Tree work affects the long-term health and safety of your property. The right cuts, timing, and techniques protect structure, prevent decay, and reduce risk during storms. The wrong approach can do the opposite. That’s why choosing an ISA-Certified Arborist matters. These professionals pair real-world experience with formal training in tree biology, safe work practices, and risk assessment to deliver reliable results.
When you want tree work done right in Maryland, hire an ISA-Certified Arborist. Nelson Tree Specialist brings that standard to every job. From structural pruning and targeted removals to plant health care and emergency response, we follow proven methods, use the proper equipment, and prioritize safety and clear communication.
Before you select a tree company, it helps to understand what this credential actually represents.
What ISA Certification Really Means
ISA (International Society of Arboriculture) certification goes far beyond a one-time test or a marketing label. It verifies education, field experience, and ongoing learning focused on tree biology, safety, and industry standards. The International Society of Arboriculture bases certification on rigorous exam results developed by leading tree care experts.
A lot in the tree service industry, especially best practices for pruning and safe tree removal, is learned through hands-on experience. But formal training matters. ISA certifies arborists to competently perform specialized tasks such as emergency tree care, cabling and bracing, and plant health care. Workers without ISA credentials may not offer many of these services, or the quality may fall short.
ISA certifications are valid for three years, and credentialed arborists typically complete continuing education beyond ISA’s minimum requirements. Another key benefit is that ISA is an independent certifier, which prevents employers from “self-qualifying” their crews and helps ensure only qualified professionals hold the credential.
ISA’s exam measures knowledge across ten core domains:
- Pruning
- Safe Work Practices
- Tree Risk Management
- Soil Management
- Diagnosis and Treatment
- Tree Biology
- Identification and Selection
- Urban Forestry
- Installation and Establishment
- Tree Protection
Candidates must demonstrate broad competency in both the science and the craft of arboriculture. Those who pass earn one of the most respected credentials in tree care.
