Spongejet Manufacturing Firm
Great Communication, Skilled Staff, Clear Recommendations, they give 110%

We joined up with PCG in the fall of 2011, they sold me on their attention to detail, skilled staff, and response time. The real test was when I purchased new business software for out golf course,I needed new servers, PC’s and remote usage at other locations. I was use to the blame game when it came to hicupps on new installs but not this time. From the front desk, management, engineers on, I had expertise all the way. Fantastic communication, attention to detail, clear recommendations.

Thanks PCG for a seamless move from Google email to 365

The email conversion is complete and it went off without a hitch.

I also wanted to let you know that Riley did an excellent job helping to complete the task without any issues.

Before the actual conversion, he was not only helpful, but always accessible to answer any questions.

When he came to the office to start the conversion, he did what he needed to do with our laptops and was happy to help with a few other questions we had that didn't have to do with the conversion.

He was polite, knowledgeable and professional.

Great job team PCG on our moves!!

I wanted to let you know what a great job Dan and Bill did for us during the move out and the move back.

They were very knowledgeable and helpful, which made a difficult time a lot easier for us. Both moves were seamless, with no problems.

Your successful coordination did not go unnoticed, either. Thank you for pulling all of the pieces together under challenging circumstances of our Office having to be shut down because of the water damage.
