Good relationships make for good business and good business is built on trust. Trust is a product of reliability, competence, judgement, and integrity. Your team has exhibited all of the aforementioned qualities and is largely responsible for my selecting JJ White as Bethesda Project's HVAC service provider. Working with a company that I trust is very important to me and I have found such a company
– Angelo G. Sgro | Bethesda Project, Executive Director
In addition to the basic specifications for the project, your team frequently had helpful suggestions to improve upon the renovations' initial plans. Additionally, they were diligent in supervising all subcontractors that worked on the project. Subcontractors were held to the same work standards as the JJ White team. The end result of these efforts was that Immaculate Mary Home was transformed into a state of the art, modern nursing facility. I would highly recommend JJ White for the coordination and supervision of any project of similar magnitude

I want you to know how pleased I was with the performance of your company. The level of service and commitment to the work was obvious to all of us here. I personally was responsible for the pipeline job and could not have been happier with the result. The support all through the planning stages of the turnaround was top notch. The cherry on top was managing to do all of this work without even a minor first aid case. Kudos to you and your company, I look forward to working with you in the future.
