Doctor Markouizos is an excellent doctor and truly an expert at what he does! He has been my son's doctor since he was born and I only trust him. He is very caring, very knowledgeable and understanding and just an excellent pediatrician. I have recommended him to everyone I know and they are so happy. Thank you Dr. Markouizos for always taking care of my son and being amazing at what you do. read more

Dr. Markouizos has been caring for my kids since they were babies, and the service has always been excellent. He is patient, professional, and truly attentive. The care he provides is outstanding, and I trust him completely. Highly recommended! read more

I don't understand some parents, speak up if you're ever uncomfortable or have concerns. It can get busy, but the front desk is attentive and handles all of my questions swiftly. They even take their time on the phone answering my 10 questions. The nurses are also handle my children professionally and treat them their age. Dr. Markouizos and Dr. Chung always, always take their time. They make the kids comfortable with whatever is necessary to have done medically and mentally!! 10/10 for me! Oh! One more, the doctors always call back promptly if there's any questions or concerns :) read more

The front staff is helpful and follows up about things. But I really love this place because of Dr Chung. He's always so calm, so helpful and informative! A gem! read more

Dr. Markouizos, saved the life of my 17 year old son, again. He accurately diagnosed my son in seconds after his examination. Prescribed the appropriate medication, and followed up with several phones to me and a Zoom meeting, in addition to another follow-up. I went to two (2!!) ER's on consectutive days and my son was getting worse. My son was steps aways from severe Pnumonia. If Dr. Markouizos did not intervene, I cannot imagine what would have happended. To say I love him is not enough. He is a Hero, he is kind, responsive, understanding, I mean I cannot say enough. His staff is efficient, caring and eager to assist. His office immaculate. I have knownhim for over 27 years, after my first son was born, and he literally saved his life on numerous occasions. He is proactive. He doesnt have to wait to know what he needs to do. He is like magic. I am lucky to have him life for so long. I mean so lucky. Thank you Dr. Markouizos, if you only knew how many lives you saved and families you cared for. Love you forever and forever and your staff. read more

We have been going to Dr. Markouizos office for almost two years now. The front desk is friendly and efficient. There's no game of telephone and they follow through on requests without issue. This alone shows how well run the office is and how much they value their patients. Our main doctor was Dr. Brian Chung but depending on the day, we may see one of the different doctors who practice there. The doctors who we have seen are all very good but with different pros. Each doctor has listened to our concerns and addresses them patiently. The doctors are also very thorough and like to schedule follow ups to ensure your child is progressing if they are sick. They will also run tests to ensure an accurate diagnosis and prescribe medication for the comfort of your child. Some parents might not need this hands on approach but I like the certainty of knowing my child's diagnosis (even if it is just the common cold!). If your insurance coverage is not comprehensive or if you have high co-pays this might be something to consider. Pre-COVID the waiting area was often full and the wait could be quite a while (the downside of a popular office!) but during/post COVID, wait times have decreased dramatically as has the occupancy in the waiting room. They now also offer televisits which has been a great way to do any quick follow up visits without leaving home. After visiting another doctors office that is closer to our home, we realized how caring and personal this office is and that is truly invaluable. Hoping that this office always retains these great qualities! read more

I am the mother of 3 patients of Dr. Markouizos. I have been with him for the past 13 years. He has been by my side during scary moments and always makes me feel as if my children are his only patients. From the moment I call the office I am always guaranteed to be seen the same day with my three kids. I have never been denied an appointment. Dr. Markouizos makes you feel like family. He always makes sure to tell my children he loves them and personally calls to check up on them. His team is one of the best. Morena is always so helpful on the phone and always ready to greet you when you enter the office. Doctor Chung and Doctor Chen are also amazing as well. Your child will always be seen by the best doctors. I am a mother who will travel and research only the best for her children. This is where you want to be. read more

Dr. Markouizos, Dr. Chung, and Dr. Chen are amazing physicians!! My children have been with the team since my youngest was 3 years old. My oldest suffers from asthma and visits can sometimes be overwhelming. The doctors are caring and kind hearted. The doctors are intentional in their profession. I highly recommend them to colleagues, families, and friends. read more

