In the Beginning

As our name implies, network design is our specialty. Founded as a sole proprietor in 1997, Network Design Technologies (NDT) has supported and empowered clients in various capacities over the years to help businesses reach technology goals and reduce hardware expenses. Joseph Ruffin founder and Chief Executive Officer of NDT started as a one-man IT specialist offering desktop support to primarily churches, and local community action groups, software/computer training, desktop and server support, and offsite data backup and storage management.

Data Backup and Storage

With the growing demand for business to be HIPAA and Sarbanes-Oxley compliant, backup and storage quickly became a niche for the company. At its peak, NDT provided 3 separate server collocations, with built-in redundancies, to operate small data centers running 24/7. Providing essential services to small law offices and doctor offices well before the widespread acceptance of cloud-based computing and systems management.

Telecommunications Networking

Evolving with the changes in technology and understanding the local demand for network wiring in the Philadelphia tri-state area, NDT started to gain traction in a completely different IT sector: telecommunications. Shortly thereafter the company would employ several family members and contractors to keep up with pulling network, VoIP, and fiber optic wires — all tested and tagged and NDT. The company would ultimately absorb the assets of failing competitors including their field technicians and client base marking the start of another growth transition.

Consulting and Solution Providers

Twenty years later, NDT has gradually expanded to operate a network of consultants and technicians in CT, DE, FL, GA, KY, MD, MI, MO, NC, NJ, NY, PA, RI, TX, VA and Washington, D.C. Our objective is to create a company in which everyone is a hands-on contributor that feels comfortable sharing ideas and opinions while delivering state-of-the-art integration of technologies to customers.

NDT is an 8A certified company headquarters in Wilmington, DE with satellite offices in Philadelphia, PA, and Baltimore, MD
