About Opus Fidelis
A general contractor built on discipline.
Opus Fidelis Inc. is a licensed California general contractor based in Carlsbad. We build and renovate luxury residences, commercial properties, and skilled nursing facilities throughout Southern California.
The name means “faithful work.” That’s the standard we hold: do what we said we’d do, on the schedule we committed to, and build it to last.
We’re a veteran-owned company, and it shows in how we run a job. Every project has a clear plan, one point of accountability, and crews who take pride in the details. Because our HVAC, electrical, and plumbing teams are part of Opus Fidelis, the people coordinating your project are the same people doing the work.
Our healthcare experience means we know how to work inside a building that can’t shut down. We plan around residents and staff, protect air quality and life-safety systems, and keep facility leadership informed at every step.
Leadership
Trevor Mock, Founder
Trevor Mock founded Opus Fidelis on a simple idea: a general contractor should be disciplined, accountable, and able to stand behind every trade on the job. He built a veteran-owned company that keeps HVAC, electrical, and plumbing in-house, so the team that plans a project is the team that builds it. Today he leads work on luxury residences, commercial properties, and skilled nursing facilities across Southern California.
