Our offices are located at 188 Industrial Drive, Suite #208 in Elmhurst, Illinois 60126.  All aspects of our business are handled from this office.  This includes the recruitment and training of our security officers as well as the supervision and administration of each job.


InterTech Group, Inc., recruits the highest quality applicants and employs an extensive screening process to ensure the integrity of our service.  As a result of paying the highest wages in the area for security officers, we are allowed to choose the cream of the crop.


Initial training is given at the InterTech Group, Inc., training facility to orient the officer candidate into the role of a security officer.  This training is given to all new hires, including security officers with previous work history in the field of security.

We've encountered security officers with five and more years of experience in the security industry who have little or no understanding of what the job entails.   We believe training is critical, especially to new hires, so they understand the importance of what they are doing for you the client.

On-the-Job Training

Upon successful completion of the preassignment classroom training program, the officer candidate would participate in on-the-job training at your facility to fully acquaint the officer with your specific requirements.

All training, both classroom and on-the-job will be thoroughly documented and retained in the active employee's personnel file.  The quality of the training will be measured at each level by the administration of relevant testing criterion.

Consulting Services

InterTech Group, Inc., will perform training based on the need of the client.   The time and dates of classes will be determined on a case by case basis.

InterTech Group, Inc., can provide a training facility if the client corporation has no facility available.


InterTech Group, Inc., provides security surveys and vulnerability studies across the full spectrum of security and loss prevention areas.  We adhere strictly to the laws regarding affirmative action as directed by the State of Illinois and the U. S. Department of Labor.  All of our employees meet the licensing requirements of the Illinois Department of Professional Regulation.
