This letter is written as a personal reference for Bruce Callahan.   I have known Bruce for a number of years.  Myself as a Regional Manager for Plas-O-Matic Valves. Our relationship at first was strictly of a business nature.  Over the years, I have had the opportunity to get to know Bruce personally as well. Bruce is, in the true essence of the word, a gentleman.  His word is his honor, which is difficult to find these days.   I would know automatically that, if Bruce would say he would do something, he would Always follow up and make sure everything was complete on his part.  Integrity, trust, these are all words that I use to describe Bruce Callahan.  

I wish Bruce well on his endeavors.  I hope this letter will be considered in giving Bruce Callahan and his company Grey Wolf Services, LLC., a favorable response.

Sincerely,

Bruce Callahan and I have been business associates and friends since July of 1998. Bruce always took the time as a supplier to make sure we were totally satisfied with the product and service provided by him and his staff.  I have only met a handful of people in the supply business willing to go the extra time and effort to make sure you were satisfied.  As a friend he is more than willing to help in any way he can. I know Bruce and he would give you his last dime to help you.  He is a friend I would trust completely.
