About Us

Establishing industry-wide standards for DME/CRT repair technicians through industry collaboration

About Us

The DMERT Group is a non-profit certification body tasked with setting the benchmarking for durable medical equipment and complex rehab repair training standards through industry collaboration. Industry members engage to establish a clear set of guidelines as to what is expected of DME/CRT industry repair technicians, how to evaluate if individuals meet the requirements, and provide means of educational support for those who fall short of qualifying. This initiative and certifying body have a foundation of open transparent industry collaboration, including technicians, providers, manufacturers, and other industry members.
