Satisfied Clients are our greatest Reward

Successful Small Business Server Migration to SBS2011

"We have been a client of Computer Systems Support & Design for over 12 months now. CSSD has met our expectations and more. Whenever issues occurred they have always reacted in an expedient, friendly and professional manner doing whatever it takes to ensure we are running efficiently. IT is a key part of our business and their support is vital to our future growth plans.
CSSD has successfully implemented for us improved network security, a Small Business Server Migration to SBS2011, and a migration from on-site Exchange to Office365 for our 35 employees.
We are happy to recommend CSSD to anyone looking for an efficient IT support partner providing great customer service."
Cesar Carcia CFO, Premier Graphics, Stratford, CT

Client Testimonials Fairfield County, CTMicrosoft Office 365 Supported

"The Zucco Company of Wilton, CT is happy to recommend Computer Systems Support & Design and the Microsoft Office365 solutions. Our sales office can be very chaotic, but Johannes was able to transition us from our web mail server seamlessly. Whenever any networking or computer problems come up, they are attended to promptly and with great care. It is refreshing to work with a vendor who promotes procedures and processes along with products and services. In fact, we view CSSD as more of a business partner rather than a traditional vendor/customer relationship. Furthermore, they've shown us how to use Office 365 technologies so that our staff are highly productive no matter where they are located. Thanks for all you do!"
Jack & Debbie Zucco, Wilton, CT

Complex IT Project Integrated













"It is an absolute pleasure working with Computer Systems Support & Design. 
The team at CSSD took a complex and problematical IT project involving an old Microsoft Small Business Server, Microsoft Exchange and our aging inventory management Line Of Business (LOB) server and applied their expertise and insight to identify the issues. They then set about solving our problems, methodically, purposefully and with great creativity.
The result is superb - beyond our expectations!"
Vic Mulaire, President, Cricket Hosiery, Bridgeport, Connecticut
