Nathan and his staff are outstanding! The only issue I have is that it takes 2-3 months to get an appointment with him.

Doctor Lebak was very knowledgeable and attentive to my concerns.

Very lovely gentleman who was willing to hear me.

Very caring

Dr. Lebak is an excellent allergist. Aurora is extremely lucky to have such a physician on their staff. I would highly recommend him to my friends and family.

Dr and his whole staff were awesome. They answered all my questions and were very polite and friendly. Good experience. Thank you all.

Dr took time and is very busy morning to do a phone check in with me which is all we needed to resolve the problem I had and it worked out best for both of us.

I like knowing other options that he shares with me about my health when making decisions. He is efficient, welcoming and on time!

I love Dr Lebak. He has improved the quality of my life immensely.

Dr Lebak is awesome and so is his nurse
