      Mario has been working with our company as a sub contractor for about four years now. His knowledge of‎ all things pertaining to the electrical aspects of our jobs is incredible. Mario goes above and beyond the normal relms of his work by making sure everything is done to our specs and to code. The jobs are well organized and his timing is great. We have never had to wait for the electrical on any jobs of ours. 


Would definitely recommend Mario and his crew to any potential client.   

Thanks Eric Winger.

      We recently hired Olivieri Electrical Services for work at our home. We couldn't be happier with the entire experience – from the initial site visit to prepare the estimate, all the way through to completion of the work. They were very informative on the entire process, and kept us involved with decisions every step of the way so the end result was exactly what we wanted. 


We very highly recommend them to anyone needing their services!!

      Hi Mario!  We wanted to say a big thanks to you and your team (Andy and Tyler) for the excellent work that you did in our home.  Everything was done with thorough planning and craftsmanship!  Thanks to great communication, we always understood what was happening and what the options were.  Our questions and requests were always met with a smile and professionalism!  We were especially impressed with how well the guys cleaned up each day - even vacuuming between the studs after drilling for the wiring!

We certainly would not hesitate to recommend you for electrical work and would be glad to have you back in our home anytime we have electrical work to be done!

Many thanks!
