Sandra Fritsch, MD
I trained in the Triple Board Program in pediatrics, psychiatry and child and adolescent psychiatry at Brown University. With this training and “being in the right place at the right time”, I have had the privilege to work with pediatric primary care providers throughout my career; supporting the mental health care of youth in the primary care setting. I was in Massachusetts when MCPAP; the Massachusetts Child Psychiatry Access Program was developed and then started the Maine Child Psychiatry Access Program. Being the lead for CoPPCAP is an honor and an exciting opportunity. I have only been in Colorado for three years now and look forward to supporting our pediatric primary care providers throughout the state.
