Our Firm

Welcome to D. Woolley & Associates. We are an established Land Surveying and Mapping firm providing a wide range of services to a diverse clientele. Licensed in the State of California and Nevada, we have the skilled staff, latest equipment and detailed survey methods to provide prompt and efficient service to our clients.


D. Woolley & Associates is well versed in state laws, local ordinances and standards of practice. We are often consulted as a specialist for work that ranges from property boundary disputes, map checking, horizontal and vertical geodetic control, ALTA/NSPS Land Title Surveys and monument preservation. We bring a level of commitment and professionalism to each project that meets or exceeds the standard of care required. From relatively small construction staking projects to large scale governmental QA/QC survey project management, we hold each task to the same standards.


A cornerstone of our business is providing services to public agencies and private companies that are in need of additional expertise not available to their in-house staff. This is largely due to two key elements that separate D. Woolley & Associates from other firms: our experience working for governmental agencies and our willingness to research and utilize new technology.


Our firm has established a reputation for serving our clients with strong performance, accuracy, innovation and professionalism and we continuously strive to remain on the leading edge of those qualities as we look toward the future.
