are having gastrointestinal issues because of x, y, and z.

He also managed to tell me my sinus infections were migraines, not sinus infections because I have sinus pain when I get them. Find a different facility. Dr Davis is useless.

I told him I spoke with insurance in advance to do both food and histamine allergy testing for this appointment and had not taken any allergy pills for two weeks prior. He still refused. What was the point of our interaction?? Or to even be referred to this place if they don't do what they are established to do which is allergy testing?? I was perplexed and after he handed me a paper with random suggestions on it not even accurate to my situation, as he didn't listen to me the entire time.

I brought my own medical records and symptom history--but the back-office staff refused to review any of it. The allergist interrupted me repeatedly, minimized everything I tried to share, and essentially accused me of exaggerating or lying about my symptoms--even while I was visibly unwell in the exam room. Sadly, a family member of mine had a similarly disturbing experience at this same office. It seems they are not equipped--or willing--to handle patients with complex medical histories. At one point during my visit, after the allergist left and the nurse rushed out, I overheard him ask her within about a minute, "...they're still here?" I felt humiliated and walked out. The allergist questioned why I even came and made it clear he wouldn't help me. It was a traumatic and degrading experience. Their refusal to listen, document, or take basic steps to assess my condition is not just unprofessional--it's dangerous. Afterward, I looked at their Yelp and Google reviews and saw others report nearly identical experiences: being rushed, dismissed, and treated with disrespect by both doctors and staff. This does not feel like a legitimate allergy or pulmonary clinic. My family and I will never return. Please advocate for yourself and seek care elsewhere. Your health is too important to be treated like this.

There aren't actually allergy shot appointments despite them making you have an appointment it just goes by when someone checked in. It's a huge waste of time and a massive joke. The allergist I was seeing left the practice, I am routinely on hold for 30-40 minutes, get told they can't contact the pharmacy for medication delivery, and get billed for claims they submitted to my insurance (and the insurance paid). This whole practice is awful and I would suggest avoiding it if you can.
