"Nathan worked on a high stakes prescriptive easement case for me. His report combined data from multiple years and sources. It was a big part of the court ruling in my favor. I am forever grateful for his work."
-A.L., Client
"We have worked with Nathan on several environmental, land use, zoning, and other property cases where historic aerial images of changes in land use have provided critical evidence supporting our clients' arguments. His analysis is always thorough and precise and his presentations of complex technical material are clear and easy to immediately apply for our clients' benefit. I look forward to working with Nathan on future cases and highly recommend him to other litigators handling property and environmental cases."
