What Our Clients Are Saying About Our Services
Eric
Services Industry
The best IT provider is the one you never have to see. LeadingIT came out to make corrections to our system on day one and I haven’t seen them since because we don’t need them. They are managing everything behind the scenes and if/when we need them they have the problem fixed immediately….Perfect!

We were not looking for an IT consultant, we were looking for an IT partner. Even better, LeadingIT has become the HPD’s IT “department”. They are a call or click away- at one flat monthly service rate plus cost-effective purchasing power for computers and related equipment.
Mike
Consulting Firm, LeadingIT Client Since 2015
LeadingIT is awesome, they are very knowledgeable and quick to help when we’re having issues or even just need clarification on something. They have a team mentality and aren’t afraid to pull their thoughts together to help deliver exactly what we’re asking for.

We engaged Stephen and his staff over 6 years ago to take over day-to-day IT and help desk management. LeadingIT is a professional organization that takes the hassle out of keeping our workstations updated and network secure. They get the job done each and every time.
Elizabeth
Consulting Firm, LeadingIT Client Since 2015
We are very impressed with the LeadingIT’s service, attention to detail, support, response time and professionalism! Our team is incredibly happy with everything. The system that LeadingIT has to submit issues and questions is super convenient and the follow-up and time to get issues resolved is quick and efficient. I would recommend LeadingIT to everyone.

What a great bunch of people to work with. They are a young motivated, innovative group with the drive to keep our company up to date with the leading edge of technology. Dependable, reliable, and fast problem solvers on many levels. I have had the pleasure to work with Stephen and his crew on a daily basis and have the confidence that whoever answers the call, I will be taken care of in a fast professional manor. Kudos to Stephen and his company.

I worked with Geovel with 2 separate issues at work. He addressed our issues quickly to a positive satisfaction. While he addressed the issues, he had me stay on the line with him to answer questions he had. He even taught me a couple things, too!
I've worked with this company on a few issues now and haven't been left unresolved, or disappointed. 2 thumbs up!

Geovel was incredibly helpful with my issue. I had difficulty with Adobe software not working correctly. Shortly after I reached out regarding this issue, I was contacted, and Geovel worked on the issue professionally and swiftly. After spending hours on my issue, he figured out a solution that allowed me to use my program as it had before the issue. Leading IT really knows their stuff, handles issues with technology with a high level of professionalism, and at the end of the day, helped me get my work done. I couldn't recommend the service enough.
(If you have any issues, make sure to ask for Geovel, he's a kind, very intelligent, and patient person.)
