company built on integrity, transparency, and technical excellence.
The Directors
Phillip Williamson - Director
After 19 years in the industry, Phil has seen it all—what worked, what didn’t, and what could definitely be done better. So he decided to do things his own way. That’s how NSS came to life: built on the idea of giving clients a service that actually makes sense.
Alistaire Rushmere - Director
Ali’s been leading teams and driving projects for years, so stepping into a director role at NSS was a natural move. He’s got a sharp eye for detail and a straight-talking style that keeps things moving. With a focus on doing things the right way, he’s all about making sure clients get the service they deserve.
