“I went into health care because the human body is a work of art and is direct proof that there is an amazing God…I wanted to be a practitioner to be part of families and help raise/care for their children throughout their lives. I love the idea of the old family doctor who cared for both the children and their parents even if that just meant listening. It is this family concept that really excited me about coming to Chapin Pediatrics.  My family is my life, and Chapin Pediatrics wanted to get to know and embrace my entire family –  not just me.  This means the world to me.”
