DendroDiagnostics is a consulting firm operating from the Columbia area of South Carolina specializing in Diagnostic Arboriculture and Forestry. Our primary Arborist, Forester, and Diagnostician, is retired from the South Carolina Forestry Commission, where he headed the Forest Health Unit. He has over 45 years of experience in diagnosing insect, disease, and physiological problems affecting South Carolina’s urban trees and forests. Educational qualifications include a Master’s Degree from Duke University in Forest Entomology and Pathology. He is also an S.C. Registered and SAF Certified Forester, an International Society of Arboriculture Certified Arborist with Tree Risk Assessment Qualifications, and an S.C. Commercial Pesticide Applicator.

Our services are provided directly to S.C. homeowners, businesses, and others who contract with us. We have no financial ties to any other Arborists, Tree Services, or Forestry companies. After diagnosing your trees’ problems, our Arborist will work with you to find local service providers to perform the needed treatments for healthy tree maintenance. Our impartial status means that you can be sure all of our recommendations are based on the best science and tailored to your situation. This should save money for our customers since we never pressure clients to undertake unnecessary treatments. We will always advise clients if there is little chance of any therapy being successful. Sometimes “saving trees” with overwhelming problems is not possible at any price, and tree replacement is a better option.

Our services are also available in other areas. We provide diagnostics, surveys, and related services throughout South Carolina for Forests, Landscape Nurseries, and Christmas Tree plantations. We can provide talks or training in any of our areas of expertise. Since we are centrally located in the Columbia area, we can travel to any site in South Carolina in three hours or less.

Our work week is Monday – Saturday, and we may be contacted at (803) 345-1148. For more details, see the ”Contact Us” page.
