Our Crew


They Might Be Monkeys strives to put the most well educated and trained crew possible to work on our clients’ trees. We employ our crewmembers on a full time basis with an emphasis on continuing education and upward mobility in the tree care industry. As our employees develop we prepare them to become Certified Tree Workers. Once they meet the requirement of 18 months experience in the industry they have the skills and experience necessary to pass the hands on skills test and written exam for this certification. Once they have three years of experience they will have be ready to test for the certification of ISA Certified Arborist. Helping each and every one of our employees to reach this goal is very important to us. We provide a job site supervisor with ISA Certified Arborist qualifications on all of our sites. We pride ourselves on employing bright, intelligent, hardworking, and friendly folks who will be pleasure to have on your property.

Our Comprehensive Safety Program


It is very important to us that our workers and your property are kept safe during all aspects of our work. They Might Be Monkeys proudly meets or exceeds industry safety standards.

All of our climbers are certified in CPR/First Aid and have been formally trained in high angle rescue. We schedule regular safety meetings and provide regular continued education in job site safety. We carry high levels of liability insurance to protect our clients and workers compensation insurance to protect our crew. The safety of our crew, our clients, and our clients’ property is our highest priority.

Benefits of Consultation

Always consult with a Certified Arborist before bringing in the chainsaws. This will ensure that the eventual work performed on your trees meet with your needs and has minimal negative impact to the trees themselves. In most cases the consultation cost is a one-time expense. We are always happy to consult with established clients free of charge. Trees grow slowly, in order to treat them right we need to establish a long-term relationship with them and their environments.

  • Understanding your trees relationship with urban soil
  • Forming a long-term relationship with your trees. Learn what you and your family can do over the years to maintain optimal tree health.
  • Identify and understand the impact of invasive species on the landscape, urban forest, and in urban/wildland interface areas.
  • Learn about proper pruning practices, how and why trees respond to pruning, and about the process of Compartmentalization of Decay in Trees (CODIT).
  • Damage prevention/mitigation to trees during development, remodeling, or while making changes to the landscape.
  • Determining the legality of pruning or removing large trees and the impact of doing so on the urban forest.

Risk assessment and resolution.

  • Become informed about the inherent conflicts between trees and infrastructure and the importance of having the right tree in the right place.
  • Understanding tree pathology. Treatment recommendations are based on individual tree species, condition, and location.
  • Establishing a budget that is realistic for you in regards to the management of your trees and helping to set your tree tree care goals.
