Two corridors, one practice
The named engineer is Avery Parker. Tennessee work is scheduled on 423-888-0252 from Suite 208 on North Roan. Western North Carolina work is scheduled on 828-484-1257. Same person, same stack — UniFi, SonicWall, Microsoft 365, Linux, and incident response — not a national queue with a local pin.
Counties we treat as regular coverage, not overflow: Washington, Sullivan, Carter, Greene, and Unicoi in Tennessee; Buncombe, Madison, and Henderson in North Carolina. If your closet is in Gray, Marshall, or Flag Pond, say the town — we will tell you honestly whether it is a same-day drive or an appointment.
Upper East Tennessee
Johnson City office. Typical same-day drives: Jonesborough, Elizabethton, Erwin, Kingsport, Bristol, Greeneville.

Onsite and remote support for Kingsport manufacturers, professional services, and offices that need a local MSSP instead of a national queue.

Coverage on both sides of State Street. Same engineer you reach in Johnson City — no offshore tier-1, no “we do not cross into Virginia.”
Greeneville, TN
Onsite MSP, UniFi and firewall work, and incident surge for Greeneville and Greene County businesses that are tired of waiting on a Knoxville or Charlotte queue.

Closest onsite coverage after Johnson City. Managed IT, wireless, and emergency response for Elizabethton, Watauga, and the valley towns.

Same practice as Johnson City — Avery Parker — with a Western North Carolina phone and onsite coverage for Asheville, Weaverville, Hendersonville, Mars Hill, and nearby.
Weaverville, NC
Same Avery Parker practice as Johnson City, with the NC phone, for Weaverville and north-of-Asheville offices that need UniFi, 365, or someone in the closet.
Mars Hill, NC
Onsite and remote IT for Mars Hill, Marshall, and Madison County — the same Avery Parker practice, on the North Carolina phone, not an Asheville-only vendor that never crosses the county line.
Hendersonville, NC
Onsite MSP, wireless, and incident surge for Hendersonville and Henderson County. Same principal as the Johnson City office — not a national queue with an Asheville pin.
