What our clients have to say
  • 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
  • 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
