  • To : Mr. John Berzanskis, AMS

    Dear Sir,
    This letter is in recognition of the recent work done by your employees @ the Shell Des Plains terminal, in support of the Fire Foam Piping Replacement Project. Your employees, Cesar Acosta, Walter Rubio, Jay Omalley,  Sean Cusack, and led by Tim Dircks, performed an outstanding job of not only welding ( on gasoline storage tanks filled with gasoline ), but the professional manner in which they went about accomplishing their tasks. Their attitude concerning personal safety while doing these tasks was greatly appreciated by myself and I’m sure anyone else involved in this project. The personal interaction between themselves and others involved in the project reflected in the most positive manner on AMS and Local 597. If circumstances arise in the future where I have the opportunity to recommend this group of men, I will do so wholeheartedly and without hesitation. It’s always a pleasure to work with professional people. Please pass on my thanks to these men, and my appreciation for a job well done.

  • Bob,

    Thank you very much for attending our party on Friday. We are very happy that you came and really appreciate your partnership with us this year. Rich has been great. We have make great improvements in the way that we run our operation through our partnership with AMS. We couldn’t have done it without you guys. Thanks again. Also, thank you for your personal attention to the account. Many contractors send someone to do the work and then you don’t hear from regional leadership. In our business, we depend on partner contractors to help us identify and fix problems as well as opportunities for improvements. We sincerely appreciate that you have remained engaged in our relationship. Finally, thank you for the kind Christmas gift. It has already made its way home where I plan to share with my family, especially now that my kids aren’t so little anymore and they’ll all be home.

    Merry Christmas and Happy New Year to the AMS team and the Dobbins family.
