Specializing in tree removal, pruning, and vegetation management  

Serving Central Oregon Since 2010

Timber Stand Improvement


TSI was founded in 2010 by ISA Certified Arborist, Nate Goodwin on the principles of safety and efficiency in tree work.

We specialize in residential and commercial tree work, including

tree removal, trimming and stump grinding.


Tree Removal

  • We specialize in the safe take down and removal of large dangerous trees in tight quarters, employing all the industry safety standards and rigging practices to ensure a safe work environment and to mitigate the hazard on your property.  

  • We use late model equipment for the most efficient and safe means of debris removal.

Tree Removal

Tree Pruning/Trimming/Cabling

  • Tree pruning is the priority for the preservation of your trees.  

  • All dead, broken or damaged branches should be removed to increase airflow, reduce areas of decaying wood that pests harbor in, improve aesthetics and most importantly improve the overall safety of your tree.

  • Clearance trimming/pruning to provide adequate clearance to buildings, driveways, streets, walkways, etc. 

  • For pruning, we never use climbing spikes to access the tree as it compromises the health and aesthetics of the tree. We set climbing lines to provide a minimally invasive way to access the work. 

  • We install dynamic cable bracing systems to help preserve multi-stemmed trees. This reduces the likelihood of tree failure at those notoriously weak unions, while still leaving room to grow and react in the wind. We recommend having these systems inspected every 1-2 years.

Tree Stump Removal

  • Stump grinding is the best way to remove an unsightly stump. Typically we grind it down to below finished grade and either rake out the grinding mulch or remove it. We do not recommend planting new trees directly on old stump sites. 

  • Our stump grinder can get through a 36" wide gate, and treads lightly over existing landscaping to minimize impact.

ISA Certified Arborist Consultation

ISA Certified Arborist Consultation

  • By hiring an ISA Certified arborist to provide guidance on your trees, you are ensuring that you are getting the most up to date and pertinent information on your trees. 

  • Whether it's just advice you're seeking about your trees or a full work plan to be developed with a quote we can help you arrive at your tree goals.

  • Tree Risk Assessment Qualified (TRAQ) is a service we offer to provide you information about your tree of concern and help you decide your level of comfort around it.

Forest Management

  • Thinning and removing the smaller, overgrown trees away from the larger more established ones will ensure proper tree health for years to come. 

  • Thinning promotes forest health, leaving a better growing environment with proper spacing, airflow, and optimal light and water availability.  

  • Thinning trees helps to ensure wildfire readiness. 

  • Heavy fuels reduction: Removing downed logs and slash in forested areas reduces the burn intensity should a fire come through. 

  • Brush mowing to remove or reduce brush is the most efficient way to mitigate fire risk while leaving the mulch debris as nutrient recovery to the soil. 

  • Drought readiness: Thinning and removing overgrown trees, or invasive trees will give your remaining, desired trees more resistance to drought conditions.
