Joel Weiss,

COO & Designer

Hi, I’m Joel.

I’ve been living and breathing commercial kitchens since I was a little boy observing my father Yermie, the founder of GSI Kitchens.

His kitchens kept calling my name. So when I finally grew up, I began working with him. 
Today, my father enjoys a semi-retirement while I lead the company the way he taught me.

Yes, we’ve grown. There’s more action going on. 

But the way we run is still the same as it was in GSI’s early days.
Same service. Same honesty. Same skill.

And we still service the same kinds of companies.
Companies that 

  • Appreciate easy communication
  • Understand the meaning of true quality
  • And respect straightforward honesty.

We don’t cut corners at GSI. And neither do our clients.

Our Team:
Small but Mighty

Yermie Weiss,


After years of selling disposable goods to nursing homes, Yermie saw a huge need for skilled commercial kitchen designers and suppliers. He set up shop as GSI Kitchens and immediately began to win government bids for commercial kitchen supplies.

As the word spread about GSI’s meticulous work and unbeatable service, private clients clamored to hire Yermie.
Among GSI Kitchen’s first private clients were:

  • Ateres Avraham & The Continental Hall – luxury Brooklyn wedding and event halls
  • UTA Schools – large network of Jewish boy’s schools.

Yita Weiss,


Along with her husband Yirmie, Yita helped establish GSI Kitchens 29 years ago. She was intimately involved in every detail that made GSI renowned for service. 
These days, Yita specializes in helping clients with the finishing touches – the small wares that can make or break a commercial kitchen’s success.
