My firm employed The Riley Group for Geotechnical inspections and evaluations. Kristina was assigned to our project and was extremely helpful, professional and very good to work with. I give The Riley Group my highest recommendation.

Riley Group is an outstanding firm to work with. I have personally worked with them on over a dozen projects and found them to be very professional. Turnaround on projects, as well as their responsiveness, is second to none. I highly recommend using them for your geotechnical engineering needs.

I was referred by a Civil Eng with a host of other firms and happened to choose the closest Infiltration test company near me. David Baumgarten and team have been very exceptional in providing the service requested. The project scope was standard and after test holes were completed, they only billed for work required per test results and reports issued.

They were very timely with no escalation required. They provided very good and fair pricing, excellent support and even better after service. I will be reaching out to Riley Group for any future service needs.

As a commercial real estate lender in Western Washington for many years, I've always found The Riley Group to be professional, prompt, and efficient when engaged in assessing and reporting on environmental issues that may or may not be of concern to property owners and lenders.
