We came to Dr.. Marchlewski after my daughter experienced an unexplained instance of hives And edema. The Dr. Took the time to explain what was happening to her, possible reasons why, and exactly what he proposed we do to determine the cause...every step of the way I was impressed with his desire to ensure full understanding on our part as well as his desire to try his best to see, if possible, what may have been causing the reaction. We highly recommend Dr. Marchlewski.

Dr. Marchlewski came recommended to us by my cousin. Her son has multiple food allergies and Dr. Marchlewski has been caring for him for years. I am so happy we made an appointment. Dr. Marchlewski is knowledgeable and he took the time to explain things in a way I understood. We trust him and his staff to take care of our 7 month old son.

Excellent Dr. The nursing staff was also very lovely. I got there a bit late but it wasn’t an issue at all. I’m very much satisfied with this experience and would recommend him to anyone. His friendliness and knowledge of his work is definitely a plus.

I have nothing but great things to say about Dr. Marchlewski! He is an extremely knowledgeable physician and I will continuously recommend people to him. I truly appreciate how detailed and professional he is. It is important to me to understand my condition, the causes and how to work towards a solution. Dr. M is great at walking you through this!! I am currently on allergy shots therapy ...about two months in and I have seen significant progress as well. Totally satisfied with my care here!

Dr. Marchlewski was very confident in how he explained everything in clear detail. He was patient and took his time during my visit, I did not feel like I was being rushed out. I would highly recommend.

Was experiencing terrible burning in my head with face flushing. No MD could figure out why EXCEPT for Dr Marchlewski! He ordered a full blood work up only to find I was overdosing on Vitamin E. Once I stopped, all the pain went away! Love this MD!!!!! I always recommend him. Have to go back soon for some dermatitis from painting and spackling!

Dr. Marchlewski is by far the best doctor that i have seen. I highly recommend him.

03/22/2017 Monika S. from ZocDoc

He was very helpful. He called me after my son's appt (which he was with us for over an hour) and spoke with me for over a 1/2 hour. He never made me feel rushed.

11/04/2010 Patient from NYC

This guy knows his stuff very impressed with him and very hospitable.


Dr. Marchlewski is extremely knowledgable as an allergist; very gentile with children. My kids love his office and friendly staff especially when they give out stickers toys and lollipops. Very pleasant experience from check-in to check-out!


Dr. Marchlewski is a very thorough caring and knowledgeable allergist. He is very good with my son. I've been going to Dr. Marchlewski for a couple of years now and would highly recommend him.
