I have been bringing my 5 year old triplets here for the last 4 1/2 years and every visit has always been a pleasure. The staff has always gone above and beyond to help especially when I came without my spouse. Dr. Mark is just wondefrul very attentive and excellent bedside manner.

As first time parents, we were very concerned about choosing the right pediatrician for our daughter. We consulted with a couple of pediatricians and are so happy to have found the practice that treats us like family! Dr. Markouizos and Dr. Chung are excellent! They actually spend time to listen and answer all of our concerns. They are very up to date and knowledgeable. They're never pushy and are always educate us of various way on how to care for our child. When my daughter had a fever, Dr. Chung quickly responded to our call, which is very comforting to us as parents. Their office is always very clean and professional. We are so happy to have chosen Dr. Markouizos' practice! I gladly recommend them to all of my friends and family. They exceed all of our expectations!

Dr. Markouizos is simply the best! He knows his profession and his patients very well. There is no one I would consider taking my children to other than him and his practice. I trust him and never doubt any of his diagnoses. His staff is very nice and professional and the office is clean and has a pleasant atmosphere. Even when the office is full of patients, I feel like my child is the only one here with the personal care and attention that is given. My daughter says, "I Love Dr. Mark!"

Pediatric health care of queens office where Dr Markouizo is supervisor has a great staff are very polite and very clean.The staff is always attending to the patients well being and Dr Markouizo is always available when you need him,I recomend this office highly,so very thorough with every detail and positive.

Dr. Markouizos has been my physician since I was born. He is a kind, caring, dedicated, and intelligent physician who goes above and beyond for his patients. I am one of four children, and when my youngest brother became ill one night, Dr. Markouizos waited for my mother to bring him in to see him, when at the time we were living a distance of 2 hours from his office. I am currently beginning Medical School myself, and I aspire to be as great of a physician as Dr. Markouizos one day.

Dr. Markouizos is my son`s Doctor and we respect and love him so much! He has been taking care of our son since he was 2 days old! We trust him 100% and he ALWAYS helped us, no matter when we call. I as a mother respect that and we as a family love him! He treat us as his family!! :)

whenever at dr. markouzios office i feel good. everyone takes care of us and ive been bringing my boys since birth. now they are teens and still coming. i love this place and wont change at all. thank you dr markouzios for all that you do.

Dr. Markouizos has been my children's pediatrician for 23 years. Although we no longer live in the Astoria area, we travel to his office as often as necessary (and at least once a year for well visits). We wouldn't think of switching doctors. His care, compassion and level of expertise are unsurpassed. Dr. Markouizos demonstrates a genuine interest in his patients. We love him!

wonderful and well caring experience with Dr Markouizos and staff as always. Sufficient and always available.

He has been our family's pediatrician for over 21 years. He genuinely cares for his patients and their parents and is one of the most loving people I have ever met. When my daughter was 1, she was having a severe allergic reaction. I called his office, he got on the phone right away and told me to bring her in his office right away. As soon as we came, he took her into his hands and within minutes, my daughter was back to normal. He is amazing and never forgets a patient- which is rare to find.

Each visit to Dr. Markouizos is wonderful. All concerns are answered with care for my families feelings. There is no other doctor that compares. I would recommend Dr. Markouizos to everyone.

You cant go wrong with bring your child to Dr. Mark! My friend referred him to me and I am so happy she did. He and his entire team has been taking care of my daughter since she was born. He came to the hospital to see her the very next day she was born. You cant ask for a better bed side manor than that. since them they have guided me every step of the way, ensuring that she is healthy. I am very happy with their service and care.

I started with Dr Markouizos 8 years ago with my first child. Now I am there again with my newborn. He is unbelievable. He is always attentive, caring and oh so knowledgeable. All my family and friends have him as their kids pediatrician. We all adore him.

Dr. Markouizos is always accommodating, he goes above and beyond for his patients. We have continued seeing him since our kids have been born and they are now 14 and 16. I can't see myself going anywhere else.

Dr. Markouizos, is very professional, knowledgeable, caring, loving and most of all detail oriented in the care of your child. He makes himself always available for his patients. He follows through with referrals. The office staff is accommodating and courteous. the office is extremely well kept and clean. we have been with him for ten years and would not trade him for anyone.

We happened to find Dr. Markouizos through a recommendation 19 years ago. My daughter at the time was born with some issues, and through it all, he has always been there for our family. He's more than a doctor. He truly cares; and will call in the middle of the night to check in and make sure she/he is okay. For anyone looking for a pediatrician, I can't say enough good things about Dr. Markouizos and our experience over the years. We are truly blessed to have found him.

After multiple visits to multiple pediatricians in the tri-state area and not being satisfied with the care, service and follow-up with doctors I have taken my son to that has all changed 2 years ago after I came across Dr. Markouios's office. I made an appointment and since than I cannot explain how content both my son and I. He is attentive,thorough, a professional and genuinely cares for each of his patients. We will forever have him as our PCP.

Dr. Markouizos is beyond impressive, not only in his pediatrics and diagnostics, but also as a compassionate child advocate. He is absolutely brilliant. He has created a welcoming practice and has been there for my son through thick and thin. There are no words to truly express our gratitude.

My daughter was diagnosed by the doctor at the age of 3 with Wilms tumor. She had no symptoms at all. Dr Markouizos was so thorough he didn't like how her abdomen felt. Memorial Sloan doctors tell us often how lucky we are to have such a great doctor.
