Senior Analyst

The Massachusetts Executive Office of Health and Human Services (EOHHS) is the largest secretariat in MA state government, comprised of 16 agencies with over 20,000 employees statewide. EOHHS services directly touch the lives of slightly more than 1 in 4 residents in the Commonwealth — some of our most vulnerable children, youth, adults, and elders. EOHHS provides access to medical and behavioral health care, substance misuse treatment, long term services and support, and nutritional and financial benefits to those with low incomes. We connect elders, individuals with disabilities, and veterans with employment opportunities, housing, and supportive services. We steer troubled youth towards a more successful path and do everything possible to keep children in our child welfare system safe. We support individuals who are developmentally disabled, mentally ill, blind, deaf, or hard of hearing.
