The Accreditation Process

The Tree Care Industry Association (TCIA) is the only industry organization that inspects and accredits tree service companies based on strict adherence to industry business ethics, consumer satisfaction, and technical competence.

Originally established as the National Arborist Association in 1938, our company founder was an early member in good standing with the association. Accreditation by the TCIA requires meeting these standards:

  • A 63-point checklist for approval
  • On-site company audit
  • Up-to-date insurance
  • Company history/safety procedures
  • Tree care knowledge/experience

Since 1930, Nels Johnson Tree Experts has proudly carried on our long tradition of excellence as evidenced by our TCIA accreditation. You can call us knowing our company meets the most stringent criteria in industry-approved tree care practices, while providing the highest standards of ethical, reliable service.
