Dr. Demetrios Markouizos, MD, FAAP

We love how amazing, knowledgeable and smart Dr Markouizos is. I couldn't be more pleased with the service and care Dr. M provides for my kids. i am always able to get in for an appointment. He takes special time with his patients and remembers what matters. He's always on point with his diagnosis and takes that extra step not to do any unnecessary testing. Thank you Dr. Markouzious for taking such good care of my boys.

Dr. Markouizos is very attentive, kind and caring. He listens to our concerns and will not give up until he finds the root of the problem. I always recommend Dr. Markouizos to everyone who has children. He was my doctor and now my children's doctor. He is truly the best there is.

I have been going to doctor Markouizo since i was a child myself, and when I fell pregnant i knew i woud go to him right away for my daughter but i know i made the right dessicion when my daughter developed a milk protein allergy, he was the greatest asset to her care we could have ever imagined. he not only called me back at all crazy hours of the night but my daughter is 4 months old now i still have never bought formula because he has been willing to help me and provided us with all we need

He is a very comforting Dr, he is always caring on each patent. He is the best in Astoria!!

My daughter loves Dr. Markouizos and all of the doctors at his practice. Everyone gets high fives and fist bumps as we walk in and out. They are compassionate, fun, and most importantly they are very good at what they do. They are transparent and always happy to talk through any questions we have (and considering she's my first born there were and are a LOT of questions). We strongly recommend Dr. Markouizos to anyone looking for a pediatrician.

I've been a patient here since I was a newborn & I honestly never want to change doctors. Dr. Markouizos and the rest of his team go above and beyond to make sure you get better, are comfortable in the process of doing so, and get what you need. He is the most thorough doctor I've met thus far & I recommend this place to absolutely everyone.

Dr. Marqouizos is truly the best pediatrician in the world. He was mine and my sisters doctor when we were little, and now takes care of my children. I would not bring my children to any one else!!!! He explains everything in detail, he answers all your questions, he does not rush you out of the office ever! He truly loves all children and it shows when he is with them. So happy to have him as my children's doctor. His staff is also exceptional!!!!!!

The staff is very friendly and the offices are extremely clean. Dr. Markouizos is an excellent physician and treats his patients and anyone who walks through the door with care and compassion as if they were his own family.

We trust Dr. Markouizos a lot.
Always takes good care of my son, well or sick.
Even though we moved, we always come back to see him.

My experience with Dr.Markouizos has been amazing and we couldn't be more pleased with him. He is a very thorough physician and makes u feel very comfortable. Dr. Markouizos and his staff are wonderful!!!
