"I recently had the pleasure of working with Ken at Ellison Electrical on a service panel upgrade for my electrical vehicle and completely rewired my new kitchen. Ken was incredibly patient, explaining every step of the process. He immediately understood the floor plan and installed everything to code. His attention to detail and knowledge was exceptional. The quality of his work is evident in every connection and fixture. The service panel upgrade was seamless, my kitchen looks amazing and now my home feels more secure and efficient. He was always punctual, respectful of my property. I highly recommend Ellison Electrical for any electrical project."
