Meet your electrician
Jerry Bilous is a Master Electrician with more than four decades of hands-on experience across residential, commercial and healthcare work. That history brings context to unusual faults, older systems and projects where the simplest-looking answer is not always the right one.
Circuit Science uses small, efficient crews and purchases materials for the work at hand. The result is personal accountability, lower overhead and advice based on what the project actually needs.
