Managed IT services rooted in Southeast Wisconsin
A family owned Wisconsin team headquartered in Cedarburg, supporting manufacturers and businesses across Southeast Wisconsin since 1991.
Why TSR in Southeast Wisconsin
- Where we grew up. TSR was founded in Cedarburg in 1991, and many of our longest client relationships are in Southeast Wisconsin.
- Proven with regional businesses. We kept one manufacturer running after its only IT employee left and took a spin-off from zero IT to fully operational in three weeks.
- One team to go to for answers. TSR owns the outcome across your help desk, security, cloud, and vendors, so you have one accountable resource for technology instead of a list of providers to chase.
