Jeffery
Absolutely Impressed! Jeremy and the team are amazing. We can always talk to someone at the service desk when we need help and that's been HUGE for our team across multiple states. Yesterday, one of our team member's email accounts had been hacked and they were on top of it, shut down the threat, and had the account secured before we even knew what has happening. Super professional. Thanks guys! You're rock stars.
Patrick
A-Team! My firm has been a client of Jeremy Karmy and his professional support team for our I.T. needs. I have worked closely with Lucas who is super responsive and provides very clear expectations any time we are working on a technology project. The cybersecurity support is top-notch, with encrypted emails and 2-factor authentications that they recommend we have not had any issues. When these guys have a project to complete it gets done, timely, and clearly explained. Jeremy has built a team of solid performers who are passionate about supporting client needs and protecting their privacy. I would recommend contacting them today and getting them on your team.
Lorena
Amazing company and customer service. 24 hour IT assistance every day. Have taken care of all of my business needs. Highly recommend to small or large business owners. We would be lost without them. Thank you for all you do!

Having worked with them through my place of work for almost 3 years, I have never had a single experience that I wasn't completely satisfied with. Their willingness to help, attention to detail, and quick responses make working with them something to look forward to. I had the intention of mentioning names of employees to call out for great service, but the whole team is amazing and I don't want to leave anyone out.

We have been using DevFuzion for our IT support at the business I work for years. When we came on to this job we offered to bring in our own tech support as part of the contract but the owner declined. After working with them on various situations over the past 2 1/2 years I understand why the owner wanted to keep them. They respond quickly and proffesionally, even after hours. When we need replacement software or hardware I always feel we are treated fairly and with integrity. Thanks to you Jeremy and your DevFuzion staff.
