Partner Network
At SFGEO, we know that geotechnical work is just one part of the puzzle. You might also need a surveyor, structural engineer, environmental consultant, or someone else along the way and finding the right people can be a challenge.
Over the years, we’ve built a network of independent professionals who share similar values: practical, reliable, and easy to deal with. While we don’t manage or coordinate their work, we’re always happy to point you in the right direction if you need a trusted contact.
Just so we’re clear, any professionals we refer are entirely independent. You engage them directly, and they operate under their own terms. We don’t take referral fees, and we’re not responsible for the outcomes of their work. We simply believe a helpful introduction can go a long way.
Here’s who we know and what they’re great at. Need a recommendation? Just reach out, we’re happy to help where we can.
