We are a technology services company that puts people before technology. Yes, we have deep experience consulting, implementing solutions, providing managed services and staffing engagements. But we believe that, by focusing on relationships, we are better able to improve people’s experiences and lives through technology.
This human approach allows us to be more flexible, more attentive and, most importantly, to do the right thing. It also means we empower our experts to go beyond cookie-cutter solutions and create the tools that will move our clients’ businesses into the future.  Linkedin

Prosum Reviews

Write a Review

With Prosum, every person at every level treated us with respect and compassion and thoughtfulness – a lot of words you don’t use in the world of IT. It’s an IT services company with a heart.
We’re able to cover a broad gamut of technologies. Most companies can’t afford a part-time Exchange expert, a Citrix expert, a SQL expert and so on. But with our services, they can.
There are very few things more important to the health and stability of my company than who is holding the keys to my IT services…from the entire onboarding process, to the calls, to all the little things and the big things, top to bottom, left to right, its been a really great experience.

Sue Chen, Founder & CEO at NOVA

With Prosum, we ended up finding one of those rare win-win scenarios where you have not only better service but also reduced cost of technology…I’m a big fan.

Dan Deleon, CFO at The California Endowment

Prosum was the only company we were comfortable working with because they not only had a deeper level of Microsoft and deployment technologies knowledge, but they also demonstrated a stronger understanding of what we were trying to accomplish and how to accomplish it.

Keith Winston, Sr. IT Analyst at City of Garden Grove
