About Us

Located in the heart of California’s San Joaquin Valley, Fresno-based magnetar.us, inc. (MUI) is a premier electrical and electronic construction contractor.

Opening doors in 2007 as Sunrise Systems Low Voltage Construction, our founder, John Tapia, and fellow shareholders, David Sisty and Greg Hardin, quickly became the go-to subcontractor for local public works projects.

Focusing on alternate and sustainable energy as well as the technology systems in which the company is already well established, we have moved into federal contracting as a prime contractor. Over the years, MUI has worked hard to maintain a high-quality client base: Gamewell Fire Alarm Systems just one of the major manufacturers we have trained and certified for installations.

Our expertise in custom audio/video is especially sought-after, for projects including large video conference rooms and professional theater applications. Clients increasingly request mag_.us, inc. by name, and we are proud to say that our service is used as a specification standard.

Another area in which we surpass the competition in both expertise and price is complex access control and video surveillance systems.

“On time and within budget” is a mandate our project managers take seriously.

In 2012, our company was accepted into the SBA 8(a) Business Development Program, proof to us that we are moving in the optimal direction. Based on the technical nature of our current core capabilities, energy management and associated projects are a natural expansion.

Clients range from higher education to federal agencies; we have had the honor of securing the future of historical landmarks, as well as civil defense buildings. We offer services from initial design, through to installation and maintenance; no project is too large or small to be considered.