My sons have been patients for three years, since we moved to the area; since reviews of Dr. M's practice were stellar, I'd hoped the experience would match, but sadly, this hasn't been the case. I may be an outlier here. But my sons have never actually been treated by Dr. M, although I can recognize him by sight; they have seen Dr Chang or Dr. Chen. They were okay doctors, but not the legendary Dr. M of Yelp. When my son had GI issues or eye issues, they wrote referrals for doctors in LIJ, places that were inaccessible without a car. The place is very busy; don't expect old-fashioned personal treatment, the kind once given by family doctors. It's a zoo with howling babies. The office has charged me $20 when my son needed some forms filled out to participate in a swimming team, and for copies of medical records. I don't think this is the norm; I have read that legally, they are not allowed to charge more than 75 cents a page, and at any rate, I would have been fine if they had sent them electronically, but they do nothing electronically. Recently, after I'd switched my sons' insurance plan to GHI, the receptionists dumped them as patients. Which would have been fine, except that the new practice in Astoria (Northwell's) needs their medical records to book an appointment, and though I have filled out forms and made phone calls, they still haven't faxed or emailed the records; I was told Dr. M has to close their file. Summer is approaching and my son needs his health record updated for a trip, but they are dragging their heels (it's been five weeks since my initial request). I will have to make an in-person visit to take care of this. Bottom line, the positive reviews, for me at least, have been misleading. The one positive thing I can say is that they have always been able to squeeze us in for last minute appointments. read more

Hands down the best doctor (& the team that helps him) ever! I've been coming here since I was a newborn and I honestly don't think I'll find a doctor who is thorough, honest, and genuine. He's always more than willing to go the extra mile for you, something you just don't see these days anymore. I've gone to so many other doctor's offices and nothing compares to this place. It's clean, the team of people there are friendly and nice, and all the doctors that work with Dr. Markouizos are also thorough. Anything & everything that's done here (test wise, bloodwork, examinations, etc) is always done with/for a purpose. Of course, your comfort & your child's comfort is of the utmost importance, and so is the diagnosis. So many other places have you wait 2+ hours, take 10 seconds seeing you, and don't even tell you what your exact diagnosis is. You'll never have that happen here, I can promise you that. I never wanna grow up if it means I have to eventually find a grown-up doctor. You genuinely feel cared for when you're here, that's always the best part. read more

Dr. Markouizos, is wonderful person inside and out one of best pediatric doctor in New York. He took good care of my kids for almost 27 years and the staff is always very helpful. I'm so happy that my granddaughter has been going to Dr. Markouizos, for the past 10 years. read more

Your healthcare information is simply not protected at this practice. Employees here (in particular the front desk lady with long hair) really can use fresh training and a course to understand HIPPA requirements. Also, from my personal experience, the front desk is inefficient and unprofessional. Don't rely on them putting in a referral when they need to or having someone contact you from billing when they say they will (and this no matter how many times they say it will happen). Lastly, I came to this practice because of the good name of Dr. Markouizoz. Unfortunately, I never got to meet him, and in fact have never seen him there. I was told he's only there a few hours a week. I wish I had known that before bringing my daughter here. read more

We started bringing our son here at around 8 months old. In under a year, we've been sent off with antibiotics scripts as many as 5 times for ear infections and sometimes just for "fluid in the ear;" a $400 oral steroid script (which I contested the need for, given the outrageous cost, and which the doctor eventually retracted after I questioned it); a $75 compound ointment (which was essentially an equivalent to hydrocortisone) when our son got HFMD. It's clear the office's M.O. is to elect for the easiest and most expensive treatments. Dr. Chung and Dr. Chen are script-happy, in particular; Dr. Tchao - who I believe is relatively new - is much more measured in her approach but we rarely get to see her. I do feel first-time parents can easily be taken advantage of here. The admin staff are also quite short and dismissive at times in person and on the phone. Granted this office is marginally better than others out there (we're in NYC after all), but I say parents should expect more from their doctors - do more research, interview as needed, and look elsewhere. read more

I have known Se Markouzios over 25 years. He's the BEST Pediatrician around!!!! I bought all of my children to him and continue to even though they are in their late teens and twenties! He has made himself available to us at all hours of the day and night, weekends, holidays....truly a caring, knowledgeable professional. He has become Part of our family. Our son is handicapped. Where other drs. Gave up, he gave us hope. Our son today graduates pre-med From Stonybrook. We are grateful. read more

The best doctor in Astoria.... I've known the doctor for about 20 years he took care all of my 4 kids

