SJC Building Services was founded in 1996 by Mark Conrad with a single conviction: that clients deserve to know exactly what they're paying for, and exactly what they'll get. Nearly three decades later, that commitment is still the foundation of every project we take on.
Mark leads every project personally — from the first consultation through the final walkthrough. We bring in-house architecture, permit management, and construction under one roof so you have one point of contact and zero hand-offs.
