Pitcher Services

Pitcher has made a name for ourselves in this industry. From the development of the Pitcher Barrel Sampler, to the high profile projects we routinely work on, we are a trusted name in geotechnical investigation.

Reliability – Flexibility – Expertise

Our commitment to responsive, reliable and expert service means solutions, savings and peace of mind to you and your organization.

Pitcher is directed and staffed by geotechnical professionals with experience in industry, consulting, and research.

We are proud of our agreement with the Operating Engineers union and our Alaskan Native ownership through Sealaska’s Woocheen group.


“I just wanted to compliment Bryce and Nathan on a job well done – they were great yesterday.  They completed the scope of work in good time with no hassle and got all the info we needed, despite the 106 degree heat.

Also, thanks again to you and your team for the great follow-through with getting our Purchase Order authorized on such short notice.” – Brand Burfield, Intertek PSI

“The well looks like a great success.  I must say that Will and the rest of your team did a great job under rather difficult circumstances.” – Peter Starr, Netcom

“I wanted to say great job to your CPT crew who did high-quality work yesterday [September 2023].” – Khashayar Amini, PE, Haley & Aldrich

“I also wanted to pass along the message that it nice seeing the crews work together. The CPT crew was looking for opportunities to help out the drill crew. For example, Bryce would get a wrench on the drill pipe whenever he saw a chance to help out.” – Client in San Francisco, September 2023

Delivering solutions through strong partnerships

For more than 90 years Pitcher has been delivering reliable and quality geotechnical and near-shore drilling and testing solutions. We are proud of our partnership with the Operating Engineers local #3 and #12 unions and our affiliation with Gregg Drilling and Sealaska.

A vision for healthy oceans

Pitcher Services is one of Sealaska’s businesses, which are focused on ocean health. These companies are united as Woocheen, a name derived from the Tlingit word wooch.éen. The word can be roughly translated as “working together with the resources and environment around us.” We often collaborate with Gregg Drilling and CS Marine here in California to provide a full suite of site investigation and marine construction services.
