Message from the President
Our slogan, “We get the job done,” speaks volumes about why I founded 13ZERO3. My background as an electrical contractor working for GCs set the stage for my desire to fix what I saw was broken in the industry. Jobs were unorganized. Typically, paperwork was a nightmare. Subcontractors were often not paid in a timely fashion. I knew how to relieve the stress on project owners, GC, and the subcontractors. I founded 13ZERO3 in 2009 to solve the operational and management challenges of doing renovations and remodels.


As President, I serve as our visionary, providing strategic direction, leadership, and management. Under my leadership, since its founding, 13ZERO3 has achieved 250% growth, with defense contractor General Atomics, one of our most valued customers.

I would welcome an opportunity to speak with you regarding your next project. Email me at, call (619) 272-7556, or use the contact form at the bottom of this page.
