How we started
45+ years strong as an MSP and still growing...
Since 1981, Kelser has grown into a team of engineers and cybersecurity experts serving some of the largest organizations in Connecticut and across the Northeast.
We're family-owned, Glastonbury-based, and still built on the same idea — technology should work for people, not the other way around.
We still believe great IT support starts with listening, responding quickly, and treating clients like partners—not tickets.
And we don't stop at the office. Through our annual Kelser Charity Challenge, we've raised over $1.2 million for local causes — because being a good neighbor has always been part of the job.
