Patient Reviews

Anyone who suffers from severe allergies should consider starting immunotherapy with Dr. Leyko, if they are a candidate. I can't say enough good things about this clinic!

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.

– Liza R

Dr. Leyko is fantastic! He spent a long time with me, helping me figure out a comprehensive plan for my allergies, asthma, and eczema - something other doctors tend not to do. He seemed to care a lot. I highly recommend him!

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!

As usual, I had another 5 star experience with Allergy Asthma Clinic. The office staff, nurses and doctors have always been helpful and professional.

Love Allergy Asthma Clinic. Have been patient for 21 years. Staff is professional and fun. Dr Couch is amazing. Highly recommend. Never feel rushed. All my questions are answered. Dr. Couch discusses my treatment plan with me and listens to and addresses any concerns I may have.

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.

Dr. Leyko is such a wonderful doctor. He listens and is so helpful, knowledgeable. And isn’t in s rush to get you through the appointment and in to the next patient. I truly believe he cares about his patients.

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!

– Judith R

He was AMAZING, actively listened to me and my concerns and I got treatment the same day. I’m so thankful for coming across his care and his team. Thank Dr. Leyko!!!

Overall great experience, highly recommended. Doctor Leyko was very friendly and took his time to listen to my concerns. He is knowledgeable in what he does. I am very pleased with the experience.

– Cyndie R

Probably the best ever treatment I received from them every single time I went for an appointment. I don’t know how or why but other places must learn from this staff on how to be the BEST in this line of work. All in all, I 100% recommend this clinic.

– Patient

I have been coming here since 2021 as I randomly found the clinic on Google. Dr. Layko is one of the best doctors and probably the most respected as well. He always made sure to listen to my issues.

– Patient

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!

– John S

Extremely friendly, knowledgeable, and took his time with me. He went beyond the usual solutions to look for other causes of my symptoms and gave me solutions to try. I'd highly recommend you give him and his practice a try.

– Kraig B

Dr. Leyko was great. Professional, polite, and very knowledgeable. Would definitely recommend him.

Very helpful! I’m traveling through and had to find an allergist. I read other reviews and was very happy with my own results. The front office staff was amazing.

– Kim C

The staff and Dr. Bart Leyko at Allergy Asthma Clinic are outstanding! They are all so kind and compassionate and it is obvious how much Dr. Leyko truly desires to help his patients!

– Laurie L

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.

– Matt C

First and foremost they were right on time they were very professional very kind explained everything well to me what to expect and what they are going to do. I’m very very happy that I got referred to this clinic for my GP.

– Sue M

Dr. Leyko is very thorough and informative. He listens and gives feedback. I trust his opinions and his medical thoroughness. It’s a great feeling having such a competent doctor caring for me!

– Mark P

Great staff and Doctor. One of the few that actually fixed my reason for being there. Nurses are great with working with people and always take care of me. Even spotted reactions before I do!

– Marcus D

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.

– Penny M

Dr Layko is an outstanding Physician. Personable, takes time to explain his diagnosis. Would recommend him highly.

– Mike K

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.

– Barry E

Dr. Leyko and Allergy Asthma Clinic definitely exceeded my expectations. From the front office gal, to the gal who administered the allergy tests to Dr. Leyko, I highly recommend this clinic.

– Susan T

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.

– Kathleen S

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.

– Staci B

I recently had a consultation with Dr. Bart Leyko for my asthma and allergies, and I couldn't be more pleased with the experience. The staff was welcoming and made me feel at ease.

– Veronica R

I feel like Dr. Leyko was the only doctor I have seen who truly gets it. I had went from doctor to doctor for several months. Finally, Dr. Leyko made me realize that my diet needed to change. I am on day 17 of this new lifestyle change and have noticed a HUGE improvement with my symptoms. Allergy doctors know their stuff!!!

– Erin N

Efficient, on-time, knowledgeable, down to earth. Best so far.

– KS

I highly recommend Dr. Leyko to anyone looking for a compassionate and skilled allergy and asthma specialist. Thank you for the great care!

Dr. Leyko has put together a phenomenal plan to help treat my allergies since moving to the Phoenix area. I am able to run, hike, and play golf.
