“We have been working with Winthrop for 2 years now and he has helped develop our new employees, recommended operational changes to improve efficiency and help improve morale among our crew. He does a debrief after every training day which is super helpful. He was an owner for years so he understands the business from the owner’s perspective. If you don’t have a trainer in your company this is an excellent option.”

- Daniel Mello, Board Certified Master Arborist, Seacoast Tree Care LLC

“Winthrop has been an outside trainer for us since late 2022. We have used him for multiple different aspects of training - for onboarding new hires, for developing climbers, for helping with foreman roles, and for training on the use of stick cranes in tree work as well. Winthrop has been an excellent communicator and developer of systems that we have put into place for everyone at our company to use and to follow. He helped set a standard for what we can base people’s experience off of, and for what we should be looking for in potential and current employees. He always gave us a debrief filled with constructive comments, suggestions and new things to implement for continuing training. We will certainly be using Winthrop again for multiple different training regiments that we need help on, and for creating more consistency throughout our normal day to day operations.”

“Winthrop was brought on as a contract climber and safety meeting coordinator about a year ago.  He brings an inordinate amount of skill to the table. As a contract climber specializing in pruning, Winthrop's pruning work is by far some of the most tasteful, most detailed, and arboriculturally correct work I've ever seen in comparison to the dozens of talented other arborists that I've hired/worked around. He takes no shortcuts in his pruning work.  His approach to his work is methodical, safe and strategic. Winthrop is mature, humble, upbeat, consistent and also politely offers input.  In terms of our safety meetings, he preps and coordinates our weekly safety meeting.  He comes prepared and manages the meeting with confidence, humility and grace.”

“Winthrop worked with many employees here at Barrett Tree Service East as a contract arborist trainer. He helped promote a safe work culture, helped individuals expand their skill set, and helped us implement and improve our own internal training process. Winthrop worked one-on-one with our employees. Together we would identify skills that individuals needed to work on and then Winthrop would create a lesson plan aimed at teaching those skills. While training, Winthrop was careful not to slow down the whole crew but still took the time and patience to train the individual. These lessons were effective. Winthrop takes a no-nonsense approach to safety culture and proper arboriculture and it shows! At the end of each day Winthrop would review his lesson with his student and also debrief me on the daily training. I would absolutely bring Winthrop back to do more training in the future and I highly recommend him to other tree service companies looking to invest in their employees.”
