Services Specialty Projects

Expert Witness

An Expert Witness is allowed to give opinions in a trial or hearing due to specialized knowledge in a scientific or technical field; in this case, the field of arboriculture. We have expert witness training through the American Society of Consulting Arborists, as well as experience testifying in court, depositions, and hearings. 

Our team is well respected for its superior communication skills and pragmatism. Many of our clients have been able to settle before going to trial. Please contact us for more information.


We provide accurate valuations and appraisals of trees and plants for insurance claims, legal cases, or other needs. We use the Council for Tree and Landscape Appraisers Guide to Plant Appraisal, 9th and 10th Editions, which are considered an industry standard. We have used the Trunk Formula Method with success in numerous legal cases. We also use other methods when appropriate including the Replacement Cost Method and Cost of Cure Method.

Our firsthand experience developing and managing bids for tree work and restoration projects allows us to make accurate replacement and restoration cost appraisals.

Design & Restoration

We design plans for retaining or restoring natural areas and related native understory plants in landscapes. Services can be as simple as recommendations for drought-tolerant plantings to fit your situation or a more complicated neighborhood greenbelt restoration. Landscape design can be included with tree protection planning or tree inventory services.

Training, Research, Education

We have experienced public speakers and arborists on staff who can educate groups on tree diagnostics, construction, and urban forest issues. We have presented to groups of hundreds, given virtual presentations, and assembled courses for professionals. We can adapt to any audience and knowledge level, from high school classes, to municipal landscape crews, to neighborhood groups.
