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.
