“Dr Aughney is the best. Very good with both kids and parents. My kids never have a fear to go and see him because they trust him which is so important.”

Our family has gone to the Pediatric Center for decades. We have always been treated well by the friendly, knowledgeable staff. We love Dr. Anderson and Dr. Edwards especially, but all the doctors and nurses are fantastic! They are each compassionate and trustworthy. We recommend everyone to the Pediatric Center.
