DPR Construction, Orange County Electrical Contractor

On behalf of DPR Construction SoCal, we wanted to thank you for all your help and collaboration in the sustainable design and construction of our Newport Beach Office.
It has been such a wonderful place to work this last year and a half.  Enclosed is a certificate commemorating our LEED CI-Gold Certification. Thank you for all your hard work to get us here!

Orange County Electrical Contractor

Just a quick note to let you know what a class operation you run.  The UPS A change-out here was a seamless transition from concept to final commissioning.

The project manager was on top of the whole project and the field supervisors not only laid out and managed the job perfectly, they also had time to shoe-horn in the new UPS B battery cabinets.  All considerations were made to accommodate a very picky and demanding client.   

- CB Richard Ellis

San Jose Electrical Contractor

I appreciate all your hard work to complete this project on time!  I was impressed by the clear communication during the project and willingness to provide solutions to other issues that came up along the way.  The structure looks better than I expected and our customers are raving about it being in place.  It's been a pleasure working with all of you!

- City of San Jose

Los Angeles Electrical Contractor I'm not sure how many great guys can work for the same company but I wanted to take this opportunity to thank you for assigning them to our project.  Your manager's professionalism, personality and knowledge was an important asset to this installation, and SCE was more than pleased. 

- Perera Construction

Now that this project is wrapped up I wanted to say thanks to you and your crew for putting in the extra effort to help us make our schedule.  You did a great job of managing the site and delivering a quality product while complying with our safety standards and processes.  I was very impressed with how smooth the job ran, the level of professionalism and attention to detail throughout.

- Solar City

The bottom line was that these guys "just get it".  They are knowledgeable, skilled, and have good attitudes.  They don't hesitate to do whatever crazy request comes their way.  They are efficient, safe, and easy to work with.  They only have to be asked once, and if they say they will do something, they do it.
