Twin Computers streamlines your workflows, automates your processes, and trains your team to be more productive, all with the tools you already use.














Twin Computers was started in 1991 by Robin Fiddle Posnack and Mandi Fiddle Bergenfeld, twin sisters with a background in education and a passion for technology.
What began as a computer training company in the early days of DOS and Windows has grown into a full-service productivity consultancy serving clients across the country.

Most companies already own the software they need to operate at twice their current speed. The problem usually isn’t the tools. It’s how they’re being used.
We uncover inefficiencies, streamline the systems you already use, and equip your team with processes that improve productivity long after implementation.
From Microsoft 365 and Power Platform tools to CRMs, legal software, and custom applications, we help your technology work together as a single, efficient system.
We help organizations across industries improve efficiency, modernize workflows, and get more value from the tools they already use.
There’s no upsell, no licensing pitch, no product to push. We work exclusively with what you already own.
We learn how your business operates, then design corporate technology training around your actual workflows, your actual data, and your actual pain points.
We take what’s complex and make it clear. Your team won’t just learn new features. They’ll understand why those features matter to their day.
Seven steps become two. We don’t stop at training. We change the way your team works.





We were drowning in manual processes and didn’t even realize how much time we were losing. Twin Computers came in, rebuilt our workflows in tools we already had, and trained our entire staff in two weeks. The difference was immediate.

What sets them apart is that they actually teach. Our last training vendor read from slides. Robin and Mandi sat with our team, learned how we work, and showed us things in Excel we didn’t know existed. We’ve kept them on retainer ever since

They took us from on-prem servers and Outlook 2019 to a full Microsoft cloud environment. Our team was resistant to change, and Robin made it painless. I’ve never seen a smoother technology transition.

Based in New York and available nationwide, Twin Computers has been helping organizations work smarter since 1991.
