Consistently recognized by AT&T for excellence in sales, customer service, employee development, and ethical business operations.


CSI has been named the Top Revenue-Producing
Distributor for Wisconsin in 1996, 1998, 2000,
and 2003-2008.

Communication Systems International, Inc. (CSI) was started as a Networking Group within a computer company formed in 1979.
The corporation was located in the Midwest with a customer base of approximately 3000 clients. The main responsibilities of the group was the design and implementation of Local and Wide Area Networks.

In the late 1980's, the corporation began representing Wisconsin Bell, now AT&T®, as a distributor of data and voice networking products. The corporation executed a split in early 1994 giving the internal division its own identity as a separate corporation under separate management.

We have been consistently recognized by AT&T® for excellence in sales, customer service, employee development and for ethical business operations. We were named an AT&T® Solution Provider Champion for the past 25 consecutive years.
