The best way to evaluate a professional tree worker is by seeing them at work. Here I encourage you to step into my office.
The TV program 'Heart and Hands' followed Will for a couple months in late 2014 to highlight his work in Oregon and Hong Kong.
Climbing old-growth Giant Sequoias (Sequoiadendron giganteum) to collect foliage samples as part of the Leaf to Landscape project, monitoring the ongoing effects of the California drought.

Working on a week-long project pruning 5 large Rain Trees (Albizia saman) in Ambon, Indonesia. The objective was to remove dead branches likely to break and damage historic gravestones below.
Replacing Katsura trees killed by the 2021 heat dome with more heat tolerant Silverleaf Oaks (Quercus hypodleucoides).
Climbing an old growth Douglas-fir (Pseudotsuga menziesii) for a film project. Land managers, public or private, are put at ease knowing that people working aloft in their lands are professionals with a long track record.
Climbing trees and rigging branches to the ground for epiphyte research in the cloud forests of Monteverde, Costa Rica.
Removing non-native Monterrey Pine (Pinus radiata) in Queenstown, New Zealand while working on a municipal contract.

2014 trip to Vancouver Island to assist colleagues in climbing and measuring Big Lonely Doug. This tree, the second largest known Douglas fir in Canada, was discovered after the entire forest around it was logged in late 2012. Learn more at the Ancient Forests Alliance website.
Collecting botanical voucher specimens from a large Mantadia tree in Eastern Madagascar.
Will earned first place in preliminary and final events at the 2014 British Columbia Tree Climbing Championship in Coquitlam, BC.

Practical, hands-on training for tree workers employed by the government of Hong Kong.
Making the initial ascent to remove a dead Aleppo Pine (Pinus halepensis) over a client's house in rural Namibia. The tree died due to drought stress.
Large stem failure on a Red Oak (Quercus rubra) in Portland, Oregon. Unfortunately this tree had to be removed due to this and other defects, though previously it was considered a good candidate for preservation. Preservation costs would have likely been far less than those of removal.
Climbing removal of a huge Chinese Hackberry (Celtis sinensis) in Hong Kong. This tree had been condemned by the government due to the risk it posed to pedestrians in a dense, urban environment.
Climbing removal of a large Garry Oak (Quercus garryana) tree with significant structural problems.
This mature spruce tree was pulled to failure with strain gauges attached to the roots to understand how trees' root systems absorb energy from the stem.

This American Sweetgum (Liquidambar styraciflua) was condemned by the city due to repeated failures. It was situated in a very busy section of downtown directly above the MAX light rail lines.
This photo shows retrenchment pruning of a severely drought damaged Eucalyptus camaldulensis. Although this pruning method may look superficially like topping, the reasons, methods and outcomes are very different.

A short video of one of the most unpleasant jobs I've done in my career: removal of a Chinese Hackberry (Celtis sinensis) in Hong Kong that had been completely overgrown with spiky Bougainvillea vines. Apologies for the gratuitous use of profanity; it couldn't be helped.
