Customer Testimonials

We work with contractors every day, it’s part of our business being in the property management industry and the experience from start to finish working with everyone at Donnelly was nothing short of fantastic.

LISA MORRIS | ASSET MANAGEMENT | LANDEX

We would highly recommend both the Direct Install program, and Donnelly Energy to address any non-profit or for-profit business energy related project.

THE REVEREND SHARON E. CULLEY | PASTOR | SOMERSET PRESBYTERIAN CHURCH

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.

ERIC LARSON | DENVILLE | BOARD OF EDUCATION

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!

WAYNE HIGGINS | OWNER | THE 24 HOUR GYM

Thank you for a job well done! We love the new lighting!
