As a first time mommy, it was a no brainer as to who I was going to chose as my son's pediatrician. Dr. Markouizos was also my pediatrician and always made my visits happy ones. He's kind, gentle, smart, reliable and truly one of a kind. I honestly did not realize how great he was until I saw him with my own child who has severe allergies to dairy and soy along with laryngomalacia. He was able to root through the issues very quickly, and was always there to take our calls or immediately call us back if we were not able to get a hold of him. As 1st time nervous parents, this took a lot of our stress away. I highly recommend him for all parents with children. I promise, you will not be disappointed and he will always guide you with your child's best interests in mind.

Dr Markouizos is the most amazing doctor. He only has to look @my daughter and tell what is happening with her. I trust him diagnosing her. He found a rare heart defect that saved her life. You will not find a wonderful genuine doctor. He treatseveryone like his own children.

Dr. Markouizos has been my daughters pediatrician since she was a year old and now at 14 I wouldn't trust any other doctor with my "now" teenager! He is so thorough with questions and examinations Never jumps the gun with prescribing antibiotics which I value greatly. A true professional with a great bed side manner that any mom with the level of anxiety I have would truly appreciate.

We've been coming to Dr. M since before our daughter was born (almost 12 years ago). He is an amazing doctor who truly cares. You feel his genuine love for our family and the feeling is mutual. He is an amazing doctor. The highest recommendation.

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.

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.

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!!!!!!

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.

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. Dr Markouizos, thank you for being such a great doctor and taking care of my children all of these year (20+).
