You’ve been there.
The shipment that’s become a headache
The endless automated bots before you speak to a real person.
↓The bid proposal that arrived 20 minutes late.
↓The filing deadline your carrier missed because they 'didn't realize it was urgent.'
↓You need a partner, not a tracking number. You want your time back and peace of mind the job gets done right.
That's exactly what Nassau delivers.
We're The Delivery Specialists.
Here's what makes Nassau different from every other option you've tried:
A real person answers when you call.
Our dispatchers are live 24/7 — nights, weekends, Christmas Day. When your deadline can't wait, neither can we. You'll never leave a voicemail and wonder.
You get a dedicated account rep.
They know your routes, your clients, and your preferences. No re-explaining yourself every time. No surprises on your invoice. Just results, delivered.
We treat every delivery like it matters.
Because it does. Whether it's a single legal filing or 50 daily mail stops, we bring the same level of care. Every shipment is a promise — and we keep ours.

On time. Intact. Confirmed. If you need proof of delivery, we've got it. If you need real-time updates, just ask. Our dispatchers are on standby throughout the day to answer any questions. You focus on your work. We'll handle the rest.
Don't Just Take Our Word For It
"Nassau has been our go-to for legal filings for years. They know every court deadline and they've never once missed one. That's not just a courier — that's a partner."

A Family Business With a Big Heart
Nassau's story began in 1985, when Willie Albert — just 28 years old and newly married — started a small delivery company in Princeton, New Jersey.
Over the next 40 years, he built something more than a courier company. He built a reputation. Willie knew every road, every back road, every courthouse address by memory. His customers called him for reliability. His team called him generous. He believed in giving anyone a fair shot — regardless of their background — and his door was always open.
In the summer of 2025, after 40 years as President of Nassau, Willie unexpectedly passed away. His legacy lives on through his daughter Anna and her husband Jimmy, who are honored to carry forward everything he built.
These days, Nassau runs with one excitable beagle, one defiant toddler, a baby on the way, and the same standard of excellence Willie set from day one.
Today, it turns out dispatching runs in the family… Willie would be so proud.
“Hello, Nassau Courier, how many we help you?”
Willie's Granddaughter, Age 4
We care for our customers, our team, and each other — with the passion and drive for excellence Willie
showed us by his example.
