I would like to express my sincere appreciation for Company outstanding support during the recent GWCC (USDA) Redundant Power Upgrade. Matt and his staff,   personal efforts contributed significantly to the overall success of the Redundant Power Upgrade project to the GWCC Data Center.

Their willingness and attitude, and the professional manner in which they conducted their business are greatly appreciated, and I would place particular emphasis on the 16th June 2011, when I approached Matt with many question about his project and what was required for the success of this upgrade.
Matt, took the time to answer every question I ask in detail giving me a understanding knowledge of the task, devices and tools involved in the job.
I sincerely appreciate your Company commitment, and recognize your employees for their dedication. Congratulations on a job well done.
