In my 66 years I have been to a number of allergists, and most were very fine doctors. However, I find Dr. Leyko to be a few steps above all the others. He is simply the best allergist I have ever had. He is very friendly, a good listener, and extremely intelligent. Unlike many health professionals, he is also very approachable, down to earth, and genuinely friendly. I trust him to do what is best for my health, and I haven't always reenable to say this about other physicians. A great physician, and a terrific individual! I highly recommend him!

His staff is friendly, helpful, and very professional. They make getting shots as pleasant an experience as is possible, and that is a strong statement!

Having allergies, I always have to go for allergy shots, and every single time I am in this office, I experienced a great staff. Highly recommend Dr. Leyko and his staff.

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 was able to not only diagnose my walking pneumonia, but also treat it and still help me manage my allergies. He has done more for me than any other doctor, including specialists! I highly recommend Dr Leyko! He saved my life!

My wife was breaking out in an all body rash and hives accompanied by facial swelling. We had been to other M.D. Allergists and I didn’t feel like their responsiveness was on par with my wife’s symptoms’. At other doctors we got frustrated because there were no MD emergency appointments, only emergency scheduling with Physician Assistants. Immediately upon meeting Dr. Bart Leyko, I felt that we had finally found someone that could help us. He welcomed us into his office and had my wife start explaining when she first started encountering her symptoms. Throughout this entire process, he listened intently, explaining his thoughts in non-medical terminology. There was never a sense of being rushed, but more of a genuine concern to ensure her symptoms were under control while he diagnosed and tried to determine a possible “root cause”. He met with us for over one hour and have since been contacted about some other testing to help him diagnose the illness. I cannot say enough positive things about this doctor and his willingness to listen and explain a treatment option. I’m very grateful that my wife is under his care.

Being a lifelong asthmatic, have come to know a number or allergy doctors in the Phoenix, Az. area. Dr. Leyko is, without a doubt, the best of the best in his field of medicine. He is a kind and compassionate person who genuinely cares about his patients. Definitely a man of character. Definitely a MUST visit for anyone with serious allergies.

Dr. Leyko took the time to get to know my daughter and my concerns. I was not rushed in and out or pressured to do any un-necessary testing. He also gave us several samples of the prescriptions prescribed which was very helpful. He is very caring and took the time to check in on my daughter after our initial appointment. I highly recommend him!
