Who We Are

A Family-Owned Low Voltage Wiring Contractor

M-CO has been family-owned since 2003. Clients usually bring the team in when the low-voltage work matters enough that they want direct accountability, fast answers, and a contractor who can stay engaged through the entire project.

The company works across security, fire alarm, voice, data, and fiber. That range is what makes M-CO a strong fit for coordination-heavy jobs where several systems need to be installed, tested, and handed over cleanly.

Our Values

What Sets Us Apart

As a family-owned company, our culture and values drive everything we do.

Real & Visible Owners

You are not pushed into a faceless handoff chain. Clients know who owns the company and who is accountable when scope, scheduling, or closeout questions show up.

Long-Term Orientation

The work is approached with the expectation that the system still has to make sense after turnover. That means cleaner installs, maintainable infrastructure, and relationships worth keeping.

Financial & Non-Financial Goals

Reputation, follow-through, and client trust matter just as much as finishing the job. M-CO is built to protect those things, not treat them like optional extras.

Fast Decision-Making

Because ownership stays close to the work, decisions do not get buried in layers. That helps when schedules change, inspectors ask for something new, or a scope needs to be clarified quickly.

Innovative & Entrepreneurial

The team keeps adapting as low-voltage systems change. That matters most on projects where older buildings, newer devices, and practical field constraints all have to work together.

One-Vendor Coordination

Security, fire alarm, voice, data, and fiber are all handled inside one team. That gives the client one point of accountability instead of a stack of specialty vendors pointing at each other.
