Dr. Grimes is the PI for the longitudinal study of Massachusetts’ “Mental Health Services Program for Youth” (MHSPY), via a grant from the RWJ Foundation. MHSPY is an internationally recognized approach to cost-effective treatment of children and adolescents with serious emotional disturbance (SED). It was financially self-sustaining through a uniquely integrated system-of-care that relied on shared goals and blended funding across primary care, schools, juvenile justice, child welfare and mental health.

Dr. Grimes obtained her MPH from the Harvard T.H. Chan School of Public Health and is a former Faculty Research Fellow at Harvard’s Kennedy School of Government.
