While the City cannot recommend tree care companies, it is important to look for the following qualifications:

• ISA Certification Arborists. Arborists certified through the International Society of Arboriculture are experienced professionals who have passed a comprehensive examination on tree care and who also meet requirements for on-going education. 
• Education such as a degree in urban forestry, forestry, horticulture, arboriculture or related field.  
• Accreditation & Membership in professional organizations including the Tree Care Industry Association (TCIA), International Society of Arboriculture (ISA), American Society of Consulting Arborists (ASCA), and the Illinois Arborists Assocation (IAA). 
• Park Ridge Contractor Registration & Proof of Insurance. If the tree care company/arborist is not registered and uninsured, homeowners can be held responsible for any injuries or damage that may occur during the tree work.  
• Necessary Permits to perform tree work.  While the city does not require permits for pruning, a permit is necessary to remove a tree over 10" in diameter (measured at 4.5' from the ground) on private property.  Visit the FAQ page for more information on required permits.
