Since starting allergy shots my overall health has improved. Dr. Leyko is knowledgable and explains my conditions clearly. He makes sure that I don't use allergy products that adversely affect other conditions. It is easy to make appointments and to obtain the shots I need.

Had a great appointment with Dr. Couch. He really took the time to listen to me and is wanting to help me. He didn't rush me out or anything like that.

Best experience at a Dr.'s office so far. Dr. Leyko was very patient and thorough. He took a lot of time with me and answered so many of my questions. I left there having answers. The entire staff was extremely friendly. I would and will highly recommend his practice.

My 1st interaction was 2010 and it was outstanding. My allergies have shifted and gotten worse. I didn't think twice and went back. Dr Claudia Gaefke is outstanding. We found out my new allergies and we have a plan of attack. My pollen induced asthma is back under control too. Definitely go here!

This clinic literally changed my life. Don't put off living even if you are allergic to everything but water. Just go talk to these guys. I have never been healthier since I can actually eat food and get my metabolism under control. Life is good. Thanks to this group of kind knowledgeable people.

Dr. Leyko and his staff were supremely professional. The paperwork I had to fill out as a new patient was only 3 pages long!!! Now to the real stuff-Dr. Leyko actually gave me the opportunity to speak and he listened! I KNOW! Asthma patients will know what I’m talking about. Not only that he ended up making sure I left feeling better than when I came in. Long story short if you have breathing challenges in AZ make an appointment! Sometime the Lord just rewards you for not giving up! Thanks Dr. Leyko!

After my initial inquiry about my allergies with Allergy Asthma Clinic, I knew I’d be in the right hands of people who provided great care. The team was responsive, articulate, and provided excellent customer service from the front desk to the consult with the doctor. I asked a myriad of questions, all which were answered thoroughly. They created a plan for me after testing, and I’m looking forward to starting treatment. I would absolutely recommend this company to anyone looking for great care and relief. Thanks to all at the Clarendon location.

I have been a patient of Dr. Bart Leyko since 2006. From the very 1st visit, where I was in medical trauma, he assured me I was going to be okay and I have been great under his care since then. You may think why such a long time? I have an extreme allergic condition and as such knew that I would be under his care for a long time. Not only did he improve my quality of life with his care and treatment but he is delightful to work with. I am forever grateful to Dr. Leyko for his life saving technique and care. I would strongly recommend him to anyone that is suffering from allergy/asthma and have recommended him on a regular basis. THANK YOU DR. LEYKO!

Dr. Leyko has done a great job helping my sinus condition. He is personable and easy to talk to. He is the only doctor that I have seen for my sinus problem that has given a proper diagnosis of my sinus condition. He determined I do not have allergies but a sinus condition that has to be treated differently and not as an allergy problem. Since I have been seeing Dr. Leyko my condition is under control and now I know why all the allergy shots and meds I took in previous years never worked. I don't have allergies but a sinus condition. I can recommend Dr.Leyko with confidence.
Five Star Patient Review Barry E.
I came in with a horrible rash. Never have I been allergic to anything until I moved in a new neighborhood. Where, we are near mountains and a lot if plants were blooming. My allergy specialist was amazing. I showed her the rash and my issues. I was given an allergy test that same visit. I was allergic to everything blooming. I was given a prescription and a medicated cream. Also, I found out I needed an inhaler. It's been since I was child. I was given a breathing test, where I had been compensating my breathing. I was extremely pleased with my visit. Thank you.
