Best work

Ferrum’s team is part of my company’s family – they know what’s best for my business now and for the future. All I have to do is pick up the phone and I know they’re here to help me with whatever I need. Our systems used to go down constantly before Ferrum came in. Now, thanks to Ferrum, we receive a monthly report showing us we made the right investment – increased up time and no more days of staff sitting around drinking coffee because our systems were off-line. They usually know about a problem and have it fixed before we even notice a blip – who can argue with that!

One word comes to mind when describing Ferrum’s team – excellent! I’ve never worked with a more professional IT firm and look forward to a long lasting partnership – they truly are a part of my organization. I don’t know much about IT, but I don’t have to my very own IT department is a phone call away.

Managed IT

We rely on our corporate web-based systems on a daily basis. Even though corporate takes care of the agent web portal, we’re left to manage our own office networks. We work all over and at all hours of the day and night. Whether in the office, telecommuting from home or a hotel room, linked via wireless at a coffee shop, it doesn’t matter – Ferrum is there making sure we’re always up.

I would like to say, that Chris did an amazing job, and it was a pleasure being able to work with him and Ferrum in general. This is the first time I have had the opportunity to work with one of you in the field, and I believe that you all do a great job.

Thanks from AAG

I just wanted to say thanks for doing such a great job with the installation, recording our greetings, and answering a million questions yesterday. We really appreciate the hard work. I don't have Chris's email address, but if you could extend our thanks to him too that'd be great.

The upgrade took about 6 months and it was a nightmare. However, Thanks to Jonathon Macias there was a light at the end of the dark tunnel. He was very professional and informative. It was a pleasure to have Jonathon come in today.
