MSSi’s employees are strategically located throughout the state of Florida. We are right around the corner in most cases. Along with this we offer remote technical services; even complex OS upgrades can be performed completely off-site via secure internet access.

Our technical staff is made up of former IBM employees; each IBM Certified, with a long tenure of highly trained expertise specific to IBM Power Systems. When you engage with MSSi, you are backed by over a century of service expertise.