Front desk: very short, rude at times. They run the office like an assembly line with no concern about you. Waiting times can be quite long as well. Nurses/PA: horrible. They are students and don't have any idea what they are doing. If any of the measurements are off and you're freaking out (how did my babies head double in size in a month!?) then don't. They mess up on the reg Doctors: Like the nurses, the Drs seem pretty insecure about things. Every time I go I am given a referral to another dr or a kn ultrasound for something. It's starting to become stressful to go for just a regular check up. I really like Dr Chen however, she seems pretty comfortable with babies and diagnoses. I have been there less than 3 months and have decided to go to another pediatrician. I'm very disappointed because the location was perfect. But the place is not. read more

Dr. Markouizos is a wonderful, kind, and supportive pediatrician. I had the pleasure of being his patient 33 years ago! I just had a son and Dr. Markouizos was my first choice. I am glad he will be my son's pediatrician and I know he will do a great job. The office is clean, organized, and nicely maintained. The staff is very friendly and courteous. The doctors are approachable and thorough. My son has received several check ups and has received a course of all the necessary vaccinations. While getting the vaccine I was informed of the risks and possible side effects and felt reassured by their advice. COVID 19 precautions are strictly observed. Staff and patients wear masks and have to wash hands before interacting with one another. I feel very safe going to the office during this pandemic. I highly recommend Dr. Mark and his associates! read more

I had twins recently and this office was recommended to me by a few friends with kids. I'm glad I took their advice. Dr. Markouizos is a very understanding and compassionate man- very good with the babies. I've seen him a few times, but my babies main doctor is Dr. Chen and she's a sweetheart. Like Dr. M. - very good with the babies and also very confident in her words. Confidence in a doctor is very important to me. The staff is friendly and accommodating. I've come for appointments at all different times, but I've discovered that the best time to come is early in the day- it's the least crowded and the wait is short. So if you can get an earlier appointment- go for it. The waiting room is pretty big as well- so it's comfortable. The waiting area, as well as the exam rooms- are always immaculate. Very clean and always smells like baby powder lol Also very important to me- I've had to call and request to see the doctor the same day for issues with my kids and whenever I call- they fit me in that same day with no problems at all! I highly recommend this office! read more

We have been going to Dr. Markouzios for over 2 years after our son was born. His 2 older nephews get driven in all the way from Long Island after moving there a few years ago because of how personalized and accurate the attention from the whole office is. They are incredibly accommodating with appointments when our son is sick and we are happy to drive 30 minutes specifically to this office especially after we visited other Pediatricians in our area. We will continue to go there for years as well! read more

When we started looking for a pediatrician for our newborn son, I went with Dr Markouizos because of the great reviews on Yelp and his proximity to my home. I wish someone had warned me, which is why I think my review is important. I hope that parents who do not blindly accept whatever their doctor tells them to do and like to do their own research on medical treatments and preventative measures find it useful. Our issue with the dr was over vaccinations. It does not matter to me that he is a staunch supporter of the CDC vaccination schedule. That alone would never warrant this review. What i have a problem with is how irresponsible and unprofessional he became when it came to HAVING A CONVERSATION over the issue. When we started doing our own research on the number and types of vaccines routinely given to babies in the U.S. we simply wanted more information and options. At one of the visits, when he wanted to do the Hep B shot (for a disease that is transmitted sexually) and we declined, he said it was up to us... At the following well visit we met with a different doctor at the practice, who said we needed to do a combo shot at the 2 month mark. When we said we were still unsure and were looking for a vaccine schedule that we felt more comfortable with, he tried the scare tactic. I did not feel he gave me a chance to talk at all, but threw random information in my face, clearly from feeling extremely passionate about the issue. Still, not the problem. The problem came when he mentioned that we would not be able to return to the practice if we did not follow the strict vaccination guidelines outlined by them. As he was saying this, the child was crying and the time on my meter ran out, so I told him I could not finish the conversation and had to leave. I promptly followed up on the issue with Dr Markouizos, since he was our main doctor, and we were meeting Dr Gupta for the first time. I emailed him and asked if it was true that we could no longer use the practice if we wanted to hold off on some of the vaccinations. I also requested that if that were the case, we wanted the name of a doctor who would continue seeing us, since by accepting us as patients in the first place, he made a commitment to us. He responded coldly and said that basically since we disagreed on the issue, he could no longer accommodate us and would be mailing us a letter that states as much. I again emailed him and said that we would most definitely not want to continue seeing him, but that dropping us unexpectedly left us with no other doctor to go to should the child need medical care. I wanted him to help us find another doctor. He did not reply. The American Academy of Pediatrics is specifically against doctors dropping patients on the basis of their refusal to follow a set vaccination schedule. However, I believe they have that right. What I have a problem with is NOT being given the opportunity to discuss this with him face to face, and being dismissed coldly and abruptly based on something that REQUIRES A SIGNED PARENTAL CONSENT. What medical treatment is forced on a patient without either discussing it or offering other options? The vaccine debate has gone so far that doctors are forgetting what their job is supposed to be in the first place. I am happy that many patients like him, but for those like us, who may have a similar issue, I hope that now you are aware. read more

