Built by someone who has been the owner in your chair
Sean Fullerton started his first managed IT company, eMonarch, in Tulsa in 1999, sold it in 2011 — and learned within fourteen months that selling was a mistake.
NSN Management is what he did with that lesson: a Tulsa-owned, owner-led company built to stay, serving owner-run businesses of 10 to 100 people the way he had always wanted to. A U.S. Army veteran, Sean has worked in small-business IT since the 1990s, co-wrote Special Edition Using Microsoft Active Directory (Que, 2001), was named to the Tulsa Business Journal’s 40 Under 40, and led NSN Management to Kaseya/Datto MSP of the Year 2025 and the Inc. 5000 2026 list. He does not solve tickets anymore — he steers; the in-house help desk in Tulsa does the solving.
