Trevor started out as an employee of my company Rancho Santa Fe Technology-MCS in 2006. After obtaining his electrical contractors license, he became the responsible managing employee for the electrical side of the business, and went on to perform numerous electrical jobs within our contracts.
Now as the owner and operator of Mission Critical Electric I would definitely recommend them for all your electrical needs, ranging from hanging ceiling fans to building ground up mission critical data centers.
Mission Critical Electric has had a relationship with CBRE since 2008, while working on the Navy Marine Corp Intranet contract. Trevor and his MCE crew performed numerous electrical jobs throughout the entire western NMCI project, installing hundreds of network cabinets and the required electrical distribution in DOD server rooms for us.
I highly recommend MCE for their fast, reliable and cost-effective electrical work.
Since 2010, Trevor and Mission Critical Electric has performed a multitude of electrical work for me and my employer. Electrical projects ranging from $10K to $3.3M, located throughout the US and overseas on government and private properties.
From inside wiring to site electrical infrastructure, MCE has always blended and at times lead the construction team and set the pace. I would recommend Trevor and MCE to anyone interested in project focus, quality, and completion.

An EV charger needs a licensed electrician, because it usually means a new dedicated circuit and often a panel upgrade to carry the load. We handle the charger, the circuit and the panel work together, and pull the permit where one is required.
It depends on the amperage you are moving to, the condition of the existing service, and whether the utility connection needs changing. A 200 amp upgrade is the most common request. We quote in writing after seeing the panel, rather than giving a figure over the phone that changes once we arrive.
Not for quoting a defined job. We look at the work, then send a written scope. Diagnostic work is different, because tracing an intermittent fault is the job rather than the estimate, and we say so before booking it.
Our office hours are 7am to 5pm, Monday to Friday. Weekend appointments are available by request.
Contact us with the details of your project and we will come back to you with a written scope. For larger commercial jobs we review the drawings first before quoting.
