Dr. Sey is the kindest most caring pediatrician I could ask for. He is encouraging, thorough, practical and complimentary. When he's on call, he returns calls in a timely fashion, calls back later to check on the kids, and even makes special appts when necessary. He's amazing. High recommend.

Dr. Sey has been attending both of my children for six years, and I recommend him to all. He has great bedside manners, very straightforward with everything there is no beating around the bushes. Visiting Dr. Sey is like visiting my parents he gives me great parental advice, and he knows medicine. I've had other pediatricians who has left me skeptical of their diagnosis or findings, but Dr. Sey will explain everything detail by detail. Excellent doctor as well as office staff..