Dr. Demetrios Markouizos is a professional and a very well experienced/educated pediatrician. If anyone is looking for an excellent children's doctor, this is who you should be going to. The facility, staff and night service are very helpful, make you feel safe and give you a sense of relief to know someone is always available just incase your little one gets sick. When it comes to your children you as a parent, have Thank you read more

My little man has an important swimming competition this coming Saturday. It is his last chance to qualify for Junior's Olympic and he woke up congested with a sore throat and runny nose. He has trained so hard the entire year waiting for this day and now he is not feeling well. We rushed to see Dr. Markouizos for a rapid recovery. I have know Dr. Markouizos since my oldest child, almost 21 year old, was born and I am confident that if anyone can help my son is him. We got into his office, I explained the situation, he run all kinds of test to make sure there isn't a serious condition behind, thank God it wasn't. So he designed a plan with the proper medication so that my son can recover fast for Saturday. He also made recommendations to my son and myself to prevent this condition from recurring. While I am with my son, Dr Markouizos requested that my daughter comes to see him on Saturday to follow up on some consultation she needed but did not come back. What doctor does that! Nowadays doctors just see you and off to the next one. I have known Dr Markouizos for many years and his love and care for all of his patients is always there. Dr Markouizos, thank you for being such a great doctor and taking care of my children all of these years (20+). read more

Demetrios Markouizos, MD - Nebulizer treatment - Pediatricians Near Me - Astoria, New York

I wish I could say that Dr. Markouizos is great but he isn't. We were referred to him by another doctor and expected more. Unfortunately, we have always waited over 30m (what's the point of scheduling appts?) and our child got the flu from sitting in the waiting room (no air filters turned on?). If you decide to come here prepare for the following: Doctor Markouizos will only see your child for a few minutes and most of the time he will hand you off to another random doctor. Most of the appt is handled by nurses, interns and other doctors. He might be great for you but we prefer doctors that care enough to examine our child in a timely and organized manner. This doctor was a disappointment. :( Will have to find a different pediatrician immediately. read more

I don't really like to say negative reviews, however I feel it's nessary for people to know when it comes down to our chidren. This place is nosiey, chaiotic and disorganized. The doctor spends less than two minutes with my son and the rest of the time it's an intern. When he does come into the room, it;s rushed and he's just trying to shove any medicine he can on him. I don't feel that he really is concerned. It just feels like a business instead of true healthcare. read more

New address: 2849 37th Street Dr Markouizos and Dr Papaevagelou (aka Dr Nick) have taken care of our children brilliantly for just under two years. Children's ages are 10 mos and the older, just under 4 yrs. read more

I moved from Queens to Suffolk County and make the trip in with my 3 girls just to go to Dr. Markouizos. He is the only person I trust and his office is very accommodating and amazing. I value their opinion and guidance. Hands down the best pediatrician out there! read more

DO NOT GO THERE! I wish I listened to the other reviews before I brought my son here. I agree with the other reviews about the doctors in this office being all about money and not at all about your child's well being. They even check to see what insurance you have to see what other tests they can add on just to bill your insurance for for no real medical reason. read more

DR. M has been treating my two sons for close to 15 years. He is a very knowledgeable, compassionate and excellent pediatrician. He has a gentle soul and treats my children with utmost respect and care. I would highly recommend for new parents to interview a few doctors and I guarantee you will chose Dr. M! My kids never hesitate to go to an appointment because they know they always feel better after seeing him. They have also overcome their fear of needles since Dr.M and his staff know how to cope with anxiety related to this. Kudos to Dr. M and Pediatric Healthcare of Queens! read more

Dr Markouizos has always been my favorite but now I rarely see him there. There is new doctor that took over and I feel as if they don't do a good job anymore. read more

