Who We Are
About KSF
The team behind KSF
KSF Structural is a dedicated team of licensed engineers, founded in Oakland in 1988 by Kent Ferre, P.E., S.E., and trained by him to one standard. Headquartered in the East Bay and now open in Los Angeles County and serving the Sacramento Region, we bring the same standard to every inspection, in every region. We look at your home the way you do: as the place your family lives. We explain what's sound, what's not, and what it takes — in plain English, without alarm, and without selling repairs.
