The firm began offering surveying services in 1952 as a continuation of the practice of Frank Kelly, County Surveyor of Humboldt County. The firm has been in continuous operation since that time and was incorporated as Kelly-O’Hern Associates in 1985.
The firm has extensive experience in timber and ranch surveys, as well as subdivision and construction surveying. Litigation surveying has been a specialty throughout the history of the company.
Primary areas of practice are Humboldt, Del Norte, Trinity and Mendocino Counties. We have worked in Shasta County, Sonoma County and Yuba County.