I am very glad that I found PHCQ and specifically Dr. Nikolas Papaevagelou. I was looking for a pediatrician for my unborn baby while I was pregnant so I made an appointment with Dr. Nick for a consultation which was free (Smart!) Dr. Nick is a very pleasant man. During the consultation, he answered all my and my husband's questions and I HAD quiet a few! He explained the process of the visits and contacted us with the billing to know in advance how things will work. After the delivery and during all the check ups which usually I schedule at the end of day, you'd think he'd be exhausted, Dr. Nick is always pleasant, caring and answering all our concerns and explaining everything to us. A number of times, i had to call to ask questions and Dr. Nick returned my calls in a timely manner or was asked to bring the baby in right away. The staff is friendly and the office is clean. I do recommend Dr. Nikolas as I trust him to be a great pediatrician for anyones child. read more

Dr Markouizos is an exceptional pediatrician. He is a highly ethical and caring physician. Dr Markouizos always goes above and beyond his ability to help his patients. He is not only an excellent physician but a great human being as well. He addresses all my concerns every time I have an appointment. He is such a caring doctor that after I left from my visit he called me when they closed to see if the fever came back. EXCELLENT DOCTOR! I would HIGHLY recommend him. read more

I will never, ever take my kids to this office again! I wrote the review few years ago warning many that all of the doctors in this office prescribe antibiotics so easily. My daughter was sick and instead of going to her doctor in the city, I decided to give this place a shot again. She was seen few days ago and even thought her strep swab was negative she was prescribed antibiotics for sore throat. I immediately knew that was just same old thing that they do in this office, I did however give her the antibiotic, because she was in a lot of pain and could not swallow. Two days pass and she is still sick, I go back to same office yesterday, she lost almost two pounds, and another doctor says to continue the same treatment. Well let me tell you, I went to see her real doctor today and she has Hand, Foot, Mouth disease. Doctor could not even understand why she was given antibiotics. I googled the images, and the little blisters and red spots she had in her throat ( that I pointed out at the visit) where clearly one of the main symptoms of Hand, Foot and Mouth disease. How can you miss that? Not one, but two doctors. Absurd!!! I will never go back to this office! read more

We finally switched after our previous pediatrician had refused to medicate our son's GERD for more than six months. I hate to think that my baby had to suffer that long for no reason. We switched to PHCQ and Drs Nick and Mark resolved the whole deal within a month. So grateful for their care! Also, their office is really nice and well maintained. They have a sick waiting room and a well waiting room which I had never seen before but is a great idea with young kids. read more

I've been grateful to have Dr. M as my kids' doctor for almost 20 years-from birth till the college years! His staff are efficient, courteous and thorough. Dr. M is extremely caring and follows up, day or night, whenever there's a health crisis. I find the doctors to all have an excellent bedside manner and make the kids feel respected and cared for, from the infancy years right up to young adulthood. Dr. M is cautious and would rather err on the side of being careful than be sorry that something went diagnosed or treated. For our family, Dr. Markouizos and his team have always been a trusted source of medical care and support. read more

Dr. Markouizos and his staff have been taking care of my 3 children for the last 15 years since they were newborns. They are patient in answering any questions and even follow up with a call at home when needed. The office is clean and wait time is reasonable! read more

Dr. Markouizos, Dr. Chung, and Dr. Li make a tremendous team. We travel all the way from Forest Hills, Queens to see him at Astoria. Wait time is usually a little less than 10 minutes. The front desk is extremely professional and know what they are doing. They are flexible with appointments, always willing to accommodate us in case we need to bring our little guy in for any unexpected visit. Our experience with all of these three doctors have been amazing. My wife and try very hard at making sure our son receives the best possible care available and upon interviewing with Dr. Markouizos and his team, we felt confident that we had found a great team of professionals who will take care of our son. We are extremely happy with them. read more

Dr. Markouizos has been a great doctor for both my kids. He is very professional and attentive. His staff is very helpful. The office is clean and new. We are very grateful for his work and experience with our kids. Even after we moved from Astoria we still have kept him as the kids Dr. it has been almost 10 years we are going to him. Thank you Dr. for being there for the late night calls and taking care of our kids when they were sick. I highly recommend Dr. Markouizos if you are searching for a pediatrician. read more

Aww, I remember Dr.Markouizos and Dr.Nick. They were my pediatricians. I'm now 23 and way past my child doctor days, but I still think about them because they were the best doctors I've ever had. I was a very sick child, my immune system is shot so I was in here every other week hooked up on a nebulizer for an hour and really taken care of. As I got older, I developed hypochondria and anxiety and they were very attentive and caring even though they aren't therapists. They arranged my first therapist appointment for me! They're great, caring guys and I wish they weren't strictly pediatrics because my doctors now suck, and when I have a sore throat now no one cares because I'm an adult LOL. Life is so much easier when you're a kid. Take your kids here! read more
