Trish Erwin is the Quality Improvement Manager for Family Health Services, a division within San Mateo County Health, where she guides the improvement work being conducted within the Division’s three branches of Home Visiting, Public Health Nutrition and California Children’s Services. Her work includes collaborating closely with managers, supervisors and line staff to use data to drive process improvements that lead to better services for San Mateo County residents.
