Excerpt from Letter of Appreciation from Elliot Hospital, Director of Facilities Management...

"I would like to take this opportunity to thank you for your support and cooperation during the electrical shut-down and replacement of a critical electrical transformer we recently experienced. The complex nature of this process could not have been done smoothly if it were not for your timely response and willingness to have this task completed in such a short timeframe.

Being able to accomplish this procedure so quickly without overly affecting patient care is largely due to the team effort between your crew and our technicians. Your assistance is greatly appreciated."
