We don’t just have ISA Certified Arborists on staff—we also employ ISA Board Certified Master Arborists (we have not one but two), representing the pinnacle of arboricultural expertise. When your project requires specialized knowledge for tree risk assessment, risk mitigation, canopy evaluation, or target assessment reports, our team of certified professionals stands ready to deliver industry-leading consultations.

Comprehensive Tree Risk Assessment Services

Tree risk assessments are critical evaluations designed to identify unhealthy or damaged trees that may pose significant risks to people and property. Our certified arborists conduct these assessments with meticulous attention to detail, following the industry’s most rigorous standards. Depending on your specific needs, we offer three distinct levels of assessment:

Level 1: Limited Visual Assessment

  • Perfect for initial evaluation of large properties or multiple trees
  • Conducted by walking or driving past trees to identify obvious high-risk specimens
  • Efficiently screens multiple trees to determine if more detailed assessment is needed
  • Includes a professional summary report of findings with basic recommendations

Level 2: Basic Assessment

  • Involves a comprehensive 360° visual inspection of individual trees
  • Conducted without specialized tools but with expert observational techniques
  • Includes detailed documentation of species, diameter at breast height (DBH), structural defects, and risk factors
  • Provides a thorough risk assessment and mitigation report for each evaluated tree
  • Offers clear, actionable recommendations based on professional judgment

Level 3: Advanced Assessment

  • The most comprehensive evaluation for high-value or high-risk trees
  • Utilizes specialized equipment including bucket trucks for canopy access, compressed air tools for root collar examination, resistograph for decay detection, and sonic tomography
  • Delivers in-depth analysis of roots, stem, or crown conditions
  • Includes a detailed professional report with field observations, photographic documentation, testing results, and multiple recommendation options
  • Provides the data needed for making critical decisions about valuable or hazardous trees
