Tom Marshall

Tom Marshall


Director

Tom established DEM 25 years ago after a career as an electrician and mechanical engineering.  He saw a gap where commercial and industrial clients required more than a basic fire protection system.  He acknowledged the industry’s need for regulation, requiring qualified technicians, accreditations, ongoing training, and qualified fire protection specialists to service commercial and industrial property.

Tom works closely with Gary, sharing the same commitment to nurturing client and staff relationships and a passion for continually improving the company’s fire safety offering and elite customer service.

“In the fire game, there was, and still often is, a pretty poor level of service and commitment. Our customers are people who care. Larger corporations, educational facilities, and people who value a job done properly.” Says Tom

We remain committed to providing the highest standards of customer service and the most advanced fire protection systems available.
