The Law Enforcement Embedded Social Worker Program began in 2015 with one officer and once social worker working in unincorporated Snohomish County. It has expanded over the past four years due to the success rates in helping people who are homeless, addicted, and/or mentally ill get off the streets and back to living a productive life. The program now serves unincorporated Snohomish County, Marysville, Monroe, and Arlington.
