How likely are you to recommend Dr. Markouizos?

(Select your rating)
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.
