Welcome to Eastern Missouri Alternative Sentencing Services, Inc. (EMASS)

EMASS is a privately owned company founded in 1991 by Founder and President, Michael L. Smith.  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.

A couple of years ago, Michael L. Smith, President at EMASS, decided to offer SCRAMx™ 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™ (Secure Continuous Remote Alcohol Monitor™) is designed specifically for applications in long term alcohol monitoring programs where abstinence is required, SCRAMx™ (Secure Continuous Remote Alcohol Monitorx™) includes a bracelet-modem combination like a home-arrest system. 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." Please view our website to find out more information about our services and the SCRAMx™ product.

ON our website’s products page, you can link to our partner page.  You can read about a new press release from SCRAM, a new study shows the prevalence of DUI recidivism.  The NHTSA conducted a study in April of 2015 focusing on technologies used to combat drunk driving.  Repeat offenders nearly eliminated their use of alcohol while on these devices. In one of two jurisdictions of the study, those who wore the alcohol monitoring bracelets for a period of ninety days significantly reduced the rate of recidivism.

“The data showed that wearing CAM delayed recidivism by up to 43% and that fewer than 2% of CAM users re-offended while being monitored.  Most notably, in Nebraska program assignment to CAM for at least 90 days was associated with 113% decreased rate of recidivism.”
