About Us

A legacy of surveying

Wes Thomas Associates has dedicated itself to land surveying since our founding in 1975. Based in Kailua-Kona on the Big Island, we’ve completed thousands of projects across all the major Hawaiian Islands and the Pacific Basin.

Surveying Hawaiʻi since 1975

Wes Thomas Associates has dedicated itself to the discipline of land surveying since its inception in 1975. This singular focus has allowed us the luxury of dedicating our staff, equipment, and facilities to one specialized profession.

The firm has completed thousands of individual survey projects since founding. Our office in Kailua-Kona is managed by President and Chief Surveyor Chrystal Thomas Yamasaki, LPLS, with an aggregate staff experience of over 100 years providing professional land surveying services in Hawaiʻi and the Pacific Basin.

We’re familiar with the processes of the County and State of Hawaiʻi governments, along with economic and physical conditions that affect work schedules, costs and project completion. No project is too large or too small.
