I just wanted to relay some really good feedback from a lot of the people that have worked with your company and your folks in the not so distant past.  Comparing the work ethic of your people with other companies that do similar work, they don’t hold a candle to you.  You have done very good work, and that is what I hear constantly. 

Thanks for pulling this off so quickly given the weather patterns changing making the work more difficult. Good job!

I have no doubt that JJ&A’s management of the project will result in successful completion of the planned scope.

Communication with JJ&A continues to be first rate, even after the company has grown to include several new project managers and support personnel.

JJ&A has excelled in managing safe projects, making safety the number one priority for its employees and all subcontractors.
