Premier Allergy is probably the best medical group I've ever gone to. I see generally see a PA, Eileen, and she has been super helpful! For the first time, I feel like I have my allergies under control. She always gives me a few options for treatment and will take the time to answer all of my questions. They always have appointments available at convenient times if you work a 9-5 job. I really feel like I'm being cared for.

So glad I found this place. Dr Lattal took time with me, really listening to my preferences for treatment and is genuine & kind. Kinzie has been wonderful - taking time to talk to me and getting me on the right track to be & feel healthy. The rest of the staff has only been wonderful to me every week & super helpful. I have recommended this place to my friends and family with allergies and will continue to do so.

Asthma and respiratory problems were making everyday life nearly impossible so when he sat down with me for my first visit and gave me and my health HOURS of his time, I was certain I was in the best possible hands to lead me out of my crisis. Here I am a year later and it's like night and day...I am managing my asthma under his careful watch; exercising again; my immune system is stronger for the first time in years and I am about to start a series of allergy shots so I can ween myself off daily inhalers. Dr. Latall is THE MOST thorough, dedicated and authentically compassionate doctor I have come across in my 45 years of healthcare. He is the real deal. He and his staff exemplifies the IDEAL for health care in the 21 century, harnessing today's technological and medical advancements while showing their patients the warmth and humanity of an old, country Doctor. Thanks you guys for being you!

I took my 4-year-old for allergy and asthma test yesterday, and we both had a great experience. The staff and Dr. Latall are beyond friendly. Needless to say I was nervous for my daughter to go through all of the testing, but everyone made me (and her!) feel so at ease. There was some waiting, but it was worth it, and there’s nothing worse than feeling like a doctor doesn’t have enough time for you. I feel really fortunate that our primary care doctor referred us to this practice because it seems like the best of the best. Sarah S.
