About Nassau NDI Diagnostics, Inc

A company dedicated to protecting the health and safety of emergency service personnel.

Your Full Service Medical Team Since 1991

By providing convenient, affordable, efficient medical evaluations, NDI works to ensure compliance with state and federal health and safety regulations.

Established in 1991, Nassau NDI Diagnostics is the first medical screening service to provide on-site evaluations for firefighters and first responders. With over two decades of experience and a team of medical professionals, NDI has built long-lasting relationships with its clients. Communication and partnership are the foundation of NDI’s commitment to the men and women who protect and build our communities.

NDI is based in Long Island, New York, and proudly provides service to firefighters and emergency medical response units. Though NDI has a long tradition of serving the emergency response community, we readily offer the same service to any organization whose personnel require medical evaluation.

We look forward to utilizing our experience and expertise to ensure your staff pass important regulations and are certified to perform their duties.
