Real feedback from leaders who trust their IT operations to OSG experts

We completely outsourced our IT department to Outsource Solutions Group, Inc. They handle all the security and critical patching to our infrastructure as well as all help desk support. We also procure all our hardware needs through Outsource. OSG is extremely responsive to our needs, handles tickets with care and timeliness too. We appreciate everything they do for us and would recommend their services to any business looking for an IT provider you can trust

Vice President Of Commercial Operations, Pharmaceutical Company

We started with OSG a few years back when we had issues with our former IT company. They were professional and quick to serve us. Since that day we have loved the relationship that we have with all the staff at OSG. Their customer service is outstanding. I wish we would have switched to them sooner and I would HIGHLY recommend them!

Director of Operations, Fox Valley Non-profit

Outsource IT Group has taken the time to learn our business, serve as a trusted partner, and provide a level of expertise that allows us to effectively allocate human resources to other critical services. In addition to providing us with technical and hardware support, the strategic quarterly meetings have helped us to grow as an institution through the implementation of new technologies and processes. Newly instituted services include increasing internet speed and stability, the pending implementation of RFID, and a successful transition to the Microsoft Phone System for unified communication. We would highly recommend their services to any organization looking for innovation and creativity.
