This is my new electrician and will be for years to come. Punctual on his timing, quality work, excellent professionalism and a problem solver. I gave him a tough task of needing to install a 240v socket and then help me create a sauna in my home with hardwiring and older components. When there was a piece needed he would go above and beyond even going to grab parts not expected to be needed. Patient throughout entire process. A pleasure to be around. I was in my sauna within hours. Hard to find a guy like this
