“All you need to know is that Eric, Dave and the rest of the team exceeded my expectations on this last project that they did with us. This was a big push project with a very quick time frame and it was completed perfectly.”


“Just a FYI. RSM was the highest bidder (out of 4 bids) on the SM package but failing to produce is not an option here, so I am going to award to RSM for First Class service on this one.”
