I have worked with this company over 32 years. There is a reason why they have lasted so long. Granahan Electric has always been there for me 24/7. Whatever emergency I have no matter what time of day, they have always been there right away. Their professionalism and quality of work is and has always been outstanding. At times I have worked next to their mechanics and have grown to know them personally.  Every single one is honest and trustworthy. I never have worried about leaving them alone in my buildings. I have always said “once you find a contractor that works hard and can be trusted, you stick with them.”  I will always use them exclusively.

Your attention to detail and dedication towards completing the work at hand were impressive. Your crew did an admirable job of handling the many electrical design changes which occurred. If not for your hard work and dedication, this project could not have been a success.
