Jacob Carroll
Started his surveying career in 1996 and quickly became the youngest Licensed surveyor in the United States. A graduate of Oklahoma State University, he quickly realized the advantages of LiDAR and Aerial Orthophotography over traditional survey methods.  He created Bearing Tree Land Surveying to utilize these new advances in surveying technology, to save clients time and money while providing the upmost level of accuracy and detail clients had not seen in the past.  Jake has served on numerous professional organizations, including the National Society of Land Surveyors, American Society of Civil Engineers and is a past president for the Oklahoma Society of Land Surveyors. Jake strives to provide clients with the latest and greatest in surveying technology, while advancing his knowledge through continued training/ education in the industry.


Mike Madden
A graduate of Oklahoma State University with over 16 years in the industry, Mike specializes in all things LiDAR, Orthophotography and Photogrammetry. From planning to acquisition to processing and extraction, he has developed a mastery over systems such as Leica, Optech, Phaseone and Bentley software. He understands the importance of safety and regulations that come with acquiring aerial data, and the process to work within restricted airspace.  Whether it be aerial,  terrestrial or mobile, Mike strives to provide clients with detailed point clouds and a higher level of accuracy that goes above and beyond the project specs.


Jonathan Nazari
A graduate of the University of Central Oklahoma, Jonathan has always been driven by a desire to make a difference in the world. Working for Bearing Tree Land Surveying for the past 13 years has allowed him to accomplish this through large and small civil engineering projects, that make communities across the US a more exceptional and dynamic place to live. An active member of the American Society for Photogrammetry and Remote Sensing since 2012. Jonathan has real-world experience with AutoCAD Civil 3D, Bentley GeoPAK, Bentley MicroStation v8i & Connect, PLS-CADD, TopoDOT 64 and the entire suite of Terrasolid LiDAR products. He continues to further his education by attending numerous civil engineering and DOT-oriented conferences, including taking part in the Oklahoma Department of Transportation OpenRoads Designer Standards Summit in 2022.
