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

Kelser’s charitable golf event is one of those rare combinations of purpose and people done right. It supports a truly meaningful causes.   What stands out just as much is the Kelser team—great people who consistently go above and beyond, volunteering their time and energy to make the event first-class year after year.

It’s also a reflection of the kind of partner Kelser is in business: collaborative, generous, and committed to building strong, lasting relationships. Proud to support an event—and a team—that leads with both heart and integrity.

Paul Fitzgerald

Honesty, integrity and a commitment to their clients and the community.. in the 3 decades I have known and worked with the Kelser organization I see these qualities in every thing they do.   Happy to give them a 5 star review

Erich B

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.

Jim Robbins

My company has been working with Kelser for the past few months and everyone I have come across has been highly responsive and knowledgeable. Lisa in particular is a pleasure to work with and so supportive. Very glad I found Kelser, it's hard to find companies like these nowadays. Keep up the great work and thanks for supporting my small business!

Peter Schauster

We have been working w/Kelser for the greater part of 10 years, and they have been a breath of fresh air when it comes to overall IT know-how and cyber security in the current age.  While we have our own in-house IT staff, Kelser has been instrumental in helping assist on both small and large projects, have been a backstop for day-to-day troubleshooting, and have acted as our vCIO for the last few years.  At every step of the way, Kelser has provided a professional and personal experience and I look forward to our continued collaboration and partnership moving forward.

Heather Flannery

As a small nonprofit, we are grateful to have trusted and professional partners at Kelser to keep our technology running smoothly. Over the last 6+ years we’ve appreciated their responsiveness, guidance, and the prevention measures they’ve put in place to manage our IT environment. With their expertise and support, our team is able to dedicate more time to our mission. Keep up the good work, Kelser!
