Ross McCune - Owner & President

Caisteal Builders, Inc., A Premiere Commercial Construction and General Contracting Company

Established in 2003, Caisteal Builders, Inc. has built a reputation for excellence in Southern California as a commercial construction, general contracting firm. We specialize in design-build, design-assist, tenant improvements, structural rehabs, concrete tilt-ups, and LEED construction. Ross McCune is owner and president with over 30 years of experience in the Southern California construction market. Our approach to construction emphasizes listening to the clients needs and delivering results that meet current needs while providing flexibility for the client’s long-term goals. Each development plan incorporates current building codes and innovative options.

Great buildings are the result of detailed planning, uncompromising standards, skilled teams and thorough understanding of the client’s current needs and expected future. We carefully select every direct employee and engaged subcontractor. Detailed client planning and review meetings lead to weekly team meetings, and phase meetings to ensure on-time, on-budget project completions. We’re proud of our safety record and our compliance with OSHA standards.

"Let us build your building while you build your business."
