Certified Arborist: Nelson Tree Specialist

Not all tree service companies are created equal. At Nelson Tree Specialist, we have International Society of Arboriculture (ISA) Certified Arborist on our crew. We know our Maryland and DC customers deserve quality.

When a limb falls on your home, when a tree uproots during a bad storm, when your favorite tree starts growing a mysterious fungus, Nelson’s Certified Arborists are the most qualified to assist you.

What Does it Mean to be a Certified Arborist?


A lot about the tree service industry – best practices concerning pruning and tree removal – can be learned through experience. But there is certainly merit in being formally training in these areas.

ISA certifies arborists to competently undertake specialized tasks, such as emergency tree care, cabling and bracing, and plant health care. Non-ISA-certified workers will likely not offer many of these services, or the service will be substandard. 

ISA certifications are valid for a period of three years. Further, certification holders will likely have undergone continued education outside of the ISA.

Additionally, benefit of the ISA holding certification independently is it prohibits employers from self-qualifying their crew. The ISA is an independent certifier and holds no stakes in certifying unqualified participants.

Areas of Knowledge

Certification through the ISA is based on exam results. The exam is put together by some of the country’s leading tree care experts. Candidates test in ten general areas of study:

  • Pruning
  • Safe Work Practices
  • Tree Risk Management
  • Soil Management
  • Diagnosis and Treatment
  • Tree Biology
  • Identification and Selection
  • Urban Forestry
  • Installation and Establishment
  • Tree Protection

Rightfully, those who pass have the distinct honor of knowing they have achieved one of the highest levels of knowledge in the science and art of tree care.

Nelson Tree Specialist Hires ISA Certified Arborists

Our crew is uniquely able to assess your tree structure and make qualified recommendations for your trees. We look at old and overgrown trees to ensure structural integrity and overall health.

Also, we offer crown thinning. This is when we remove some live growth in order to let in more air and sunlight. If a tree begins to grow too densely, it can become susceptible to rot, mildew, and fungus.

We really do put your experience first. We are always learning and always coming up with new ways to better serve you. Our Specialty Arborists can assess your property for any defects in your trees, including:

  • Cracks and splits
  • Weak branches
  • Hanging or dead branches
  • Poor structure
  • Root-related defects
  • Lot clearing

Clearly, this is not easy stuff to deal with and not all tree services are equipped to help you.
