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 would have completed them on the same day, but my insurance only covers tests on separate days. In between visits, I had to stay off antihistamines in order to do the allergy tests. The doctor gave me a free water and small dose of medication right there at the clinic to relieve the itchy rash on my eyelids. I was really impressed with the level of care. The only downside of the testing is that the environmental and food tests only test for allergic reactions not food sensitivity. Nonetheless, I would recommend this allergist!

I am a small business owner with less than stellar health insurance and a VERY high-deductible. I found that Valley Allergy is in my network. I sent them my insurance information and made an appointment. I wanted two allergy tests - one for food and one for environment. I was told I needed to split them into two different appointments. I got my test results and left happy, until....I received my bill: Two allergy tests: $1760 ($880 each) Office visit #1: $492 Office visit #2: $268 Total Cost: $2520. My insurance picked up a portion of the cost, but I was left with a total out-of-pocket cost of $933. When I called the office in shock, I wanted to know why they did not warn me when my insurance did not cover such high (and in my opinion), ridiculous costs? I spoke with two different individuals who offered me no assistance. They stated they do not run insurance in advance unless asked. They weren't rude but they weren't helpful either. So, I write this as a warning to small business owners or anyone with a high deductible. Ask the office staff what they charge before you go in for an appointment. DO NOT make the same mistake I made.

His medical assistant treated us very poorly from the beginning of the appointment. She repeatedly interrupted us while we were answering her questions, rolled her eyes and made annoyed facial expressions throughout the interaction, and snapped at us for forgetting to list a medication on the paperwork. At one point, she simply walked out of the room while we were still responding to her questions. I understand medical burnout can be real, but taking that out on your patients is unacceptable and you should be ashamed of your behavior ma'am. The doctor was equally dismissive and seemed to make assumptions based on a prior medical condition rather than actually listening to our concerns. Much of the appointment turned into an unnecessary lecture about weight loss, drug use and vaping, despite us clearly explaining that we do not use drugs. We left feeling judged rather than cared for. My husband, who already has severe medical anxiety, left and stated he never wants to go back to the doctor because of this experience and how horribly he was treated. What was especially frustrating is that no testing was done for allergies or sleep apnea, despite these being concerns discussed with our primary care doctor prior to the referral and mentioned to the medical assistant. Although it says "allergy and asthma clinic" they don't do any allergy testing or treatment, as we were very curtly told by the medical assistant. Overall, the entire experience felt unprofessional, dismissive, and lacking in basic compassion. Don't waste your time or hard earned money to get care here.

I was so anxious to go to my appointment. I was seen by Dr. Keelin Schwartz and boy let me tell you…read moreshe is so amazing!!

I've had so many bad experiences with doctors in the last just trying to rush me out of there, but the fact that she took the time to answer my questions and walked me through everything meant so much to me, seriously!! Thank you so much Dr Keelin!!

Dear Dr. Joshua Yorgason,…read more I would like to take a moment to express my sincere appreciation for the outstanding care and professionalism I received during my first visit to your office. Stephanie, NP, was exceptional. She was highly professional, an excellent listener, and made me feel truly heard and taken seriously. She addressed my concerns efficiently and thoroughly, getting straight to the point while ensuring I felt comfortable and informed throughout the visit. After living with this condition for 45 years, it is incredibly reassuring to finally have clear answers and a well-defined plan to address it. Vivianna, the Medical Assistant, was equally impressive. She was welcoming, attentive, and did a fantastic job assisting with my care. Her professionalism and positive demeanor made the experience even better. I would also like to recognize Leah from Operations, who promptly stepped in when a piece of equipment was not functioning correctly. She resolved the issue quickly and efficiently, ensuring there was no disruption to my visit. Her responsiveness and problem-solving skills were greatly appreciated. Phil, Operations Specialist and Manager-in-Training, did an excellent job as well. He was professional, helpful, and demonstrated strong leadership and customer service skills throughout my visit. In addition to the exceptional staff, I must commend the office environment. This is the cleanest medical office I have ever been in, which speaks volumes about the standards and pride taken in patient care. The front desk team was also wonderful--friendly, organized, and welcoming from the moment I arrived. Overall, my experience exceeded my expectations. I would highly recommend this office to anyone seeking professional, efficient, and compassionate care. Thank you all for making my first visit such a positive and reassuring experience.

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.
