IT Support in Wallingford: Local Experts, Fast Response

The teams at Kelser are some of the most collaborative and professional

I’ve had the opportunity to work with in the past 15 years. They are kind, fair and exceed expectations across the board!

Friendly, efficient and attentive..We were at the end of the contract with a very large, difficult to work with MSP and Kelser was one of our choices as a new MSP. Lisa at Kelser was very patient and attentive to our needs while I worked to tie up loose ends with our previous MSP. Lisa put together a plan that was appropriate for our small (9 person) company. The time and effort that she put into our proposal and our specific requirements stood out against other prospective MSPs. When we signed on with Kelser - they were quick to move to help us meet transition deadlines. They made the transition from our previous MSP, much smoother than I was expecting it to be. That alone was huge!

Kelser assigned us a small team, all of whom we met face to face. They made it very clear what their roles were and who to contact for what. I met with each member of the team for various portions of the transition and it became clear that our tech issues were always going to be addressed by people who were familiar with our environment - (rather than our previous MSP with any number of technicians that I never worked with, whom weren't familiar with our systems, breaking stuff while fixing other things and then billing us for all their wasted time).

Kelser has been very efficient with their time and my time. We've been with Kelser for a few months and already I am VERY HAPPY with the level of service they've provided and with how EASY it is to work with them. I am regularly impressed by their professionalism and depth of experience.

The Kelser team is extremely knowledgeable, helpful, and sets themselves apart by creating strong relationships and putting people/ the customer first. I can’t recommend more!

Fantastic technology service provider with a dedicated and advanced service portfolio !

Kelser is an excellent partner, very customer focused and solution driven!

I’ve had a great experience working with Kelser Corp and their MSP program. Their team is extremely professional, responsive, and detail-oriented. From onboarding to ongoing support, everything has been handled in a very organized and thorough way.

What really stands out is how proactive they are—they don’t just fix issues, they actively monitor and prevent them. Communication is clear, timelines are met, and you always feel like your systems are in capable hands.

If you’re looking for a reliable managed IT services provider that takes security, performance, and client service seriously, Kelser Corp is an excellent choice.

We’ve had an excellent experience working with Kelser Corporation. Their team provided outstanding service and support during our new server installation and firewall upgrade, ensuring everything was implemented smoothly and efficiently. They have also played a critical role in guiding us through our CMMC compliance journey for government projects.

Their staff is consistently friendly, highly knowledgeable and professional. We look forward to working with them again on future IT projects.

I’ve really enjoyed working with Kelser. The team is professional, responsive, and easy to work with. Communication is clear and they consistently deliver great results. It’s been a smooth and positive experience overall, and I’d definitely recommend them

Great MSP with very knowledgeable staff! I worked with Brian and would recommend Kelser to any of my friends looking for Managed Services!

Kelser Corporation is a highly professional and responsive partner with strong technical expertise and excellent customer service. Their team is hard working and reliable.

Kelser provided much needed guidance in protecting our company from cyber attacks along with additional IT support needed for a mid-size company.

I play every year in the Kelser Charity golf tournament and always have a wonderful time. Lisa collects great prizes for the silent auction, I always come home with at least one unique item.
