I would like to thank you again for the excellent job on the lighting upgrade projects you managed for our Riverview Elementary and Valleyview Middle Schools. From the outset of the project, you kept me informed of every step and were extremely flexible in performing work within the tight deadlines. Your persistence and honestly in designing a project that would get us the best results is greatly appreciated.

I've seen a savings of about $450/month since the project was completed. This was a no brainer. I've spoken with other business owners and pushed them to do the same!
