Eastern Missouri Alternative Sentencing Services

EMASS is a privately owned company founded in 1991.  We provide a variety of services to the courts and criminal justice system and individuals who are dealing with substance abuse related or other legal problems.  Our services include Private Probation Supervision, Pre-sentence Investigations, SATOP service for DWI offenders, Domestic Violence Counseling and Education Seminars, Driver Improvement Programs, Alcohol Drug Education Programs and traditional Electronic (House Arrest) Monitoring.

We have offered SCRAM Systems in numerous jurisdictions in Eastern Missouri. There is a critical need for this type of testing system which is ideal for problematic DWI/DUI offenders and other alcohol related offenses such as: Assault, Domestic Violence, or even Child Custody issues. SCRAM CAM (Continuous Alcohol Monitor™) is designed specifically for applications in long term alcohol monitoring programs where abstinence is required, SCRAM CAM includes a bracelet-modem combination.  The staff at EMASS believes very strongly that it is important to provide this type of technology to the Criminal Justice System in that this technology can potentially have a great impact on both the individual and public safety. Dealing with alcohol offenders usually includes a comprehensive program of sanctions, education, and treatment. The more information available to assess individuals and detect whether they are in compliance with their court-ordered mandates, the better the chance they will successfully complete the supervision and be safely reintegrated into the community.
