Meet Brad Grein

Electrician and owner of Grein Electric serving Kitchener–Waterloo–Cambridge (and ~1-hour radius). I deliver code-compliant, hazard-free work without cutting corners—pairing deep electrical theory with hands-on troubleshooting, careful planning, and clear communication. I started in residential renos and panel upgrades, ran a service truck early in my apprenticeship, and moved into commercial new builds where I led large teams of electricians. Experienced on projects including Google Kitchener, Mammoet Cranes in Aberfoyle and Vista Hills Public School in Waterloo and more. In industry, I maintained and improved complex systems at Hammond Power Solutions and Toyota Stamping (PLCs, robotics, overhead cranes), later training teams, managing drawings (AutoCAD/Electrical), and stewarding ESA Continuous Safety Services compliance.

Today I apply that range—problem-solving, document control, efficient job execution and customer listening—to deliver tailored solutions with quality materials and workmanship that last. My long-term goal: grow Grein Electric into the company electricians thrive in and clients trust for life.
