What ASC does

All Source Co. is a San Diego-based private general contractor founded in 2003, providing integrated construction services to institutional, governmental, and commercial clients across Southern California. The company operates three interconnected service lines: General Contracting (tenant improvements, renovations, remodeling, ground-up builds, maintenance, and repair), Preconstruction Services (budget validation, value engineering, material selection, scheduling, and constructability reviews), and an in-house Finishes Division that self-performs paint, tile, flooring, wall coverings, coatings, polished concrete, fabric-wrapped panels, and architectural film.

The self-performed Finishes Division is the company's structural differentiator: by bringing finish trades in-house rather than subcontracting them, All Source eliminates sub markup, retains direct quality control, and offers clients a single point of accountability across GC and finish scopes. Notable delivered projects include UCSD Pepper Canyon Student Housing (580,000 sq ft), UCSD Theater District and North Torrey Pines Living & Learning Neighborhoods, UCSD Triton Center, Snapdragon Stadium (35,000 seats), San Diego International Airport Terminal 1, the San Diego County Sheriff's ASTREA hangar at Gillespie Field, and a 10,000 sq ft CommScope data storage facility.

Revenue is earned through project-based fees (percentage of project cost or fixed fee) and standalone finish service contracts, secured through direct enterprise field sales targeting university capital projects offices, government agencies, and commercial developers in the Southern California region. The company is led by CEO Jerry Zumbro, President Ryan Childs, and VP Colin Cronin, with no disclosed external institutional ownership, funding rounds, or M&A activity.
