In-House Computer Services, LLC (originally named Sampson and Lehmann Technologies, LLC) was founded in 2002 by a team of enterprise IT professionals with a passion for technology.  This passion led to the desire to bring innovations and services common in the enterprise world to markets that were often under-served or simply over-looked.  The ICS team began with a focus on the small office/home office (or SoHo) market.

After great success in the SoHo market, in 2004 the ICS team expanded its service offerings to include the medium-sized business market.  Along with this expansion came the new name and a new strategy focusing on providing small and medium-sized businesses with the feel of a true full-service "in-house" IT department.  This allowed customers to be more strategic with their technology and ICS to be more proactive in supporting it.

In 2008, ICS launched a promotional partnership with the Businertia Group (formerly AccountablIT).  The strategy was to meld the enterprise class experience of the ICS team with the enterprise class processes of the Businertia Group.  The strategy has proven successful and continues to drive both organizations today.
