We started with a single truck, a set of Shelby tubes and a conviction that Southern California deserved a geotechnical firm that returned phone calls. That conviction still runs the practice.

Sable Canyon Geotechnical was founded in 2011 by Robert Ryan, a California-licensed Geotechnical Engineer with two decades of consulting on hillside and industrial projects across the Inland Empire. What began as a specialist practice serving a handful of custom-home builders has grown into a full-service firm supporting municipal, education and private-sector clients from Palm Desert to Long Beach.
We have kept the practice deliberately small. Every project is touched by a senior engineer, every field crew is trained in-house, and every deliverable is peer-reviewed before it leaves the building on Fincham Road.
Field data honestly collected, correctly reduced, and clearly explained. No shortcuts, no template-swaps, no ghost authors.
If your site has a problem, you will hear it plainly — with a path forward you can price and schedule.
The engineer who wrote your report is the engineer who returns your call three years later. That is rare, and it is deliberate.
