"As parents of a 6 year old, the last thing you want to hear is that your child has a chronic condition. Dr. Collier has been so kind and compassionate through this ordeal. His bedside manner is perfect for our little girl; he is a bit silly at times, always caring, and uses the right words so she can understand what’s going on. I couldn’t ask for a better provider for my daughter. We are truly blessed to be cared for by such a wonderful provider."
